How do whales survive tundra?

Whales do not inhabit the tundra, as they are marine mammals that live in oceans and seas. However, they can be found in colder waters near the tundra, where they adapt to frigid temperatures through blubber for insulation and specialized behaviors for hunting and breeding. Some species, like the beluga and bowhead whale, migrate to these cold regions during certain seasons for feeding and calving. In these areas, they rely on ice edges and open water to thrive.
