A review of the genus Narcissia Gray, 1840 (Echinodermata: Asteroidea: Ophidiasteridae)

Article

J MAR BIOL ASSOC UK

Since the taxonomic revision of the Ophidiasteridae by H.L. Clark (1921), in which 20 genera were recognized as valid, several new genera and species were included in this family, and the boundaries between some of them became largely arbitrary. This also applies to Narcissia Gray, 1840, whose morphology and taxonomy are still very poorly understood today. The main goals of this research were: review the taxonomy of the genus Narcissia, from morphological studies; redescribe N. trigonaria Sladen, 1889 s. str.; characterize N. canariensis (d'Orbigny, 1839) and N. gracilis A.H. Clark, 1916, the two valid species most similar to N. trigonaria; review the validity of N. ahearnae Pawson, 2007 and N. trigonaria var. helenae Mortensen, 1933; review the validity of N. gracilis malpeloensis Downey, 1975. Altogether 370 specimens were analysed. All morphological structures of taxonomic importance have been illustrated, and, for the first time, the internal characters of this group were studied, from electron microscopy and microtomography. A new diagnosis for the genus Narcissia was constructed. Narcissia trigonaria was redescribed from a large specimen, from the type locality (Bahia, Brazil). Narcissia ahearnae is considered a valid species, and N. canariensis and N. trigonaria distinct entities. Narcissia trigonaria var. helenae is placed in the synonymy of N. trigonaria, and N. gracilis malpeloensis into the synonymy of N. gracilis. The dataset obtained in this work is by far the most complete acquired for the genus Narcissia.

New record of the red prickly sea star Paulia horrida (Gray, 1840), Asterodiscididae, in the north of Chile

Oct 2021

We report the capture of a single specimen of the species Paulia horrida Gray, 1840, off the coast of Arica, in the Arica and Parinacota Region, Northern Chile. This finding extends the currently known distributional range of the species by 2,434 km towards the south, since the southernmost known area for this species corresponds to Punta Sal, Peru. We discuss the importance of finding this relatively unknown species in Chile and the need to continue sampling to confirm the continuous distributional range of the species between the south of Peru and the north of Chile.

Two partial mitochondrial gene sequences (COI and 12S-rRNA) suggested that Ceramaster japonicus (Sladen, 1889) and Ceramaster patagonicus (Sladen, 1889) (Asteroidea: Goniasteridae) from the Japanese waters are probably of the same species

Article

Oct 2019

Our recent morphological studies on the echinoderm collection of the National Museum of Nature and Science, Tokyo (NMST), indicated that the goniasterid starfishes Ceramaster japonicus (Sladen, 1889) and Ceramaster patagonicus (Sladen, 1889) are distributed in the Pacific Oceanside of Japan. In this study, we studied the NMST samples of C. japonicus and C. patagonicus from Japan, by using two mitochondrial DNA genes, the COI and 12S-rRNA, as markers to test relationships between these species in Japan. C. patagonicus sequences from GenBank were mined and included in the analyses. Results of phylogenetic and haplotype network analyses of both genes (final sequence lengths: COI = 317 bp, 12S = 477 bp) suggested that "Ceramaster patagonicus" and "Ceramaster japonicus" from Japanese waters are almost certainly synonymous without any population structure inside Japan.

Checklist of echinoderms (Echinodermata) from the Southern Mexican Pacific: A historical review

Article

Full-text available

Jul 2015

The echinoderms of the Southern Mexican Pacific have been studied for three centuries, but discrepancies in the nomenclature of some species have pervaded through time. The objective of this work is to present the first updated checklist of all valid species and synonyms, and a historical review of the study of the echinoderms of the Southern Mexican Pacific is also presented. The checklist is based on an exhaustive published literature search and records of specimens deposited in museum and curated reference collections. There are 162 species of echinoderms in the Southern Mexican Pacific from 96 genera, 54 families and 20 orders. The State of Guerrero presented a total of 135 species, Oaxaca 94 and Chiapas 15. We updated the list and added five new records of the species (Microphiopholis platydisca, Ophiostigma tenue, Arbacia stellata, Thyone bidentata, Chiridota rigida) for the Southern Mexican Pacific and one for the Mexican Pacific (Encope laevis). This checklist expands the number of species known for the study area; nevertheless studies suggest that still more species are yet to be discovered

Taxonomic status of the oreasterid sea star Bothriaster primigenius Döderlein, 1916 (Echinodermata, Asteroidea)

Article

Oct 2023

One of the oreasterid sea stars, Bothriaster primigenius, is a rarely encountered species in the tropical Indo-West Pacific. The taxonomic position of this species, and more specifically, whether to recognize this sea star as a species, remains unresolved. To resolve the question, we assessed the specific validity of this sea star based on morphological observations and molecular phylogenetic analysis. The results revealed that this species is a young individual of another oreasterid sea star, Choriaster granulatus, and is placed as a junior synonym for the same.

