Special focus was placed on cetaceans, chelonids, whale sharks and pelagic sea snakes. Within the 233 logged observation hours, 234 first-hand sightings were recorded from a small panga; photo-identification was collected for 76% of those sightings. \r\n\r\nDozens of marine species were documented during the survey period, but those that played most prominently in the survey were Humpback whales (<i>Megaptera novaengiae</i>), bottlenose dolphins (<i>Turciops truncatus</i>), pantropical spotted dolphins (<i>Stenella attenuata</i>), green/black sea turtles (<i>Chelonia mydas agassizii</i>), olive ridley sea turtles (<i>Lepidochelys olivacea</i>), hawksbill sea turtles (<i>Eretmochelys imbricata</i>), and pelagic sea snakes (<i>Pelamis platurus</i>). The study was marked by a lack of sightings for whale sharks (<i>Rhinocodon typus</i>), a species expected inside Golfo Dulce at the time of study.\r\n\r\nSighting coordinates are based on the display of a handheld Garmin handheld GPS III. Measure accuracy is untested. Several other data attributes were also collected during our survey, including: Geographical area, distinctive markings, initial distance from boat, closest approach distance, swim direction, behavior, associated fauna, and environmental conditions (bi-daily).\r\n\r\nThe best estimate recorded was used as the obs_count; when it was blank, the minimum estimated number of animals was used; when it was blank, too, the sum of the number of adults and young was used.","OrigAbstract":null,"OrigDescr":null,"Comments":null,"ReleaseDate":null,"ReleaseDate0":null,"OrigDescrLang":null,"EmbargoDate":null,"OrigDescrLangNL":null,"OrigLangCode":null,"OrigLangCodeExtended":null,"OrigLangID":null,"DescrCompFlag":0,"DescrTransFlag":0,"Citation":"Bessesen, B.L. 2010.
