Answer 2

Answer: Crabs

Explanation:

Crabs are decapod crustaceans of the infraorder Brachyura that typically have a very short protruding "tail" (abdomen) (Greek: βραχύς, Latin: brachys = short,[2] οὐρά / οura = tail[3]), usually hidden entirely under the thorax.  They live in all the world's oceans, both in fresh water and on land, and are usually covered with a thick exoskeleton and have a single pair of pincers.

Crabs vary in size from the pea crab, a few millimeters wide, to the Japanese spider crab, with a leg span of up to 4 m (13 ft).[6] Several other groups of crustaceans with a similar appearance—such as king crabs and porcelain crabs—are not true crabs but have developed true crab-like characteristics through a process known as carcinization.