Oct 2017

A sea star was collected from the Korea Strait in the waters adjacent to eastern Jeju Island, Korea (33°39′86″N, 127°33′12″E) at a depth of 92 m on November 5, 2016. This specimen was identified as Marginaster paucispinus Fisher, 1913, from the family Poraniidae of the order Valvatida, based on morphological characteristics. The genus Marginaster Perrier, 1881 and M. paucispinus, which were first reported in the South China Sea, are new to the Korean fauna. Partial sequences of mitochondrial COI and 16S ribosomal RNA of M. paucispinus were have been determined for the first time and were deposited in GenBank. They are the first molecular records for the genus Marginaster.

Objective: To study the echinoderms diversity in Mudasalodai and Pazhayar landing centers during November 2012 to December 2014. Methods: All the collected echinoderm samples were stored at 4 °C until further use. Results: As many as 19 species of echinoderms were recorded in both stations and it belongs to 10 families, three classes such as Asteroidea, Echinoidea and Ophiuroidea. The percentage composition varied from 0.15% to 73%. The species diversity ranged from 1.031 to 2.6; species richness was from 1.02 to 4.06 and species evenness ranged from 0.93 to 0.99. K-dominance curve drawn paralleled the trend of diversity indices. Cluster and multidimensional scaling showed the similarity in echinoderms composition within the stations. Conclusions: The present investigation is evident that the echinoderm occurrence was predominant during the summer season and proved statistically by using SPSS Primer 6.0.

ZOOTAXA

Sea stars were collected at depths ranging from 91 to 160 m around Kumejima Island situated in the middle of the Ryukyu Islands chain in the Western Pacific. Sampling was carried out using a dredge or beam trawl in November 2009, as part of the KUMEJIMA 2009 Expedition. The specimens included an undescribed species of the genus Neoferdina, and three species that have never been reported in Japanese waters. Features that characterise this new species, Neoferdina longibrachia, include: extremely long and narrow arms, no alternating arrangement of large and small superomarginal plates, body surface (except for the marginal plates) completely covered with granules, and an adambulacral armature with 3 furrow spines.

During a series of cruises aboard the R/V "EI Puma" aimed at collecting the deep-water benthic and pelagic fauna off the Pacific coast of Mexico, in the eastern Pacific, samples of Asteroidea were collected below 500 m depth (587-1 526 m). A total of 335 specimens were collected, belonging to 18 species, 14 identified to species, 3 to genus, and 1 previously undescribed species. New records are provided for Dipsacaster laetmophilus Fisher, 1910, Myxoderma sacculatum (Fisher, 1905), Peribolaster biserialis Fisher, 1905, Ampheraster chiroplus Fisher, 1928, Ampheraster hyperoncus (H. L. Clark, 1913), Anteliaster coscinactis Fisher, 1923, Nearchaster aciculosiis (Fisher, 1910), Ceramaster leptoceramus (Fisher, 1905), Mediaster transfuga Ludwig, 1905, and Lophaster furcilliger Fisher, 1905. All species were collected below the oxygen minimum zone that extends throughout the central and southern Gulf of California, or within the threshold zone where severe to mild hypoxic conditions prevail. Epibenthic dissolved oxygen concentrations associated with the capture of the specimens show support for strong tolerance to severe hypoxia (<1.0 ml O 2/l) for most species, but only mild hypoxia for Ctenodiscus crispatus (Retzius, 1805), and Nymphaster diomedeae Ludwig, 1905. A checklist of all species of Asteroidea occurring below 500 m depth off the Pacific coast of Mexico is included.

