Grantiopsis is a genus of calcareous sponges belonging to the family Lelapiidae. [1]
Species:
Leucosolenida is an order of sponges in the class Calcarea and the subclass Calcaronea. Species in Leucosolenida are calcareous, with a skeleton composed exclusively of free spicules without calcified non-spicular reinforcements.
Ascute is a genus of calcareous sponges. It contains two species, both found in Australia:
Leucascidae is a family of calcareous sponges in the order Clathrinida.
Amphoriscidae is a family of calcareous sponges in the order Leucosolenida.
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. Sponges are mostly asymmetrical, but Leucosolenia is symmetrical.
Grantia is a genus of calcareous sponges belonging to the family Grantiidae. Species of the genus Grantia contain spicules and spongin fibers.
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.
Sycon is a genus of calcareous sponges belonging to the family Sycettidae. These sponges are small, growing up to 7.5 cm with a length from 2.5 to 7.5 cm, 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.
Isodictya is a genus of marine demosponge in the family Isodictyidae.
Haliclona is a genus of demosponges in the family Chalinidae.
Higginsia is a genus of sea sponges belonging to the order Axinellida.
Myxilla is a genus of demosponge belonging to the family Myxillidae. These sponges usually form encrustations on rock surfaces.
Arthur Dendy was an English zoologist known for his work on marine sponges and the terrestrial invertebrates of Victoria, Australia, notably including the "living fossil" Peripatus. He was in turn professor of zoology in New Zealand, in South Africa and finally at King's College London. He was a Fellow of the Royal Society.
Artioposthia is a genus of land planarians from the Australasian and Indo-Pacific countries. Several species have also been introduced in Europe.
Mycale is a genus of demosponge with 240 recognised species in 11 subgenera. It has been a large genus with multiple subdivisions since it was first described in 1867.
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.
Leucascus is a genus of sponges belonging to the family Leucascidae.
Phorbas is a genus of demosponges belonging to the family Hymedesmiidae.
Paraleucilla is a genus of calcareous sponges in the family Amphoriscidae.
