First record of Echinothrix calamaris (Echinoidea: Diadematidae) in the Colombian Pacific

摘要

The occurrence of Echinothrix calamaris Pallas, 1774 is reported for the first time in Colombia. Three specimens of Echinothrix calamaris were collected in two fringing reefs (La Azufrada and Playa Blanca) at Gorgona Island. The specimens now lie in the Echinoderm Collection of the Marine Biology Section at Universidad del Valle (Cali, Colombia). This finding constitutes a range extension towards the Tropical Eastern Pacific, with only one previous record from Cocos Island. The list of Echinoids from the Pacific coast of Colombia now comprises 30 species.
