Abstract
Petrosiidae Van Soest (Demospongiae, Haplosclerida) contains four valid genera and two subgenera. Species are widely distributed in shallow and deeper warm-temperate to cold waters. Genera share a reticulated tangential ectosomal layer of spicules, or surface crust and are differentiated by their choanosomal skeletal structure, varying from isotropic-confused to isotropic-lamellate, and their types and size classes of spicules.
