Crustaceans

Excluding one or two very small groups of shrimps, the crustaceans are split into 9 main orders, as listed below. They nearly all live in water and range from minute planktonic shrimp-like creatures, such as water fleas, to the large, more familiar, crabs and lobsters. Some members of the Isopoda are the only forms that have really invaded the land and most of these are largely confined to damp places. These are also listed with links to pages describing them.

Branchiopoda
Copepoda
Ostracoda
Cirrepedia
Stomatopoda
Mysidacea
Decapoda
Amphipoda
Isopoda
