“…It is known that species of Echinometra maintain erosion levels in the areas they inhabit and are commonly found in limestone reefs (Hendler et al, 1995). Similarly, other authors have reported E. lucunter in environments closely related to rocky substrates, and it is indicated as common and an abundant species in several places throughout the Caribbean and other areas towards the northeastern coast of Brazil (Hendler et al, 1995;Bolaños et al, 2005;Alvarado et al, 2008, Gaitán Espitia, 2008Gondim et al, 2018;McClanahan & Muthiga, 2020).…”

Echinoderms are a major group of marine invertebrates that often play integral roles within the marine ecosystem. Studies about their occurrence, abundance, and distribution in Venezuela are focused in the central-eastern coasts; hence the aim of this study is to describe the echinoderm community in the north-western coast of the Gulf of Venezuela. Samples were collected from three sites in the Venezuelan Guajira Peninsula (Castilletes, Porshoure, and Kazuzain) where patchy coral reefs and seagrass meadows are abundant. According to the substrate, two methods were performed using quantitative (1 m² quadrates), and qualitative free-diving observations. All organisms were counted and identified to the lowest possible taxonomic level; finally, diversity (Shannon diversity index), richness (number of species), and dominance in the different sampled substrates were recorded. The updated list of echinoderms of the Gulf of Venezuela reported in this research, includes 20 genera, 15 families, 10 orders, four classes, and 28 species. The richest class was Ophiuroidea, with 18 species, followed by Asteroidea, Echinoidea and Holothuroidea, with three species each. Castilletes was the sampling site with the higher number of species (18 species), followed by Porshoure (15 species), and lastly Kazuzain (12 species). Our observations indicate that the number of species and abundance were higher when found in coral reefs (21 species, 80.69% of the total collected individuals) in contrast to the species found in seagrass beds (16 species, 19.31% of the total of individuals collected). This updated list of echinoderms represents 11.54% of the total diversity of the phylum in the marine areas from the coast of Venezuela; it is suggested that this percentage is greatly influenced by the differences of habitats and substrates alongside the north-western coast in the Gulf of Venezuela.

Los equinoideos comprenden uno de los grupos más influyentes en los ecosistemas arrecifales y litorales rocosos, debido a su importancia en las redes tróficas y reciclado de materia orgánica. En el Caribe colombiano existe un vacío de información sobre la ecología de estos organismos. La mayoría de los estudios se han centrado en la realización de inventarios y notas taxonómica, con el fin de estudiar la diversidad, la densidad poblacional y la distribución espacial de equinoideos regulares, en Isla Fuerte, Colombia. Se realizaron siete salidas de campo en Punta El Inglés, Latal y San Diego, entre noviembre de 2018 y septiembre de 2019. En cada localidad se realizaron censos visuales, aplicando la metodología de transecto lineal en banda (10 x 2 m). Se registraron 4.061 individuos representativo de seis especies, cinco géneros y cuatro familias. La especie que presentó mayores densidades fue Echinometra lucunter y, la de menor, Lytechinus variegatus. La riqueza de especies fue la misma para las tres localidades; sin embargo, Punta El Inglés presentó mayor diversidad, uniformidad y distintividad taxonómica promedio. El análisis de similitud de Bray-Curtis muestra una asociación entre San Diego y El Latal, mientras que Punta El Inglés forma una agrupación independiente. Los resultados de esta investigación representan una línea base para Isla Fuerte y puede ayudar a los gestores ambientales para sustentar herramientas y estrategias de manejo en este grupo de invertebrados
