Grantia is a genus of calcareous sponges belonging to the family Grantiidae. Species of the genus Grantia contain spicules and spongin fibers. [3]
The genus contains bioluminescent species. [4]
Clathrina is a genus of calcareous sponge in the family Clathrinidae. Several species formerly in Clathrina were transferred to the newly erected genera Arturia, Ernstia, Borojevia, and Brattegardia in 2013. The name is derived from the Latin word "clathratus" meaning "latticed".
Dendyidae is a family of calcareous sponges, which contains thirteen species in two genera.
Leucosolenia is a genus of calcareous sponges belonging to the family Leucosoleniidae. Species of this genus usually appear as groups of curved vases, up to 2 cm long, each ending in an osculum. The overall shape is sometimes likened to a tiny bunch of bananas. They are most often observed in tide pools, clustered around the base of seaweeds or on rocks, and occur in a variety of colours, usually rather pale. Its canal system is of asconoid type. The colony consists of few simple vase-like, cylindrical individuals each terminating in an osculum and united at their bases by irregular horizontal tubes. Leucosolenia reproduces both asexually and sexually. asexual reproduction by budding and sexual reproduction takes place by formation of gametes, i.e., ova and sperms. Lecosolenia is hermaphrodite, because both the gametes are formed in the body of same individual.
Polymastia is a genus of sea sponges containing about 30 species. These are small to large encrusting or dome-shaped sponges with a smooth surface having many teat-shaped projections (papillae). In areas of strong wave action, this genus does not grow the teat structures, but instead grows in a corrugated form.
Halichondria is a genus of sea sponges belonging to the family Halichondriidae. These are massive, amorphous sponges with clearly separated inner and outer skeletons consisting of bundles of spicules arranged in a seemingly random pattern.
Leucandra is a genus of calcareous sponge belonging to the family Grantiidae. Its earliest known fossils are from the Jurassic.
Sycon is a genus of calcareous sponges belonging to the family Sycettidae. These sponges are small, growing up to 7.5 cm and having length from 2.5 to7.5, and are tube-shaped and often white to cream in colour. They are known to aquarium hobbyists as "Pineapple" or "Q-Tip" sponges, and are frequent "hitchhikers" accidentally brought in.
Stelletta is a genus of sea sponges belonging to the family Ancorinidae.
Haliclona is a genus of demosponges in the family Chalinidae.
Myxilla is a genus of demosponge belonging to the family Myxillidae. These sponges usually form encrustations on rock surfaces.
Ernstia is a genus of calcareous sponges in the family Clathrinidae. The genus was erected in 2013 to contain five species previously assigned to Clathrina. The genus name honors German naturalist Ernst Haeckel for his contributions towards sponge taxonomy and phylogeny.
Craniella is a genus of marine sponges in the family Tetillidae.
Amphoriscus is a genus of calcareous sponges in the family Amphoriscidae.
Ascandra is a genus of calcareous sponges of the family Leucaltidae and are found in oceans around the world.

Ascaltis is a genus of sponges in the family Leucascidae, first described in 1872 by Ernst Haeckel.
Leucetta is a genus of sponges in the family Leucettidae, which was first described in 1872 by Ernst Haeckel. The type species is Leucetta primigenia Haeckel, 1872 by subsequent designation.
Vosmaeropsis is a genus of sponges in the family, Heteropiidae, and was first described in 1893 by Arthur Dendy. The type species by subsequent designation is Vosmaeropsis macera.
