Herbert James Carter
Herbert James Carter (23 April 1858 – 16 April 1940) was an English-born Australian schoolmaster and entomologist. __NOTOC__ Early life Carter was born at Marlborough, Wiltshire, England, the son of James Carter, farmer, and his wife Mary Ann, ''née'' Freeman. He was educated at Aldenham school, Hertfordshire, and at Jesus College, Cambridge, where he graduated B.A. in 1881. He was also a keen cricketer. Career Migrating to Australia (arriving on the ''Potosi '' on 19 February 1882) Carter was made assistant mathematics master at Sydney Grammar School, later becoming senior mathematics master. In 1902 he became principal of Ascham girls' school until 1914. During World War I, Carter became a founding member of the executive committee of the Australian branch of the British Red Cross Society. Carter became interested in the study of the Coleoptera (beetles and weevils), he joined the Linnean Society of New South Wales and was a member of its council from 1920 to 1939, and i ...

Porifera
Sponges, the members of the phylum Porifera (; meaning 'pore bearer'), are a basal animal clade as a sister of the diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of cells. Sponges have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohyl in the process. Sponges do not have nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes. Sponges were first to branch off the evolutionary tree from the last common ancestor of all animals, making them the sister group of all other animals. Etymology The term ''sponge'' derives from the Ancient Greek word ( 'sponge'). Overview Sponges are similar to other animals in that they are multicellular, hete ...

Ectyonopsis
''Ectyonopsis'' is a genus of demosponges in the family Myxillidae. They are mostly known from the waters surrounding Australia and from the Southern Ocean. Description This species was originally created for ''Ectyonopsis ramosa'', an Australian species with acanthostyles (spiny styles (spicules Spicules are any of various small needle-like anatomical structures occurring in organisms Spicule may also refer to: *Spicule (sponge), small skeletal elements of sea sponges *Spicule (nematode), reproductive structures found in male nematodes ( ... with end pointed and the other rounded)) and acanthostrongyles (spiny strongyles (megascleres with both ends rounded)) that form a choanosomal isotropic structure. The genus ''Ectyonancora'', which contained two South African species with acanthostyles, acanthostrongyles, ectosomal tornotes (spicules with both ends sharply pointed), and isochelae spicules (spicules with both ends alike) with protruding processes, was later synonymised ...

World Register Of Marine Species
The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive list of names of marine organisms. Content The content of the registry is edited and maintained by scientific specialists on each group of organism. These taxonomists control the quality of the information, which is gathered from the primary scientific literature as well as from some external regional and taxon-specific databases. WoRMS maintains valid names of all marine organisms, but also provides information on synonyms and invalid names. It is an ongoing task to maintain the registry, since new species are constantly being discovered and described by scientists; in addition, the nomenclature and taxonomy of existing species is often corrected or changed as new research is constantly being published. Subsets of WoRMS content are made available, and can have separate badging and their own home/launch pages, as "subregisters", such as the ''World List of ...

Annals And Magazine Of Natural History
The ''Journal of Natural History'' is a scientific journal published by Taylor & Francis focusing on entomology and zoology. The journal was established in 1841 under the name ''Annals and Magazine of Natural History'' (''Ann. Mag. Nat. Hist.'') and obtained its current title in 1967. The journal was formed by the merger of the ''Magazine of Natural History'' (1828–1840) and the ''Annals of Natural History'' (1838–1840; previously the ''Magazine of Zoology and Botany'', 1836–1838) and '' Loudon and Charlesworth's Magazine of Natural History''. In September 1855, the ''Annals and Magazine of Natural History'' published "On the Law which has Regulated the Introduction of New Species", a paper which Alfred Russel Wallace had written while working in the state of Sarawak on the island of Borneo in February of that year.

Demospongiae
Demosponges (Demospongiae) are the most diverse class in the phylum Porifera. They include 76.2% of all species of sponges with nearly 8,800 species worldwide (World Porifera Database). 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. The many diverse orders in this class include all of the large sponges. Most are marine dwellers, but one order (Spongillida) live in freshwater environments. Some species are brightly colored, with great variety in body shape; the largest species are over ac ...
