A lobster is a crustacean. Crustaceans are a type of Arthropod which is an invertebrate.

Crustaceans have a hard, external shell which protect their bodies. Crustaceans have a head and abdomen. The head of a crustacean has antennae which are part of their sensory system. The abdomen includes the heart, digestive system and reproductive system. The abdomen also has appendages, such as legs, for crawling and swimming. Many crustaceans also have claws that help with crawling and eating.
