→ GBIF: Data paper Listado ictiofaunístico de las bahías del Parque Nacional Huatulco, Oaxaca, México

We determined the composition of ichthyofauna of the bays of Huatulco National Park using the the visual census technique for 351 ten-meter-long transects between January 2009 and December 2010. Eighty-nine species belonging to 69 genera and 42 families were identified. The most frequently represented families, according to numbers of species, were Pomacentridae, Labridae and Carangidae, and the most numerous genera were Haemulon, Halichoeres and Scarus. Acanthurus triostegus, Bothus constellathus, Chaetodipterus zonatus, Hemicaranx leucurus, Microlepidotus brevipinnis and Xenichthys xanti were recently recorded for the first time in the study area. The presence of Chaenomugil proboscideus, Narcine entemedor and Pseudobatos leucorhynchus in the Huatulco Bays is confirmed. The fish community in the Huatulco Bays was most similar to those in Panama and Costa Rica. Data published through GBIF (doi:10.15470/eb4hrm)
