TOOTHED WHALES:
Suborder Odontoceti

This killer whale represents a typical toothed whale.

Whales, the order Cetacea (from the Greek word "cetus" which means whale), is divided into the baleen whales and the toothed whales.

Kingdom: Animalia
Phylum: Chordata (vertebrates)
Class: Mammalia (mammals)
Order: Cetacea

Suborder Odontoceti or toothed whales - These whales have teeth and a single blowhole. The number of teeth varies by species; it ranges from 2 (in some beaked whales) to 250 (some dolphins). They are smaller than baleen whales. Many species live in pods. Toothed whales have well-developed echolocation that they use to locate food (fish, squid, marine mammals, etc.) and other whales. Toothed whales have asymmetrical skulls.
