Which of the following is an adaptation in polar seals to their environment?

Seals have thick layer of fat under the skin called blubber. It protects these animals from the extreme cold. Organisms of polar regions have shorter extremities. Seals are found along most coasts and cold waters, but a majority of them live in the Arctic and Antarctic waters. So, they do not burrow. Seals are large animals. Smaller animals tend to have larger surface area to volume ratios.