Echinoderm Research and Diversity in Latin America

Chapter

Full-text available

Jan 2013

Latin America (LA) includes all countries in the Americas that speak Spanish or Portuguese; in total it includes 22 countries including Mexico, Central America, the islands of the Caribbean and South America and Haiti (Hispaniola Island, shared with Dominican Republic). This book is divided in 16 chapters and two taxonomic lists with information about presence/absence, bathymetric range and the habitat or substrate where the species have been found. Fourteen chapters deal with studies done in countries, regions or islands. The final chapter has a biogeographical and diversity analysis of the two taxonomic lists. Each country chapter contains six sections. 1. An introduction. 2. A historic account of the investigations on echinoderms. 3. Distributional patterns and diversity. 4. Fishery or aquaculture activities. 5. Threats to echinoderms, and 6. A final section with general conclusions from the review and recommendations for future research to meet the needs of each country. Latin American echinoderm studies started a long time ago, as far back as the 13th century. The most common threats to echinoderms are bad coastal planning, coastal pollution, illegal fisheries, inefficient fisheries management, lack of protection, and lack of baseline studies. A total of 1,539 species (21.8 % of the worldwide species) are included in the taxonomic lists (appendix), with 717 species in the Pacific and 926 in the Caribbean and Atlantic. The richest class is Ophiuroidea followed by Asteroidea. All classes have more species in the Caribbean and Atlantic than the Pacific.

Asteroid (Echinodermata) skeletal elements from upper Oligocene deposits of Jamaica and Antigua

Article

Full-text available

Apr 2015
GEOL MAG

The Antillean Cenozoic fossil record of asteroids comprises mainly dissociated ossicles. Most common among isolates from upper Oligocene deposits of Jamaica and Antigua are marginal ossicles of an extinct, indeterminate species of Pycinaster. This is the youngest known occurrence of the genus and the first from beyond Europe. A number of relatively complete fossils have been assigned to Pycinaster and (sub)familial status proposed for it together with Phocidaster. The latter proposition is based solely on a few marginals, but available diagnoses are judged insufficient to justify such recognition. The taxon Pycinasteridae is here synonymized with the Goniasteridae, although future study of added features (such as the ventral surface) might justify recognition at a higher taxonomic level. In addition to ossicles assigned to Pycinaster, many marginals are tentatively assigned to the surviving goniasterid Nymphaster. Numerous generic and many species names have been based on asteroid isolates, but the practice demands assumptions that are not readily justified. Linkage of discrete isolates under a single taxon name assumes derivation from a single source, an inference that can be verified only rarely (if ever), therefore reducing names to the single holotype ossicle. Availability of only isolates encourages comparison with extant taxa and biogeography, biasing interpretations with a Holocene overlay. Because of these constraints, a new nominal species of Pycinaster is not justified and assignment of ossicles to Nymphaster is tentative. However, given the importance of asteroids in marine communities, we emphasize the significance, largely ignored, of their presence in Cenozoic deposits of the wider Caribbean.

A New Asterinid Sea Star, Disasterina akajimaensis (Echinodermata: Asteroidea) from the Ryukyu Islands, Japan, with Notes on the Genus Disasterina

Article

Jan 2012

Masaki Saba

A new asterinid, Disasterina akajimaensis sp. nov., is described from a specimen collected at Akajima Island, the Ryukyu Islands, Japan. It is clearly distinguishable from its five congeners by the following diagnostic characters: body relatively low and flat, uncalcified interradial areas conspicuous on ventral interradii, papulae numerous in center of disc, abactinal plates mostly lacking spinelets, inferomarginal plates with 2-4 spinelets, actinolateral plates with 1 spine, oral plates with 4-5 oral spines and no suboral spine, adambulacral plates with 1-3 furrows and 1 subambulacral spine. This is the first report of this genus from Japanese waters. Notes on the genus Disasterina and a tabular summary of the characters of the currently known species are also given.

