Article
Full-text available
There are numerous and important coral reefs in the Mexican Pacific, but scarce studies of brittle stars conducted in these ecosystems. In this regard, this work provides the first annotated checklist of brittle stars associated with coral communities and reefs in the Mexican Pacific and an illustrated key to identify the species. We also provide t...

Full-text available
Despite the important effort of knowing the Ophiuroidea diversity in the Mexican Pacific, some mistakes in the taxonomic nomenclature have pervaded through time. In order to clarify the latter, a checklist based on literature review of brittle stars from the Mexican Pacific is provided. We reviewed a total of 105 references that in total summarized...
Article
Studies on size changes of Ophiuroidea are limited, despite their importance and implications in taxonomy, phylogenetics, ecology and distribution. These studies have traditionally been based on descriptive size series seldom integrating quantitative analyses to assess the morphological variability of species, despite their potential use to study s...
Article
Full-text available
Introduction: The echinoderms from the Central Mexican Pacific are of high scientific interest and, prior to this present work, there was a lack of basic information that included incomplete checklists with inconsistencies in systematics and spatial distribution. Objective: To provide a historical review, and an updated checklist with a more comple...
Article
Full-text available
The widespread Ophioderma hendleri sp. nov., from the Eastern Tropical Pacific (Mexico to Colombia) is distinguished from its congeners by having radial shields covered by granules, naked adoral shields, up to 11 arm spines, and by its brown and beige coloration. Ophioderma hendleri sp. nov. belongs to the group of species with naked adoral shields...
Article
Full-text available
Despite the high relevance of echinoderms in the Southern Mexican Pacific coral reef systems, there is no detailed analysis of their regional diversity. Based on records from field surveys and literature, this work analyzed for the first time the echinoderm species composition in coral reef systems in the Southern Mexican Pacific, evaluating their...
Article
We describe a new species of ophiodermatid brittle star from the Eastern Pacific: Ophioderma occultum sp. nov. This species has been mistakenly recorded since 1899 as a colour phase of one of its congeners, Ophioderma panamense. However, the integrative use of morphological and molecular data, and comparison with type material of other Eastern Paci...
Article
Full-text available
Introduction: Chamela bay is located in the central portion of the coast from the Jalisco state, Mexico and is an important protected natural area. Despite this, the study of echinoderms in the area is incipient. Objective: To provide an updated checklist, descriptions of the species and a taxonomic key of the ophiuroids from Chamela bay. Methods:...
Article
Full-text available
Introduction: The importance of holothuroids in marine ecosystems is related to their feeding activities, which have been little studied in the eastern Pacific. Objective: To describe the feeding habits of the sea cucumber Holothuria (Stauropora) fuscocinerea and their bioturbation potential in La Entrega reef, México. Methods: The population size...
Article
While the Ophiuroidea of Peruvian waters have long been studied, there exists inconsistencies regarding taxonomy and spatial distribution records. Based on literature review and museum records, we provide an updated checklist of the ophiuroids accompanied by the first geographical distribution analysis. Peruvian waters host 36 species of Ophiuroide...
Chapter
Full-text available
Shallow coral reefs worldwide occupy 1.2% of the world’s continental shelf area but support an estimated 35% of all known marine biodiversity. Nevertheless, our knowledge of reef-associated biodiversity in southern Mexican Pacific systems is scarce. Here, we synthesize the knowledge regarding the biodiversity of reef-associated organisms including...
Article
Full-text available
The Central Mexican Pacific is an oceanographic transitional region with complex habitats and important conservation areas, but knowledge of its Ophiuroidea fauna is limited. A total of 61 localities on a variety of substrata were sampled between 2008 and 2014 using different methodology techniques. Twenty-four species were collected and members of...
Article
Full-text available
Gorgonocephalid ophiuroids, or basket stars, reside in diverse ecosystems of all oceans, but there is limited information on their basic ecology worldwide; therefore, this study provides the first detailed numerical analysis published to date of the abundances and spatial distributions of gorgonocephalids from the eastern Pacific Ocean. We analysed...
Article
Full-text available
Knowledge about ophiuroids from Chiapas, Mexico, is still limited; only Diopederma daninana was previously recorded in the state. In order to contribute to the knowledge of their diversity in the region, ophiuroids were collected in four localities of Puerto Chiapas, in different substrata and at different depths. Three species were identified: Oph...
Article
Full-text available
The reef-associated echinoderm cryptofauna has received scarce attention notwithstanding its large-scale effects on reef community structures and ecosystem functioning world-wide. In the present study, a spatially hierarchical quantitative sampling protocol was designed to address Pocillopora damicornis-associated echinoderm diversity within and ac...
Article
Full-text available
We surveyed coral reefs communities before (September 2007–March 2009) and during (September 2009) the 2009–2010 El Niño event on the coast of Oaxaca, southern Mexican Pacific to evaluate community changes associated with the warming event. From May 2009 to December 2010, we recorded positive deviations from the historical in situ sea surface tempe...
Article
Full-text available
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 Mexic...
Article
Full-text available
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 fishes (150 species) that inhabit the Parque Nacional Huatulco (PNH). The number of reported species (191) represents an increase ~ 66.9% respect to previous studies. Respect to other Protected...

Full-text available
The basket star Gorgonocephalus eucnemis is a common ophiuroid resident of rocky bottoms and artificial substrata at depths of 8 to 1,850 m, and in the eastern Pacific is distributed from the Bering Sea to San Diego, USA. This paper presents a new record of this species obtained with a submersible at Guadalupe Island, Mexico (29.109768N, 2118.25417...
Article
Full-text available
An association between the scale-worm Malmgreniella cf. variegata and the ophiuroid Ophionereis annulata is reported for first time in the Mexican Pacific. The relationship was found in five localities across a total of 22 sites where O. annulata was collected. The polynoids collected were similar to the Western Atlantic scale-worm Malmgreniella va...

One specimen of the sea cucumber Euapta godeffroyi (Semper, 1868) is reported from La Entrega reef (15°44´34´´ N, 96°07´35´´ W), Southern Mexican Pacific. The specimen was observed feeding late at night, supporting the nocturnal habits of this species which is a deposit feeder. No specimens of this species had been previously reported for the area...
Article
Full-text available
New records of ophiuroids from localities at Zihuatanejo, Guerrero and Puerto Escondido, Oaxaca in the Mexican Pacific are presented. Based on specimens collected on diverse substrata, 12 species were identified; Ophiocoma alexandri Lyman, 1860 and Ophiothela mirabilis (Verrill, 1867) being the most widely distributed. The larger number of recorded...
Article
Full-text available
Sedimentation on reef communities at Bahías de Huatulco, Oaxaca, Mexico. Although coral reef sedimentation is important because it modifies processes like symbioses, reproduction, recruitment and coral growth, Mexican Pacific studies are lacking. On this regard, spatio-temporal variations in sedimentation rate were investigated in six coral reef co...
