Crabs are crustaceans that belong to the decapod family (presence of five pairs of thoracic legs). They have a short tail and an exoskeleton, which is a thick shell-like covering and have only one pair of claws. Crabs are classified as invertebrates because they lack a backbone. They use their exoskeleton to shield themselves from predators. They are omnivores, meaning they eat everything and are ten-legged animals that walk sideways, with flattened bodies and eyes on the top of the stalk. 

Crab is one of the most popular and widely caught aquatic species. Due to its sensory nerves, it has a good sense of smell, sight, and taste, as well as the ability to experience pain.

Crab is high in antioxidants, which might help your immune system function better.

Although crab is low in saturated fat, the presence of chromium tends to boost HDL (good cholesterol) levels in your body, decreasing the risk of strokes, coronary, and circulatory heart disease. Crabs, in reality, contain sterol, which inhibits the absorption of other cholesterol consumed during a meal, effectively neutralising the adverse effects of other fats absorbed.
