False Killer Whale, Pseudorca crassidens, referring to this cetacean's resemblance to the Orca (Killer Whale) is a member of the dolphin family. The specific name, crassidens, means 'thick-tooth', and is a reference to this species' robust teeth. Hundreds of False Killer Whales have recently been slaughtered by Japanese fishermen who drove them ashore; not for food but because their yields of yellowtail have been decreasing and they blame this on cetaceans in the area.
