Despite its 2000 km long shoreline, to date less than 50 sponge species have been reported from the entire Peruvian coast. A large collecting effort targeting marine sponges was undertaken between 2007 and 2009, yielding a comprehensive collection of nearly 900 samples, whose taxonomic study is underway. Three new species of Hymedesmiidae are prese...

This dataset contains information on 231 specimens of 80 species of the Demospongiae class, including their distribution in coral reefs in the Southern Gulf of Mexico, and their...
Article
Antarctic sponges were mainly studied from trawling or dredging (shallow and deep water) during pioneering oceanographic expeditions carried out since the late 19th century. More recently, sponge collections by SCUBA diving have allowed the detection of species in more cryptic habitats such as rocky walls. In this study, we analyzed Antarctic spong...

Since the 19th century the deep-sea sponges from Brazil have been studied and many of them are still being discovered. This study describes five species of tetillid sponges from deep waters of the Brazilian economic exclusive zone; three are new, one is a new occurrence, and another is a known species which is here analyzed. The new species found a...

El nivel de aislamiento de Antártica, influenciado por la Corriente Circumpolar Antártica permite que exista alto grado de endemismo y riqueza de especies de esponjas. Actualmente se estiman 400 especies, distribuidas en 3 clases, Demospongiae, Calcarea y Hexactinellida, siendo más abundantes las demosponjas (350 especies aproximadamente). Las espo...
Article
Several sponges from American Samoa, collected by the Coral Reef Research Foundation, Republic of Palau, were tentatively identified by one of us as Acanthotetilla cf seychellensis (Thomas 1973), due to the possession of relatively small acanthose oxeas, compared to those of other species of the genus Acanthotetilla Burton 1959. These sponges were...
Article
Our ongoing studies of the Chilean sponge fauna revealed four new species of Lissodendoryx (Ectyodoryx) that are described here, including three from the fjord’s region (< 30 m depth, L.(E.) ballena sp. nov., L. (E.) corrugata sp. nov., L. (E.) coloanensis sp. nov.), and one from the deep waters off Diego Ramírez Archipelago (ca. 2000 m, L. (E.) di...
Article
The recent description of Indonesian and Brazilian species of Acanthotetilla motivated the onset of a phylogenic and biogeographic revision of this taxon, to figure whether it had an Atlantic or an Indo-Pacific origin, and whether a Tethyan or southern African route might have been followed. A datamatrix with 27 morphological characters and 63 char...

In this paper we describe three new species of Tetilla from stretches of the coast of Bahia, northeastern Brazil, all collected in shallow waters and soft bottoms. Tetilla pentatriaena sp. nov. is distinct from other species of the genus by the unique possession of five categories of triaenes: two of protriaenes and three of anatriaenes. Tetilla mu...

Following URIZ (2002), the Thrombidae are “irregular, massive or encrusting, creepingstoloniferous sponges, with diplodal aquiferous system and cortex barely discernible. Without monaxonid spicules. The megascleres are small spiny triaenes of different types, with simple, bifurcate or trifurcate clads (i.e., plagio-, dicho-, and trichotriaenes), on...

... En Chile, los estudios han sido predominante orientados al conocimiento de la diversidad (riqueza y distribución) de especies de los fiordos (Thiele, 1905;Hajdu et al., 2013;Fernández et al., 2021). Actualmente, se conocen 190 especies, incluyendo las clases Calcarea (n = 15), Demospongiae (n = 160) y Hexactinellida (n = 15); y entre estas, 140 han sido registradas para los fiordos (Bertolino et al., 2020;Fernández et al., 2021). ...

