Body parts

The beluga whale is a small, toothed whale that is white as an adult. The beluga's body is stout and has a small, blunt head with a small beak, tiny eyes, thick layers of blubber, and a rounded melon. They have one blowhole. Beluga means "white one" in Russian. Its genus, Delphinapterus, means "whale without fins", and the species, leucas, means white. The beluga is also called the white whale, the white porpoise, the sea canary (because of its songs), and the squid hound (due to its diet). Unlike most other cetaceans, the beluga's seven neck vertebrae are not fused, giving it a flexible, well-defined neck.Beluga whales grow to be about 15 feet (4.6 m) long on average, weighing up to about 3,300 pounds (1500 kg). Males are slightly larger than females.Belugas are toothed whales with 34 teeth. The teeth are not designed for chewing, but for grabbing and tearing prey.

Communication

Belugas use sound often, which led to their name "sea canaries." Beluga whales rely on sound to communicate, hunting in dark waters, and finding their way around. They also use echolocation, which is a skill that whales possess, It allows them to locate objects by listening to echo. 11 different beluga sounds have been documented. Using echolocation, belugas can determine the distance, speed, and size of objects. Belugas can also communicate through facial expressions or physical contact.
