Echinoderms are a marine invertebrate group with important ecological functions in the ocean; they are the source of bioactive compounds, and some species are important for fisheries and aquaculture. Their study in the Colombian Caribbean has focused on taxonomic and ecological aspects and they are a well-documented group of invertebrates. However, small-scale studies of the group are required given the geomorphological and oceanographic diversity along the entire Colombian coastline. The Magdalena River runoff strongly influences the coastal ecosystems of the Department of Atlántico, which has the shortest continental shoreline with only 72 km. The benthic fauna in its surroundings is the biotic component receiving the influence of this river directly, but it has not been the object of deep taxonomic and ecological studies. Field echinoderm surveys were conducted at several sites from 2004 to 2019. Observations and direct collections were carried out from 0 to 5 m depth. We identified four classes, seven orders, eight families, ten genera, and 16 species. Thirteen of these species were first records for Atlántico: Luidia senegalensis, Astropecten articulatus, Amphiodia riisei, Amphiodia trychna, Echinometra lucunter lucunter, Encope michelini, Leodia sexiesperforata, Mellita quinquiesperforata, Isostichopus badionotus, Isostichopus sp., Holothuria grisea, Holothuria glaberrima, and Holothuria princeps. The most frequently observed species were M. quinquiesperforata and H. glaberrima. We provide the local geographic distribution, illustrations, and remarks on each species. This study attempts to close gaps regarding the knowledge of the distribution of marine invertebrates in the Colombian Caribbean Sea.

Holothuria grisea es una especie que se distribuye a lo largo del Caribe y la cual ha sido extraída ilegalmente en Colombia, lo que se agrava aún más por el desconocimiento de su biología y ecología. Este estudio, evaluó algunos aspectos de la biología reproductiva de H. grisea en la Bahía de Cispatá, a partir de organismos recolectados entre abril y noviembre de 2015. Se calculó el índice gonadal y la determinación de los estadios gametógenicos con base en métodos histológicos clásicos. En el presente estudio, fueron analizados 80 individuos, de los cuales el 47.5% fueron machos, 45% hembras y el 7.5% no presentaron tejido gonadal. Las observaciones microscópicas e histológicas permitieron identificar tres estadios gonadales para la especie: crecimiento, madurez y post-desove. Se evidenció que este holotúrido dioico presenta una proporción sexual 1:1, con un ciclo de reproducción continúo presentando tres picos reproductivos en los ocho meses estudiados. Por último, la talla de primera madurez gonadal para la especie fue 13.5 cm. La información obtenida en este trabajo podría ser de gran utilidad a futuro desde el punto de vista de la sostenibilidad de este recurso y de la implementación de programas prácticos de gestión.

Herein, we describe the first-ever identification of Amorphinopsis atlantica in the Iguape Bay (Bahia, Brazil). The bay, where fish and shellfish harvesting has been practiced for centuries, is part of the Paraguaçu River estuary, the main tributary of Todos-os-Santos Bay. Massive encrusting specimens of sponge species growing on three different types of substrates were collected manually in the intertidal zone of a mangrove in an estuary; despite being initially described in Brazilian subtropical coastal waters. There are records for A. atlantica in the southeastern states of Rio de Janeiro, São Paulo, and northeastern states of Pernambuco, Paraíba (Brazil), Falcón (Venezuela), Campeche and Vera Cruz (Mexico), in the department of Córdoba (Colombia), in the Hidden Creek district (Belize) and the Atlantic coast of Costa Rica. In the collection area, the construction of a dam in the tidal river and the subsequent hydroelectric power have changed the estuary dynamics to a threshold condition expected to be tolerated by new colonizers organisms. In this unpredictable scenario, Amorphinopsis atlantica has found a new habitat for more than 15 years. Local people have alleged that the sponge may cause recurring skin rashes, but this has not yet been confirmed. Monitoring and study on the distribution and abundance of the species and a medical survey may clarify the role of the sponge on the skin dermatitis complained by the local population.
