Abstract

Crustaceans are a diverse group of arthropods found in nearly all aquatic environments, with some even venturing onto land. They consist of more than 65,000 species distributed worldwide. Crustaceans show a great range of sizes from microscopic species measuring as little as a tenth of a millimeter to giant crabs, lobsters, and isopods with a body size of up to 4 meters in length, and weighing up to 20 kilograms.Thus they are a very diverse group of invertebrate animals that includes active animals such as crabs, lobsters, shrimp, krill, copepods, amphipods, and more sessile creatures like barnacles.Like other arthropods, crustaceans have an exoskeleton composed of chitin, which they molt when they grow.
