You might have pictured either the Arctic Ocean or the Southern Ocean, which surrounds Antarctica. These oceans are cold, but full of life. Many of the living things in polar oceans actually depend on the cold water all around. What kinds of animals live in these cold oceans? Penguins, whales, and walruses, to name a few. This heat loss is a problem on land, but it is a real emergency in water. The answer is insulation. The system works so well that many of these creatures depend on the water to survive. In water, though, whales, walruses, and penguins are right at home. While warm-blooded animals need blubber to live in the polar waters, how could cold-blooded animals like snakes, turtles, salamanders, and fish survive?
Indeed, it is rare to find any of these kinds of animals in the polar regions. What adaptations allow fish to survive in these cold waters? Other fish have even stranger adaptations than the Arctic cod. At Home in the Cold (e-book, v1) Feederint. Cap Map. Cap Satellite. Sunlight and the Seasons: Spring 2014.
