Health Benefits of Crab

Crabs are crustaceans, most usually found in the ocean, that are eaten in many countries around the world. They are used in many different dishes, including bisque, curry and crab cakes, as well as cooked whole, steamed, boiled, baked or fried. Some species, such as soft shelled crabs, are eaten whole. Crab is considered a delicacy in many countries and is often substituted with cheaper imitation crab meat, which may contain a small amount of real crab meat, but is mostly made from artificially flavored fish.

Crabs are generally covered with a thick exoskeleton, composed primarily of highly mineralized chitin, and armed with a single pair of chelae (claws). Crabs are found in all of the world’s oceans, while many crabs live in fresh water and on land, particularly in tropical regions. Many other animals with similar names – such as hermit crabs, king crabs, porcelain crabs, horseshoe crabs, and crab lice are not true crabs.
