Sea cucumbers are the second most diverse class among echinoderms. They are characterized by an elongated body and dermal ossicles in the body wall. Among the included groups in that class, the order Holothuriida encompasses many species of commercial interest. Faced with the threats of biodiversity loss resulting from the climate crisis and the advancement of cities, this study provides an overview of recent research involving the Holothuriida of the Brazilian Coast. Searches were carried out in the main periodical databases, using appropriate keywords, targeting publications on the subject in the period between 2000 and 2023. In total, 69 publications were found, most of them corresponding to scientific articles in international journals. Most of the studies come from the Northeast region in Brazil (56.52%). Regarding lines of research, those involving taxonomy and molecular analysis were the most prevalent. Over these 20 years, seven species constituted new occurrences. Of note are the studies focused on Holothuria (Halodeima) grisea, which makes up 39.13% of papers. Despite progress, little is known about morphological variations, genetic distance between populations, population densities, and on reproductive biology of species. Brazil has a vast, heterogeneous coastal area, with unique characteristics to which the species are adapted. The findings reinforce the importance to expand studies aiming on knowing the biodiversity, reproductive biology, and population densities of species. Such data are essential for the creation of public policies aimed at the conservation of species of Holothuriida and their habitats.

“…Diversity information of deep-sea echinoderm fauna through recent research is scarce (Pawson, 1982;Stöhr and Segonzac, 2005;Mecho et al, 2014;Moles et al, 2015;Calero et al, 2017;Mironov et al, 2018;Setyastuti and Wirawati, 2018;Stöhr and O'Hara, 2021). Strong progress has been made, especially for Colombia, Chile, Brazil, Argentina and Mexico (González et al, 2002;Borrero-Pérez et al, 2003;Benavides-Serrato and Borrero-Pérez, 2010;Campos et al, 2010;Manso, 2010;Massin and Hendrickx, 2011;Borrero-Pérez et al, 2012;Hendrickx et al, 2014;Solís-Marín et al, 2014;Martínez et al, 2014;Martínez et al, 2015;Martínez, 2016;Conejeros-Vargas et al, 2017;Martinez and Penchaszadeh, 2017;Martínez et al, 2017, Rivadeneira et al, 2017Luna-Cruz and Hendrickx, 2018;Borrero-Pérez et al, 2019;Flores et al, 2019;Pertossi et al, 2019;Martínez et al, 2019;Borrero-Pérez et al, 2020;Martinez et al, 2020;Rivadeneira et al, 2020;Luna-Cruz and Hendrickx, 2020;Catalán et al, 2020;Luna-Cruz and Hendrickx, 2021;Flores et al, 2021).…”

Diversity of Deep-Sea Echinoderms From Costa Rica

Echinoderms are a highly diverse group and one of the most conspicuous in the deep sea, playing ecological key roles. We present a review about the history of expeditions and studies on deep-sea echinoderms in Costa Rica, including an updated list of species. We used literature and information gathered from the databases of the California Academy of Sciences, the Benthic Invertebrate Collection of the Scripps Institution of Oceanography, the National Museum of Natural History, the Museum of Comparative Zoology and the Museo de Zoología from the Universidad de Costa Rica. A total of 124 taxa (75 confirmed species) have been collected from the Costa Rican deep sea, 112 found in the Pacific Ocean, 13 in the Caribbean Sea, and one species shared between the two basins. We report 22 new records for the Eastern Tropical Pacific, 46 for Central American waters, and 58 for Costa Rica. The most specious group was Ophiuroidea with 37 taxa, followed by Holothuroidea (34 taxa), Asteroidea (23 taxa), Echinoidea (17 taxa), and Crinoidea (11 taxa). The highest number of species (64) was found between 800 m and 1200 m depth. Only two species were found deeper than 3200 m. Further efforts on identification will be required for a better comprehension of the diversity of deep-sea echinoderms. Limited research has been done regarding the biology and ecology of deep-sea echinoderms in Costa Rica, so additional approaches will be necessary to understand their ecological functions.

“…Remotely operated vehicles have the advantage of extending dive time and depth whilst creating a permanent record, and facilitating resampling (Riegl et al, 2001;Lam et al, 2006). Marine surveying with an ROV has been done on both a mesoand broad scale (Stein et al, 1992;Pacunski et al, 2008;Campos et al, 2009;Cánovas-Molina et al, 2016), and the initial costs of purchasing and operating ROVs for smaller-scale projects are now feasible (Pacunski et al, 2008;Azis et al, 2012). Remotely operated vehicles are also versatile and fairly easy to operate (Leujak and Ormond, 2007;Pacunski et al, 2008).…”
