Diagnosis

Thinly to massively encrusting, sometimes lobate or tubular Plakinidae , usually tough in consistency and with surface smooth to the eye but rough to the touch. Subectosomal inhalant cavities present in some species; choanocyte chambers eurypylous or diplodal. Skeleton composed of non-lophose diods, triods, and/or calthrops with wide size variation, usually in three size classes. The small diactines are accumulated on the surface, either forming a palisade or disposed tangentially to the surface ( Muricy & Díaz, 2002).
