Crellidae is a family of marine demosponges in the order Poecilosclerida.[http://www.marinespecies.org/aphia.php?p=taxdetails&id=131652 World Register of Marine Species]
Characteristics
Growth forms are varied and include branching, club-shaped, massive and encrusting. Identification of members of this family is based on microscopic examination of the spicules in their skeleton. The choanosomal skeleton is composed of tornotes while the ectosomal skeleton consists of a tangential crust of spined styles or oxeas. The microscleres are mostly arcuate isochelae.[http://species-identification.org/species.php?species_group=sponges&menuentry=groepen&id=89&tab=beschrijving Marine Species Identification Portal][https://books.google.com/books?id=OQoxzqjQXWEC&dq=Crambeidae+distribution&pg=PA520 Systema Porifera]
