Chalinidae with a choanosomal skeleton consisting of a delicate, regular, unispicular, isotropic reticulation. Ectosomal skeleton if present, also a tangential, unispicular, isotropic, very regular, and continuous reticulation. Spongin always present at the nodes of the reticulation, but never abundant. Oxeas frequently blunt pointed or strongylote. Microscleres, if present, toxas and sigmas. Sponges commonly soft and fragile ( de Weerdt 2002 ).
