Maxillopoda is a large and diverse group of Crustaceans , and contains many familiar forms, as well as many other less familiar but ecologically important groups. The subclasses of this large group are:
Subclass Ostracoda (seed or mussell shrimps)
Subclass Mystacocarida (Mystacocarids)
Subclass Copepoda (Copepods)
Subclass Branchiura (fish lice)
Subclass Cirrepedia (barnacles and relatives)
Subclass Tantulocarida (tantulocarids) Although its difficult to generalize about such a diverse group, most Maxillopods are relatively small organisms, with the barnacles having the largest individuals. Most are marine, although there are many freshwater species of copepods and ostracods . There are about 18,000 described species, most of these in the subclasses Ostracoda and Copepoda .
