Abstract

The class Crinoidea is recorded for the first time in the Colombian Pacific Ocean based on 407 specimens collected on soft bottoms in eight stations at depths ranging from 350 to 934 m. Sampling was carried out using trawls with an epibenthic net (9 × 1 m opening, 2.5 knots for 10 min) during the Tumaco Offshore project (2012–2013). The specimens represent three comatulid crinoids, two of which were identified as Florometra tanneri (Hartlaub, 1895) and Psathyrometra fragilis (A.H. Clark, 1907); and one to the family level (Antedonidae). Taxonomic descriptions with images of the specimens, distribution, and comments of the two species collected in the Colombian Pacific are presented and discussed.
