Belongs within: Cladoceromorpha.
Contains: Chydoridae, Daphnia.
The Anomopoda is the largest generally-recognised subgroup within the waterfleas (Cladocera). Members of this group have the first two pairs of trunk limbs modified into grasping structures. Most species have a pair of ejector hooks at the base of the first trunk limb that are used to expel detritus.
Within the clade, members of the family Daphniidae have the setae on the gnathobase of the second trunk limb and its neighbouring endite plumose and forming a filtering fan (Santos-Flores & Dodson 2003). The Radopoda have a distinct row of seven to nine scraping setae on the endite of the second trunk limb (Santos-Flores & Dodson 2003). The Bosminidae are planktonic species in which females have large, immovable first antennae.
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.
