The fauna of unstalked crinoids (Echinodermata) near Santa Marta, Colombia, is unique in the tropical western Atlantic in both species diversity and population size. Seven species have been observed at depths above 36 m. A field key to these species is presented. The distribution and abundance of these species in the Santa Marta region suggest that the ridiest populations are located on the leeward sides of headlands and islands. Local upwelling in the region may be partly responsible for the richness of the crinoid fauna.
