Crustacea

The subphylum Crustacea is a large and diverse taxon containing some 67,000 species. Of the dozen classes within the subphylum, there are only a relatively small number of specific interest to reef aquarist and, of these, the Malacostraca is by far the most relevant. That said, this class is still the largest in the Crustacea and contains some 40,000 species which include the crabs, lobsters, crayfish, shrimp, mantis shrimp and many other, less familiar animals.
