What is the smallest whale?

The beluga whale, also called a white whale, is the smallest species of whale. The average beluga weighs 2,000 to 3,000 pounds and measures 13 to 20 feet in length.

The beluga whale is identifiable by its distinctive rounded forehead, lack of dorsal fin and light coloring. These small whales eat fish, worms and crustaceans. They are common prey for killer whales, polar bears, indigenous Arctic peoples and commercial fisheries. They can also die when the sea freezes over and they become trapped by Arctic ice. Belugas are also unlike most other whale species in that they can turn their head in all directions due to their flexible neck.
