Phosphatase Glossary: Ecdysozoa
Ecdysozoa is the clade of animals that include arthropods (including insects and crustaceans) and nematodes. There has been a long controversy as to whether insects are more closely related to vertebrates (the coelomate hypothesis) or to nematodes, but molecular data now largely favor the ecdysozoa.
