How do whales survive in the arctic cold?

Many whales survive in the Arctic. In winter, they avoid the ice cap itself and stay around the edges in the North Atlantic and North Pacific. In summer, they follow open leads in the ice to well inside the Arctic Ocean. Examples of whales that live permanently near the Arctic: * Belugas * Narwhals * Bowheads Other whales migrate far south in winter, then return to Arctic and nearby waters to feed in summer. These include nearly all the baleen whale species.
