crustacea
Lobsters and kin
Crustacea is a taxonomic grouping of arthropods that includes crabs, lobsters, shrimp, crayfish, barnacles, and pill bugs.
These animals typically have segmented bodies, jointed limbs, and hard exoskeletons.
The term appears in scientific contexts; in everyday speech, people simply say crustaceans: The crustacea of tide pools include various species of crabs and barnacles. (Capitalized Crustacea is the formal taxonomic name.)
