QUIROS-RODRIGUEZ, Jorge Alexander. Echinoderms in Shallow-Bottom from Ahumadera Sector, Cispatá Bay, Cordoba, Colombian Caribbean. Acta biol.Colomb. [online]. 2015, vol.20, n.1, pp.101-108. ISSN 0120-548X.

This study represents a report of the echinoderm fauna found in shallow waters of the sector La Ahumadera, Cispatá Bay, Colombian Caribbean. The area is formed by a plain substrate type soft sand-mud colonized by sponges in punta Terraplén and sandy with seagrass (Thalassia testudinum), macroalgae and sponges in punta Robalo. Were identified ten species of echinoderms belonging to four classes (Asteroidea, Ophiuroidea, Echinoidea and Holothuroidea), distributed in eight families and nine genera. The number of taxa identified corresponds to 4.1% of the species recorded for the Colombian Caribbean, and shows the representation of species of echinoderms in this sector. The most abundant species in punta Robalo were Encope michelini (24.3%) and Ophiothrix angulata, while in punta Terraplén were O. angulata (36.7%) and Ophiactis savignyi (16.5%). Higher richness (S= 9), diversity (H'= 2.64) and evenness (U= 0.92) were found in punta Robalo compared to values from Terraplén (S= 6, H'= 2.39 and U= 0.83). Both stations showed a similarity index (Is) of 0.66.Among the species identified, the following are new records for the department of Córdoba: Holothuria floridana, Encope michelini and Mellita quinquiesperforata.

Keywords : Cispata Bay; echinoderms; shallow-bottom; Thalassia testudinum.
