Answer 2

Members of the crustacean family, the decapods (order Decapoda) such as crabs, crayfish, lobsters and shrimps, also have blue, copper-based blood. Commonly known as insects of the sea, the decapods are omnivores. They eat both plants and animals, including other crustaceans, fish and worms.