Pablo Alberto Hernández-Solis 1 , Diana Ugalde 2 , Lorena Violeta León-Deniz 1 , Víctor Eduardo Gómez-Bretón 1 , Candita Mariana Eúan-Canul 1 INTRODUCCIÓN Las esponjas (phylum Porifera) son un grupo diverso de animales bentónicos con gran importancia ecológica. Los registros de especies de esponjas para Yucatán se han enfocado principalmente en sistemas arrecifales (Alacranes y Bajos de Sisal), dejando a los ecosistemas costeros y lagunares poco estudiados (Ugalde et al., 2015(Ugalde et al., , 2021Pech-Puch et al., 2020). Por lo que este trabajo se enfoca en describir el primer listado taxonómico de esponjas de hábitats costeros de Yucatán. ...
... (order Haplosclerida, family Chalinidae), 15 individuals of H. torquata (order Suberitida, family Halichondriida), and five individuals of I. kerguelenensis (order Poecilosclerida, family Isodictyidae) were selected for the analyses. All three are common sponge species in this study area (Fernandez et al., 2020). Sponge samples were collected by SCUBA divers between 10 and 20 m depth. ...
... The distribution of C. kuekenthali is similar to that of C. apion, ranging from the GoM to Brazil (Rützler & Smith 1992;Rützler et al. 2009;Hajdu et al. 2011;Muricy et al. 2011;Fernandez et al. 2018). However, C. kuekenthali is also known from deeper waters, down to 100 m in Brazil (Fernandez et al. 2018). ...
... Microacanthoxeas. Prior to this study, microacanthoxeas were known in only five out of 40 species of Cinachyrella worldwide; namely, Cinachyrella anatriaenilla Fernandez, Kelly & Bell 2017, Cinachyrella australiensis (Carter 1886, Cinachyrella cavernosa (Lamarck 1815) (re-described by Topsent 1931), Cinachyrella globulosa Desqueyroux- Faúndez & van Soest 1997 and Cinachyrella kuekenthali. Further, microacanthoxeas are also present in Levantiniella levantinensis (originally as Cinachyrella levantinensis), which is another tetillid sponge. ...
... The research of the KNR marine ecosystems is limited, and the sublittoral benthic communities and their ecological patterns are still almost unknown since only a few studies have been made in central Patagonia (e.g., Häussermann and Försterra, 2007;Quiroga et al., 2012;Försterrra et al., 2017;Friedlander et al., 2021). In contrast, most studies about the ecology of sublittoral benthic communities of the CPFC have been carried out mainly in the north (e.g., Häussermann et al., 2013;Zapata-Hernańdez et al., 2016;Betti et al., 2017;Betti et al., 2021;Villalobos et al., 2021) and south (e.g., Gerdes and Montiel, 1999;Montiel et al., 2005;Rıós et al., 2007;Montiel et al., 2011). ...
... Despite published reports on sponge distribution in the Pacific Ocean, knowledge gaps still exist in the eastern Pacific, and especially along the coast of Ecuador, where descriptive studies have rarely been conducted (Miloslavich et al. 2011). A recent increase in taxonomic effort in this large area started in Chile (Hajdu et al. 2006;Azevedo et al. 2009;Willenz et al. 2009;Hajdu et al. 2013;Fernandez et al. 2016;Costa et al. 2020), and more recently expanded to the Peruvian coast (Aguirre et al. 2011;Azevedo et al. 2015;Hajdu et al. 2015;Cóndor-Luján et al. 2019;Recinos et al. 2020). This collective effort has unveiled a high diversity and abundance of sponges in shallow south-eastern Pacific waters. ...
... The main macroscale, shallowwater, distribution patterns of Brazilian marine sponges are the Tropical West Atlantic and endemic. The first reflects the large number of species currently shared with the Caribbean region (e.g., Van Soest and Hajdu 1997), and the second denotes a particular evolutionary history, where distinct barriers were expressed at different times, starting with the collapse of Gondwana and early opening of the Atlantic in the Cretaceous (Fernandez et al. 2012). At least 108 species of marine sponges have already been identified from Brazilian oceanic islands, but many species still await detailed taxonomic study in scientific collections. ...
... Over 10000 living species have al ready been descr ibed, which present a varied range in size, shape, color and ecological habitats (Muricy and Hajdu, 2006). Only six species out of 393 which inhabit Brazilian coast (Mur icy et al. 2011) were recorded to Camamu Bay at Bahia State (Peixinho et al., 2005;Menegola et al. 2009;Fernandez, 2011;Menegola et al., 2011). However, Mothes et al. (2006) estimate that hundreds of species are still to be discovered in Brazil. ...
