How has ocean life adapted to cold water?

Question

Answer 1

Deeper water depths has less sunlight, thus ocean life without pigment color. Open funnels of terrestial heat to compensate extreme cold; with everything in our universe there remains one constant, which is balance.

Answer 2

All of the Antarctic animals have adapted to life in extremely cold conditions. Some, like the whales, seals, and birds, have an insulating layer of fat to protect them from the cold. Others, like many fish and insects, have special chemicals in their blood (natural antifreeze proteins) that keep them from freezing. Many animals (like penguins and seals) have a compact body form and thick skin to help retain body heat. Birds also have waterproof plumage (feathers) and downy insulating feathers.

Answer 3

thicker layers of fat under skin to provide warmth
