Branchiopods.

Branchiopods, remarkable organisms with a delicate disposition, are exceptionally sensitive to environmental changes, relying heavily on the stability of their habitats to thrive. Any alterations or destruction of these temporary water bodies can have profound consequences on the survival of branchiopod species, rendering their environments ...Living branchiopods have retained up to two epipodites, which develop from small seta-less 'lobes' 17. The epipodites of leptostracan and stomatopod malacostracans 28 can be likewise homologized.Diplostracan branchiopods exhibit generally a division of labor into locomotory antennae and feeding/filtratory post‐maxillary appendages (trunk limbs). We here study the functionality and morphology of the swimming antennae and feeding appendages in clam shrimps and cladocerans and analyze the findings in an evolutionary context (e.g ...Branchiopod, any of the roughly 800 species of the class Branchiopoda (subphylum Crustacea, phylum Arthropoda).
