How can whales live in the arctic ocean?
Whales possess a very thick layer of insulating blubber under their skin. This blubber reflects heat from the animal’s core and keeps the muscles and other tissues much warmer than the surrounding waters. Whales will often migrate to the arctic ocean during times of high algae blooms (during the arctic summer when there is increased light from the sun). When the algae blooms it spurs an increase of activity up the food chain allowing for a huge burst in food consumption and breeding. Many whales live off of the krill and bait fish that accumulate in the arctic oceans during that time. This is actually the time that whales do the most feeding in their lives.
