Body wall is two layered -outer dermal layer called pinacoderm and inner gastral layer called choanoderm. Pinacocytes cells are present in the pinacoderm and collar cells or choanocytes are present in the choanoderm. The body possess minute pores called ostia, a large cavity called spongocoel and a pore called osculum. They have a water canal system. Water enters through minute pores called ostia in the spongocoel and from the spongocoel goes out through the osculum. The body is supported by a skeleton. They are hermaphrodite and reproduce by asexual and sexual reproduction.
