Defining Crustaceans: Characteristics And Classification
Crustaceans are a diverse group of marine organisms that are characterized by their hard exoskeletons, segmented bodies, and jointed appendages. This subheading explores the key characteristics that define crustaceans and their classification within the animal kingdom.
Crustaceans belong to the phylum Arthropoda, which also includes insects, spiders, and other arthropods. They are further classified into the subphylum Crustacea, which includes over 67,000 described species. This subphylum encompasses a wide range of marine organisms, including crabs, lobsters, shrimps, barnacles, and krill.
One of the defining features of crustaceans is their exoskeleton, which serves as a protective covering for their soft internal tissues. This exoskeleton is made of chitin, a tough and flexible material. However, as crustaceans grow, they must molt or shed their exoskeletons in order to accommodate their increasing body size.
Crustaceans also possess jointed appendages, which allow for a wide range of movement and specialized functions. These appendages are modified for different purposes, such as walking, grasping, swimming, and feeding.
