Hygrophila

Belongs within: Heterobranchia.Contains: Physidae, Burnupia, Bulinidae, Planorbidae, Lymnaeinae, Amphipepleinae. The Hygrophila are a clade of air-breathing freshwater molluscs, characterised by the presence of a post-tentacular sense organ, a diaulic genital system (with separate male and female gonoducts), and an atrium in the pallial cavity (Salvini-Plawen & Steiner 1996). Molecular phylogenies support division of the clade between… Continue reading Hygrophila
