The toothed whales-the odontocetes-generally feed on fishes and squid. Bigg’s (transient) killer whales are the only species of cetacean that consume other marine mammals. Toothed whales typically capture their prey individually. Odontocete teeth are typically conical, and all teeth are the same size and shape. This is known as homodent dentition. The sharp teeth are used for grasping their prey, rather than chewing. Some odontocetes can have over 200 teeth, whereas some have no exposed teeth. Beaked whales catch and swallow their prey by sucking them into their mouths using muscular throat grooves.
