Euapta godeffroyi(Holothuroidea: Synaptidae): Filling the distribution gap between Mexico and Costa Rica, eastern tropical Pacific

One specimen of the sea cucumber Euapta godeffroyi (Semper, 1868) is reported from La Entrega reef (15 degrees 44 ' 34 '' N, 96 degrees 07 ' 35 '' W), Southern Mexican Pacific. The specimen was observed feeding late at night, supporting the nocturnal habits of this species which is a deposit feeder. No specimens of this species had been previously reported for the area extending from Isla Isabel, Mexico (21 degrees 51 ' 43 '' N, 105 degrees 53 ' 28 '' W) to Golfito, Costa Rica (8 degrees 37 ' 02 '' N, 83 degrees 09 ' 01 '' W); the new record fills part of its distribution gap in the eastern tropical Pacific.
