In this paper, we compile all existent studies including the presence of Crustacea in Bahia Malaga. We also compile available information on crustacean material deposited in different zoological collections. The literature revision and visits to museum collections were complemented with field sampling and observations during field work carried out by Universidad del Valle and the BIOMALAGA project coordinated by Invemar, Univalle and Inciva (Invemar 2006).
