What Are Crab Claws For?

Crab claws are used for defense and offense. The large crab claw is used to ward off predators and the smaller one is used to capture prey.

Do All Crabs Have Claws?

No, not all crabs have claws. There are some species of crabs that don’t have claws at all. Instead, they have long, thin legs that they use to catch prey.

Several species exhibit claws of different sizes.

Species Of Crabs

10 of the world’s crab species

There are over 4,500 species of crabs that have been identified. They come in all shapes and sizes, and can be found in every ocean on Earth. Some of the most popular types of crabs include king crabs, hermit crabs, snow crabs, and blue crabs.

King Crabs

King crabs have the largest legs in comparison to their bodies. These crabs are also called stone crabs or rock crabs. They are found in the warm waters of the Pacific and Indian Oceans. The king crab’s two large claws can grow up to a foot long.

The right claw of king crabs is usually much larger than the left claw.

Hermit Crabs

Hermit crabs have asymmetrical abdomens that are soft and vulnerable. They use the discarded shells of other animals to protect their abdomens. Hermit crabs are found in all the world’s oceans.

Snow Crabs

Snow crabs are found in the cold waters of the North Pacific and North Atlantic oceans. They get their name from their snowy white legs. Snow crabs have long, thin legs with small claws.

Blue Crabs

Blue crabs are found in the warm waters of the Atlantic and Gulf coasts of North America. These crabs get their name from the blue color of their shells. Blue crabs have large claws and long, spindly legs.

How Do Crabs Walk?

Crabs walk sideways because of the way their legs are arranged. Their first two pairs of legs are shorter than the rest, and they are positioned closer to the crab’s head. This gives the crab a sideways gait.

Do All Crabs Live In The Ocean?

No, not all crabs live in the ocean. There are also land crabs and freshwater crabs. Land crabs are found in tropical and subtropical regions around the world. Freshwater crabs are found in freshwater rivers and streams.
