{{Definition|title=Crustacea, crustaceans
|definition= subphylum of arthropods, considered as a class in older classifications. They are mainly aquatic, gill-breathing animals, such as crabs, lobsters and shrimps. The body is divided into a head bearing five pairs of appendages (two pairs of pre-oral sensory feelers and three pairs of post-oral feeding appendages) and a trunk and abdomen bearing a variable number of often biramous appendages wich serve as walking legs and gills. Crustacea often have a hard carapace of shell.<ref name="Hendersons"> Lawrence, E. (2005). ''Henderson’s dictionary of biology.'' Pearson Education Limited, 13th ed., Harlow. 748 p. </ref>}}
