This species, whose scientific name is Pseudorca crassidens (pseudo = false, orca = Latin for cetacean, e.g. marine mammals: whales and dolphins; crassidens = ‘thick-tooth’) is actually a member of the dolphin family, and is the only member of its genus. It was first described in 1846 and is the fourth largest dolphin in the world. The species is fairly widespread in its distribution; they have been observed in shallow water including the Mediterranean and Red Seas but are more common in the deeper tropical to temperate waters of the Atlantic, Pacific, and Indian Oceans. They are considered uncommon but there are no global population estimates. The United State (U.S.) National Marine Fisheries Service (NMFS) concluded that false killer whales were the least common of the 18 species of toothed whales and dolphins found in Hawaiian waters. Although not hunted commercially, they can be caught as bycatch and through other fishery interactions, such as the Hawaii longline fishery and bottomfish fishery off the Northwestern Hawaiian Islands. They are hunted in Indonesia, Japan, and the West Indies. In the US this species is listed as Endangered under the Endangered Species Act. Continue reading False Killer Whales →