Global distribution patterns of genera occurring in the Arctic Ocean deeper 2000 m

Article

Full-text available

Dec 2013

A list of genera represented in the abyssal (>2000 m) of the Arctic Ocean was compiled for 8 classes (Scaphopoda, Bivalvia, Crinoidea, Echinoidea, Holothuroidea, Asteroidea, Ophiuroidea and Ascidiacea) and some orders from the classes Anthozoa, Maxillopoda and Malacostraca. This list includes 92 genera and 133 species. Species endemic to the Arctic Ocean comprise 51% whereas species endemic to the Arctic abyssal comprise 19%. Only two small genera are endemic to the Arctic Ocean. Genera with a worldwide distribution (60 genera or 65%) dominate the Arctic abyssal fauna. Most genera (55 or 60%) can be considered as deep-sea specialists, with half or more of the species in each genus occurring deeper than 2000 m. About one third of genera (37%) are known outside the Arctic in the hadal zone (>6000 m). The share of genera known from the hadal is probably higher in the Arctic abyssal than in the abyssal of other oceans. For many genera, the worldwide minimum or maximum of their depth ranges is found in the Arctic Ocean. Distribution patterns of genera suggest that many deep-sea Arctic species derive from their congeners distributed in geographically distant regions (primarily the Southern Ocean and the Indo-West Pacific). The deep-sea North Atlantic was the main transit region on the pathway to the Arctic. There is no firm evidence of the presence of derivatives of the pre-Pliocene deep-sea Arctic fauna in the modern Arctic fauna. Twelve genera (13%) with a worldwide distribution are recognized as the most reliable examples of the emergence of the abyssal fauna in the Arctic Ocean. Two genera (2%) are characterized by the following distribution and ecological patterns: (1) distribution is limited to the Northern Hemisphere, (2) wide bathymetrical range (from shelf to abyssal), (3) abyssal records only within the Arctic Ocean, and (4) very wide ranges of habitats. Arctic submergence of the shelf fauna to the abyssal zone is suggested for these genera. Some higher taxa, not considered in the present work in detail, may have a high share of genera with similar distribution patterns. For instance the share of genera having submerged from the Arctic shelf to the abyssal is about 25% in the abyssal Arctic amphipod fauna.

Distribution of asteroid genera (Echinodermata) off South Shetland Islands and the Antarctic Peninsula

Article

Full-text available

Jan 2001

Frequency and distribution of asteroid genera in the South Shetlands zone are analysed, based on data from 24 Agassiz trawls carried out during the Bentart 95 Survey. Asteroids were collected at more than 90 % of the stations, on all types of bottoms, with richness per station ranging from 0-10 genera. The specimens belonged to 27 genera and 12 families, with Astropectinidae, Goniasteridae and, above all, Asteriidae having the highest number of representatives (3 and 7 genera, respectively). Odontaster Verrill, 1880 and Labidiaster Lütken, 1872, followed by Psilaster Sladen, 1885 and Diplastrias Perrier, 1888, were found to have the widest distribution and highest occurrence. Odontaster was more frequent to a depth of 100 m, and Labidiaster between 200 and 300 m. The rarest genera were Notioceramus Fisher, 1940 and Chitonaster Sladen, 1889, endemic to Antarctic waters. Stations showing the highest richness (10 genera) were those located near the Antarctic Peninsula and north of Livingston Island. Asteroid poverty was noticeable inside Deception Island, where a mere 3 genera were recorded. As shown by similarity and grouping analysis based on presence-absence data, stations are mainly grouped in relation to genera richness when double absence is considered. These results show the distintiveness of the stations around Deception Island, probably due to its special geological characteristics.

This paper reports on an orphaned collection of echinoderms housed at the Durban Natural Science Museum, South Africa. The collection includes holotypes of the South African endemic ophiuroid Asteroschema capensis Mortensen, 1925 [=Asteromorpha capensis (Mortensen, 1925)] according to Okanishi et al. (2013) and the South African endemic asteroid Anthenoides marleyi Mortensen, 1925. The holotype of the asteroid Hacelia superba var. capensis Mortensen, 1925 has not been found and is considered lost, whilst the holotype of Anthosticte pacei Mortensen, 1925 [=Tethyaster pacei (Mortensen, 1925)] is reported to be housed in the Zoological Museum Copenhagen, Denmark. The collection includes both wet and dry specimens of extant Asteroidea, Ophiuroidea, Echinoidea and Holothuroidea with Crinoidea being absent. Holothuroidea were excluded from examinations due to lack of locality data. In addition, Plococidaris verticillata (de Lamarck, 1816) is a new distribution record for South Africa. This paper gives new accession numbers of the specimens and the only photographic record of this collection.

