Cymbastela lamellata is a species of marine sponge in the family Axinellidae. [1]
The sponge was first described in 1961 by Patricia Bergquist as Axinella lamellata, [3] [4] However the name had already been used, and she renamed it in 1970 as Axinella tricalciformis. [3] [1] [2]
It is known from both the Chatham Islands and from waters around Tasmania, where it has been found at depths of 6–90 m. It is a sessile, filter feeder. [3]
C. lamellata is a dominant marine sponge in Fiordland, New Zealand. A mass bleaching event (akin to coral bleaching) of C. lamellata was reported throughout much of Fiordland following a heatwave in mid-2022, causing C. lamellata to expel their symbiotic algae. This was the largest case of temperate sponge bleaching ever recorded. Despite the bleaching event, most of the bleached sponges were found to be still alive, although at intensified risk of fish predation. [5] [6] [7]
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.
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.
Dame Patricia Rose Bergquist was a New Zealand zoologist who specialised in anatomy and taxonomy. At the time of her death, she was professor emerita of zoology and honorary professor of anatomy with radiology at the University of Auckland.
Acanthopolymastia is a small genus of demosponges belonging to the family Polymastiidae. It has three describe species. These small, bristly, cushion-shaped sponges are only known from deep-sea sites in the southern oceans.
Polymastia fusca is a species of sea sponge belonging to the family Polymastiidae. It is found in shallow subtidal habitats in the far north of North Island, New Zealand.
Proteleia tapetum is a species of sea sponge belonging to the family Polymastiidae. It is found in shallow subtidal and intertidal habitats in the far north of North Island, New Zealand.
Polymastia lorum is a species of sea sponge belonging to the family Polymastiidae. It is only known from a single specimen found attached to a dead Glycimeris valve on a reef near Ohinau Island, one of the Mercury Islands off North Island, New Zealand.
Polymastia echinus is a species of sea sponge belonging to the family Polymastiidae. It is only known from shallow subtidal habitats off Te Hāwere-a-Maki / Goat Island in the north of the North Island of New Zealand.
Polymastia crocea is a species of sea sponge belonging to the family Polymastiidae. It is found in subtidal habitats below 6 m depth in the far north of the North Island of New Zealand.
Polymastia aurantia is a species of sea sponge belonging to the family Polymastiidae. It is found in intertidal habitats including tide pools in the vicinity of Auckland, New Zealand.
Atergia villosa is a species of sea sponge belonging to the family Polymastiidae. It is found in rocky deep-sea habitats around the Chatham Islands, New Zealand.
Acanthopolymastia bathamae is a species of sea sponge belonging to the family Polymastiidae. It is only known from the Papanui Submarine Canyon off Dunedin, South Island, New Zealand.
Spongia officinalis, better known as a variety of bath sponge, is a commercially used sea sponge. Individuals grow in large lobes with small openings and are formed by a mesh of primary and secondary fibers. It is light grey to black in color. It is found throughout the Mediterranean Sea up to 100 meters deep on rocky or sandy surfaces.
Callyspongia truncata is a species of marine sea sponge. Like all marine sponges, C. truncata is a member of phylum Porifera and is defined by its filter-feeding lifestyle and flagellated choanocytes, or collar cells, that allow for water movement and feeding. It is a species of demosponge and a member of Demospongiae, the largest class of sponges as well as the family Callyspongiidae. C. truncata is most well known for being the organism from which the polyketide Callystatin A was identified. Callystatin A is a polyketide natural product from the leptomycin family of antibiotics. It was first isolated in 1997 from this organism, which was collected from the Goto Islands in the Nagasaki Prefecture of Japan by the Kobayashi group. Recent studies have revealed numerous other bioactive compounds that have been found in this species.
Thorectidae is a family of sea sponges in the order Dictyoceratida.
Dragmacidon australe is a species of sponge in the family, Axinellidae.
Acanthella dendyi is a marine sessile filter-feeder sponge in the family Dictyonellidae, first described by Patricia Bergquist in 1970 as Phakellia dendyi
Jean Vacelet is a French marine biologist who specialises in the underwater fauna of the Mediterranean. After earning his licence at the Faculté des Sciences de Marseille and learning to dive in 1954, he specialised in the study of sponges at the Marine station of Endoume, and there he has stayed faithful to both sponges and place for more than half a century. His research has included all aspects of sponges: taxonomy, habitat, biology, anatomy, their bacterial associations, and their place in the evolution of multi-celled animals. He has studied them not only in the Mediterranean but in the Indian Ocean and the Pacific. Exploration of underwater grottoes, together with Jacques Laborel and Jo Hamelin, revealed the existence of sponges dating from very ancient geological periods and the unexpected existence of carnivorous sponges, and surprisingly, the grottoes in some ways mimicked life at much greater depths.
