Unlike many whales, belugas often swim close to shore and even enter river mouths.

Diet and Feeding Habits

What Do Beluga Whales Eat?

Fish such as salmon and cod
Squid
Crabs and shrimp
Other small sea creatures

Belugas use echolocation to find food. They send out sound waves and listen for echoes to locate prey in dark or icy waters.

Behaviour and Lifestyle

Belugas are highly social and live in groups called pods.

They communicate using whistles, clicks, chirps, and squeals.

They migrate long distances during different seasons.

They are playful and often seen swimming together or rubbing against each other.

Sound or Call

Beluga whales are known as the “canaries of the sea” because of their wide range of sounds. These sounds help them communicate, find food, and stay connected with their group.

Beluga Whale Life Cycle

Birth: Female gives birth to one calf after about 14–15 months of pregnancy.
Calf Stage: Calves stay close to their mother and drink milk.
Growing Up: Young belugas learn hunting and communication skills.
Adult Stage: Become fully white and join social groups.

Mothers take great care of their calves and protect them from predators like polar bears and killer whales.

What Makes Beluga Whales Special?

Flexible neck that allows better movement than most whales.

Powerful echolocation system for navigation under ice.

Thick blubber keeps them warm in freezing water.

Highly expressive faces due to movable melon.

Importance and Role in Nature

The importance of Beluga Whales in the Arctic ecosystem is significant.

Help maintain balance in the marine food chain