This paper reports several new occurrences for Asteroidea and Echinoidea in Hong Kong. New records for asteroids include Anseropoda rosacea, Aquilonastra cepheus, Pentaceraster alveolatus, Pentaceraster sibogae, and Culcita novaeguineae. For echinoids, new records include Coelopleurus maculatus, Eucidaris metularia, Prionocidaris baculosa, Echinostrephus molaris, Pseudoboletia indiana, Salmacis bicolor, Stomopneustes variolaris, Toxopneustes pileolus, Clypeaster reticulatus, Metalia spatagus, and Nacospatangus altus. Several novel ecological observations on behavior, diet and morphological variation are also described. These additional occurrences and new observations are attributed to more comprehensive reporting from SCUBA diving as well as the advent of shared resources from social media platforms.

Michel Jangoux

Since its foundation in 1793, type specimens of 441 asteroid species and subspecies have been deposited in the Musum national d'Histoire naturelle of Paris. The annotated catalogue of all these taxa is drawn up including species whose type material could not be found in the collection. Today the Paris museum houses 1011 asteroid type specimens representing 398 nominal species and subspecies, most of which were described by Lamarck (1816), Mller & Troschel (1842), Perrier (between 1869 and 1896) and Koehler (between 1895 and 1923). Though originating worldwide, species coming from the Atlantic and Indo-West Pacific Oceans, and Antarctic waters are more numerous. A biographical directory of all those involved either in the descriptions of the species or the collection of new material as well as their dedicatee is annexed to the catalogue. Revision of the Paris collection allows to propose taxonomic changes for two species of Mller & Troschel (Echinaster crassus Mller & Troschel, 1842 and Echinaster gracilis Mller & Troschel, 1842 are synonymized with Echinaster purpureus (Gray, 1840)) and five species of Perrier (Asterias borbonica Perrier, 1875 and Echinaster clouei Perrier, 1869 are synonymized with Echinaster purpureus (Gray, 1840), Oreaster clouei Perrier, 1869 and Oreaster mammosus Perrier, 1869 with Protoreaster lincki (Blainville, 1830) and Ophidiaster chinensis Perrier, 1875 with Ophidiaster granifer Ltken, 1871).

Un rpertoire biographique de toutes les personnes impliques dans la description des espces ou dans la rcolte des spcimens types ainsi qu' leurs ddicataires, accompagne le catalogue en annexe. La rvision de la collection parisienne permet de proposer des changements taxonomiques pour deux espces de Mller & Troschel (Echinaster crassus Mller & Troschel, 1842 et Echinaster gracilis Mller & Troschel, 1842 sont synonymes de Echinaster purpureus (Gray, 1840)) et cinq espces de Perrier (Asterias borbonica Perrier, 1875 et Echinaster clouei Perrier, 1869 sont synonymes d'Echinaster purpureus (Gray, 1840); Oreaster clouei Perrier, 1869 et Oreaster mammosus Perrier, 1869 de Protoreaster lincki (Blainville, 1830); Ophidiaster chinensis Perrier, 1875 d'Ophidiaster granifer Ltken, 1871).

Sea Stars of Families Ophidiasteridae and Goniasteridae (Echinodermata: Asteroidea) from the Mesophotic Zone of the Ogasawara Islands, Including Two New Species

Article

Jan 2021

Five species of sea stars of the families Ophidiasteridae and Goniasteridae including two new species, Bathyferdina caelator sp. nov. and Fromia labeosa sp. nov., were collected by dredging from the mesophotic zone of the Ogasawara Islands, Japan. Bathyferdina caelator is distinguished from B. aireyae Mah, 2017 by the presence of glassy bosses (crystal bodies) on actinal and adambulacral plates and the absence of them on marginal plates. Fromia labeosa has large, elliptical pedicellariae on the actinal plate and is further distinguished from its congeners based on characters of the abactinal and superomarginal plates, granules, actinal papulae, furrow spines, and the subambulacral spines. We also provide descriptions for three mesophotic species, Fromia eusticha Fisher, 1913, Ogmaster capella (Müller and Troschel, 1842), and Tamaria tenella (Fisher, 1906), which are poorly studied in Japanese waters.

