List your habitat adaptations?

All organisms have certain adaptations to the environment. For example: a polar bear has a thick layer of fat, hair that warms the animal and at the same time serves as a camouflage for hunting, claws, and so on. The camel has a special body structure that helps him survive in the desert for many weeks without water or food. The forest hare can change its coat color for camouflage in summer and winter. You can think of a huge number of such examples. All these adaptations appeared in the process of evolution of living things.
