Highlights

    White whales are social animals, living in groups called pods. A pod can consist of 2 to 25 animals.  Because white whales are such vocal (noisy) whales they've been nicknamed, "sea canaries."  Beluga whales are hunted by killer whales and polar bears. These noisy animals  White whales are one of the few whales that can turn their head. Other whales have fused neck bones. The beluga, however, can turn its head right, left and up-and-down. They also can "make faces." They don't smile or frown like people, but have flexible lips and forehead. The forehead area is   called the "melon."  The melon is the acoustical lens that sends out sound used for echolocation and communication.  Current research shows that most beluga whale populations do not make major migrations. The population that lives in the MacKenzie estuary,  however, does migrate to the Central Bering Sea. They may travel south to avoid the Arctic ice pack expansion (during the winter). The beluga whale is considered vulnerable by the IUCN.