Paragonaster felli n. sp. (Echinodermata, Asterozoa) and a record of an Ophiuroid from the Early Cretaceous of New Zealand

Article

Jun 2020

Graeme R. Stevens

Two fossil Echinoderms, a starfish (asteroid) and a brittle star (ophiuroid), are described in this paper. They were found in sandstones of Early Cretaceous age in the Te Urewera National Park, East Coast, North Island. The asteroid holotype, EC 192 Paragonaster felli n. sp., is well preserved, except that the disc lacks the integument (i.e. skin). The exposed internal structures, however, are well preserved. Five pointed arms are present, two of which are well preserved for their entire length. Varying lengths of the other three arms are obscured by matrix. The Ophiuroid, EC 194, found with the asteroid, consists of a central pentagonal disc. The mouth is edged by pairs of small triangular oral plates. Four curved arms radiate out from the disc and are distinctly demarcated from the disc. One arm is a stump. The arms are thin, smooth and almost cylindrical. No structure is visible.

While the studies on echinoderms of the Mexican Pacific are vast, their biogeography studies are scarce and there is no one on Mexican Pacific reef echinoderms (MPRE). Therefore, the present study aims to analyze the distribution patterns and describe the spatial affinity of the reef echinoderms of the Mexican Pacific. For this purpose, records of species from two sources were obtained: i) literature, and, ii) databases. The information in the records corresponds to the period 1940-2016; with which a list of 75 valid species of reef echinoderms was generated for the Mexican Pacific region. For the analysis of quantitative biogeography four spatial scales were defined: i) localities ii) operational geographical units (OGU) of 0.5 °, iii) OGU of 1 ° and, iv) previously established biogeographical ecoregions. From a distance matrix generated for each scale, a clustering agglomerative dendrogram was obtained by the UPGMA method and a principal coordinates analysis (PCoA). Simultaneously, qualitative species change was estimated using the Wilson & Shmida´s beta diversity index, between each pair of geographic units along the latitudinal gradient. To determine if the distribution of the MPREs was consistent among echinoderms, the distribution between the classes was compared with Mantel tests on each scale. From OGU of 0.5 ° and 1 °, the number of species and the taxonomic discrepancy (Δ+) were estimated. To describe the latitudinal pattern, two linear regressions were performed for each spatial scale, one for species richness and another for Δ+ with respect to the latitudinal gradient. The spatial distribution patterns obtained were tested through a multiple regression analysis, comparing them against the latitude, longitude and sea surface temperature. Four biogeographic regions were described in which the MPRE were distributed: i) Pacífico tropical mexicano, ii) Archipiélago de Revillagigedo, iii) Golfo de California, iv) Costa Occidental de la Península de Baja California. According to the results, the number of species increases southward bound. The selected variables were able to predict the number of species up to 19%, without any of these being significantly associated with wealth. Finally, the taxonomic discrepancy analysis showed that the taxonomic diversity of the reef echinoderms stops increasing with few species,

Oct 2018

Porcellanasteridae is a group of starfish that live in the deep ocean around the world. The type species of this family, Porcellanaster ceruleus Wyville Thomson, 1878, is cosmopolitan as well as polymorphic. The first record of its occurrence in the South China Sea is reported in this paper. One specimen was caught in the South China Sea on June 6, 2015 by trawl and identified to be a P. ceruleus. The morphological characteristics of this specimen are described and detailed pictures are provided. The discovery of this specimen further expands the distribution of P. ceruleus in the Pacific Ocean. The world distribution records of P. ceruleus and its synonymic species are reviewed in this paper.

The Antarctic Circumpolar Current isolates and connects: Structured circumpolarity in the sea star Glabraster antarctica

Article

Full-text available

Oct 2018

Aim The Antarctic Circumpolar Current (ACC) connects benthic populations by transporting larvae around the continent, but also isolates faunas north and south of the Antarctic Convergence. We test circumpolar panmixia and dispersal across the Antarctic Convergence barrier in the benthic sea star Glabraster antarctica. Location The Southern Ocean and south Atlantic Ocean, with comprehensive sampling including the Magellanic region, Scotia Arc, Antarctic Peninsula, Ross Sea, and East Antarctica. Methods The cytochrome c oxidase subunit I (COI) gene (n = 285) and the internal transcribed spacer region 2 (ITS2; n = 33) were sequenced. We calculated haplotype networks for each genetic marker and estimated population connectivity and the geographic distribution of genetic structure using ΦST for COI data. Results Glabraster antarctica is a single circum‐Antarctic species with instances of gene flow between distant locations. Despite the homogenizing potential of the ACC, population structure is high (ΦST = 0.5236), and some subpopulations are genetically isolated. Genetic breaks in the Magellanic region do not align with the Antarctic Convergence, in contrast with prior studies. Connectivity patterns in East Antarctic sites are not uniform, with some regional isolation and some surprising affinities to the distant Magellanic and Scotia Arc regions. Main conclusions Despite gene flow over extraordinary distances, there is strong phylogeographic structuring and genetic barriers evident between geographically proximate regions (e.g., Shag Rocks and South Georgia). Circumpolar panmixia is rejected, although some subpopulations show a circumpolar distribution. Stepping‐stone dispersal occurs within the Scotia Arc but does not appear to facilitate connectivity across the Antarctic Convergence. The patterns of genetic connectivity in Antarctica are complex and should be considered in protected area planning for Antarctica.

