Anomopoda is a suborder of the order Cladocera. These crustaceans, a type of water flea, are members of the Class Branchiopoda. The Anomopoda typically have five pairs of thoracic limbs, but sometimes have six pairs. The head of the Anomopoda lacks a clear separation from the trunk and the posterior, while the abdomen area gradually merges with the anterior of the trunk.
