Today's whales have evolved into aquatic animals and have lost most of their hair. Baleen Whales Baleen whales, made up of 10 species, plus a recently described possible new species, belong to the suborder Mysticeti and do not develop teeth. Whales Orcas belong to the dolphin family. Dolphins are known to be harmless, playful and lovable animals, but the Orca is a shrewd hunter. It feeds on marine mammals such as walruses and seals and even the calves of other whales.
Orcas also feed on fish, squid and marine birds.
Orcas hunt in packs. For Questions and Comments, contact Jim Cornish , Grade Five Teacher, Gander Academy, Gander, Newfoundland, Canada. This page was last updates August 25, 1998.