Dec 2011

The aim of this work is to present three new shallow water (4 - >50 m) records of asteroids (Echinodermata: Asteroidea) for the Peruvian fauna: Astropecten regalis Gray, 1840, Paulia horrida Gray 1840 and Meyenaster gelatinosus (Meyen, 1834). Astropecten regalis geographical distribution is known that ranges from Gulf of California to Panama, this discovery extends its distribution to Mancora, Peru. Paulia horrida is known from Baja California to Isla Cocos, Costa Rica, and this record extends its southern distribution limit to Punta Sal, Peru. Meyenaster gelatinosus was considered endemic to Chilean waters, however, this record confirm its presence in Peru extending its northern distribution limit to San Juan de Marcona, Peru. Morphological and habitat information on this four species is provided, together with live pictures.

First Records of the Brooding Astropectinid Starfish Trophodiscus almus (Echinodermata : Asteroidea) from Japan, with Reference to Its Zoogeographical Significance

Article

May 2002

Yoichi Kogure

An astropectinid starfish with a unique habit of brooding, Trophodiscus almus Fisher, 1917, has been previously reported to be endemic to the northern part of the Sea of Okhotsk. Recently 11 specimens of this species were obtained from the northern Sea of Japan at depths of 290-295 m off Ajigasawa in Aomori Prefecture, far to the south of the Sea of Okhotsk, and 18 specimens from off Kushiro, Hokkaido, in the Pacific Ocean at depths of 153-252 m. These occurrences of T. almus represent the first records from Japanese waters, and the Sea of Japan is a new southern range limit. A detailed redescription of the species is provided along with color photographs and scanning electron micrographs. The distribution patterns of starfishes known from the Sea of Okhotsk are reviewed in relation to the zoogeographical significance of T. almus.

Jan 2013

The genus Heliaster (Gray, 1840) includes a remarkable group of seven species that inhabit rocky intertidal and shallow subtidal habitats and are morphologically characterized by a large disc and a large number of rays. Geographically, the genus is restricted along the tropical, subtropical, and temperate coasts of the Eastern Pacific. Four species inhabit mainland littoral sites: Heliaster helianthus (Lamarck, 1816) in the tropical, subtropical and temperate west coasts of South America; Heliaster polybranchius H. L. CLARK, 1907, in the tropical coast of Peru; Heliaster kubiniji XANTUS, 1860 and Heliaster microbrachius Xantus, 1860, in the west coasts of Mexico and central America. Three species inhabit off shore archipelagos: Heliaster canopus Perrier, 1875, in Chile's Juan Fernández Archipelago; and Heliaster solaris A. H. Clark, 1920, and Heliaster cumingii (Gray, 1840) in the Galápagos Archipelago of Ecuador (see J. E. Gray 1840, H. L. Clark 1907, A. H. Clark 1920, A. M.

A review of high-latitude Goniasteridae south of 50°S is presented, including a key to species, figures and taxonomic descriptions of all species with a brief taxonomic summary for all genera. Nineteen species in 11 genera are reviewed. Era-tosaster jenae nov. gen and sp., Chitonaster trangae nov. sp., and Pillsburiaster calvus nov. sp. are described. Several taxa, including Chitonaster, have not been reviewed since their initial description and revision of the group has clarified taxonomic boundaries between species. The genus Pentoplia is a junior synonym of Chitonaster. Rarely encountered species, synonyms, and range extensions are reported for multiple species.

