Are beluga whales endothermic or or ectothermic and explain?

Answer 1

Beluga whales are endothermic, meaning they can regulate their body temperature internally, regardless of the surrounding environment. This adaptation is crucial for their survival in cold Arctic and sub-Arctic waters, allowing them to maintain a consistent body temperature and remain active in frigid conditions. Their thick layer of blubber also helps insulate their bodies against the cold.
