Objectives:

Characterize the amphipods collected in esophageal lavages of the green turtle Chelonia mydas (Linnaeus, 1758).

Scope:

Increase the characterization of diversity of a poorly known group, but of great importance in benthic environments, in Colombia.

Methodology:

Amphipods were collected from esophageal lavages carried out on 77 green turtles between February and December 2012 at Gorgona Island, Colombian Pacific.

Main results:

We report the occurrence of the amphipod Hyachelia tortugae Barnard, 1967, a species that lives exclusively as an epibiont of sea turtles, for the first time for the Colombian Pacific. Three H. tortugae individuals occurred in two of the analyzed turtles. The hyperiid amphipods Paralycaea gracilis Claus, 1879, Schizoscelus ornatus Claus, 1879, and Parascelus sp. were also collected in the esophageal contents of the turtles.

Conclusions:

This study highlights that systematic studies should be carried out to characterize the associated fauna in sea turtles in the Colombian Pacific.
