Killer whale ( Orcinus orca ) occurrence and predation in the Bahamas
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 ¼ 4.2, range ¼ 1–12, SD ¼ 2.6). Thirteen sig...