Starfish: Biology and ecology of the Asteroidea

Article

Jan 2013

John Miller Lawrence

Among the most fascinating animals in the world's oceans are the more than 2,000 species of starfish. Called "Asteroids" by scientists who study them (after their taxonomic name, Asteroidea)-or sea stars in some parts of the world-starfish are easily recognized because of their star-like form. Starfish is a comprehensive volume devoted to the integrative and comparative biology and ecology of starfish. Written by the world's leading experts on starfish, the integrative section covers topics such as reproduction, developmental biology and ecology, larval ecology, and the ecological role of starfish as a group. The comparative section considers the biology and ecology of important species such as Acanthaster planci, Heliaster helianthoides, Asterias amurensis, and Pisaster ochraceus. Replete with detailed, scientifically accurate illustrations and the latest research findings, Starfish examines the important role of these invertebrates in the marine environment, a topic of great interest because of their impact on the food web. As major predators that are able to evert their stomach and wrap it around their prey, starfish can have a significant impact on commercial fisheries. Starfish are of interest not only to echinoderm specialists but also to marine biologists and invertebrate zoologists in general and, increasingly, to the medical community. A starfish's ability to regenerate body parts is almost unequalled in the animal world, making them ideal models for basic science studies on the topic. Contributors: Charles D. Amsler, Bill J.

Lower Cretaceous (Albian) Asteroidea (Echinodermata) from Tepexi de Rodriguez, Puebla, Mexico

Article

Full-text available

Jun 2015

Seven asteroids are described from the Tlayua quarries (18° 35´ N - 97° 56´ W), recovered from the Middle Member of the Tlayua Formation. Tlayua quarries are 94 km southeast of Puebla and 2 km northeast of the town of Tepexi de Rodriguez in the Eastern part of central Mexico. The Middle Member is fossiliferous and composed mainly of a micritic lithographic limestone with layers having packs that consist of as much as 30 % hematite. The fossils are confined to these iron rich layers. These Middle Member are about 28 m thick. Due to the abundance, variety and conservation of its paleobiota, the Tlayua quarry is one of the most important fossiliferous localities from North America’s Cretaceous. About 5 000 samples of invertebrate and vertebrate fossils have been collected from this locality and have been studied. The seven specimens belong to the Cretaceous strata and are believed to be of Lower Cretaceous (Albian) age. The asteroids described are referred to the genus Astropecten, Plutonaster, Tamaria and Echinaster. This is the first report of Cretaceous asteroids for Mexico.

Stony corals, echinoderms and fish associated to coral communities and reefs from the Parque Nacional Huatulco, Southern Mexican Pacific

Article

Full-text available

Dec 2014

As a result of literature review, collection visit and field work we compile the systematic list of stony corals (10 species), echinoderms (32 species) and fish (150 species) that inhabit the Parque Nacional Huatulco (PNH). The number of reported species (191) represents an increase similar to 66.9% respect to previous studies. Respect to other Protected Areas (PA) in Mexico, the PNH harbors larger species richness than PA located in the Central Mexican Pacific, but below the richness recorded in PA located in the Caribbean and the Gulf of Mexico. Although the PNH harbors a relatively large number of species, the taxonomic diversity of stony corals and fish is lower than expected since only protects taxonomically related species, therefore is taxonomically impoverished regarding the tropical eastern Pacific fauna. The management of the PNH is strategic for the maintenance of the shallow marine communities from western Mexico, since it guarantees the entrance of species from Central America to the Mexican Pacific, but also because the PNH is the only protected reservoir of species from the Panamic Province in the entire Mexican Pacific.

Arm Deflation in the Rare Thorny Sea Star, Poraniopsis inflatus (Asteroidea: Poraniidae), A Defensive Response to other Sea Stars?

Article

Full-text available

Jul 2010
Can Field Nat

The Thorny Sea Star, Poraniopsis inflatus, is rare in the Northeastern Pacific. It lacks pedicellariae or other overt defenses for protection against other predatory sea stars. During an earlier study, a P. inflatus confronted by an asteroid-eating sea star was observed to exhibit a possible defensive reaction: "arm deflation." It was 15 years before another P. inflatus specimen could be obtained and that hypothesis confirmed by testing with individuals of 18 other sea-star species. Contact with individuals of four predatory sea-stars, Asterina miniata, Crossaster papposus, Solaster dawsoni, and Pycnopodia helianthoides, elicited the reaction in the P. inflatus. The specimen collapsed ("deflated") an arm closest to the predatory star, possibly by expelling coelomic fluid, exposing more of its embedded thorns (hence its common name) which may discourage other sea stars from attempting to eat it.
