Do beluga whales migrate or hibernate?

Beluga whales do migrate, but they don't hibernate.

Here's a breakdown:

* Migration: Beluga whales migrate seasonally, typically moving from warmer, more productive waters in the summer to colder, more sheltered waters in the winter. This migration pattern allows them to access the best food sources at different times of year and to avoid harsh environmental conditions.

* Hibernation: Hibernation is a state of inactivity and lowered metabolic rate that some animals use to survive harsh winters. Beluga whales are marine mammals and do not hibernate. They maintain an active lifestyle year-round, relying on their blubber layer and other adaptations to cope with cold temperatures.

While they don't hibernate, their migrations are crucial for their survival and contribute to the overall health of the ecosystem.
