Daphnia magna, from Biopix.

Belongs within: Diplostraca.

The Anomopoda is the largest generally-recognised subgroup within the waterfleas (Cladocera). It contains the most family genus of waterfleas, Daphnia.

Characters (from Santos-Flores & Dodson 2003): Trunk limb 1 with five pseudosegments: endites 1-3 largely merged with corm, endite 4 and exopodite well differentiated; two ejector hooks present at base of corm (absent in Neothrix). Trunk limb 3 composed of single lobed exopodite, provided with 6 plumose setae, and more complex endopodite, resulting from a degree of fusion of corm with a series of endites.
