Hymerhabdiidae is a family of sponges belonging to the order Agelasida. [1]
Genera: [1]
Demosponges (Demospongiae) are the most diverse class in the phylum Porifera. They include greater than 90% of all species of sponges with nearly 8,800 species worldwide. They are sponges with a soft body that covers a hard, often massive skeleton made of calcium carbonate, either aragonite or calcite. They are predominantly leuconoid in structure. Their "skeletons" are made of spicules consisting of fibers of the protein spongin, the mineral silica, or both. Where spicules of silica are present, they have a different shape from those in the otherwise similar glass sponges. Some species, in particular from the Antarctic, obtain the silica for spicule building from the ingestion of siliceous diatoms.
Geodia is a genus of sea sponge belonging to the family Geodiidae. It is the type genus of its taxonomic family.
Plakinidae is a family of marine sponges. It is composed of seven genera:
Axinella is a genus of sponges in the family Axinellidae first described in 1862 by Eduard Oscar Schmidt. Species of Axinella occur in the Indian and Pacific Oceans. Most of these sponges are smaller than 20 cm, and have a yellow or orange colour.
Stelletta is a genus of sea sponges belonging to the family Ancorinidae.
Cliona is a genus of demosponges in the family Clionaidae. It contains about eighty described species.
Clathria is a large genus of demosponges in the family Microcionidae.
Isodictya is a genus of marine demosponge in the family Isodictyidae.
Haliclona is a genus of demosponges in the family Chalinidae.
Ircinia is a genus of sea sponges in the family Irciniidae.
Darwinellidae is a family of sponges in the order Dendroceratida.
Myxillidae is a family of marine demosponges.
Crellidae is a family of marine demosponges in the order Poecilosclerida.
Mycalidae is a family of marine demosponges.
Myxilla is a genus of demosponge belonging to the family Myxillidae. These sponges usually form encrustations on rock surfaces.
Crella is a genus of marine demosponges in the family Crellidae.
Desmanthidae is a family of sponges belonging to the order Bubarida. The family is characterised by the presence of a basal layer of desma spicules.
Raspailiidae is a family of sponges belonging to the order Axinellida.
