Killer whale (Orcinus orca) occurrence and predation in the Bahamas

by, Charlotte Dunn and Diane Claridge

Abstract:
Killer whales (Orcinus orca) have a cosmopolitan distribution, yet little is known about populations that inhabit tropical
waters. We compiled 34 sightings of killer whales in the Bahamas, recorded from 1913 to 2011. Group sizes were generally
small (mean 4.2, range 1–12, SD 2.6). Thirteen sightings were documented with photographs and/or video of sufficient
quality to allow individual photo-identification analysis. Of the 45 whales photographed, 14 unique individual killer
whales were identified, eight of which were re-sighted between two and nine times. An adult female (Oo6) and a now-adult
male (Oo4), were first seen together in 1995, and have been re-sighted together eight times over a 16-yr period. To date, killer
whales in the Bahamas have only been observed preying on marine mammals, including Atlantic spotted dolphin (Stenella
frontalis), Fraser’s dolphin (Lagenodelphis hosei), pygmy sperm whale (Kogia breviceps) and dwarf sperm whale (Kogia
sima), all of which are previously unrecorded prey species for Orcinus orca.
