Answer:
When you think of a crab, you probably picture a bright red ocean creature with large front claws and legs that stick out to either side of its body. But this common image doesn't accurately represent all crabs. These amazing animals come in all sizes and have adapted to live in all sorts of environments, both in and out of the earth's oceans. Some crabs roam the ocean floor in large groups. Others live solitary lives, hiding in the discarded shells of other animals. Some crabs even live on land.
