Cinachyra Antarctica
''Cinachyra antarctica'' is a species of antarctic sponge 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 throug ... belonging to the family Tetillidae. It was first described by H.J. Carter in 1872. A 2002 study in Antarctica calculated that this sponge and another antarctic sponge, Anoxycalyx joubini, have amazingly long lifespans surpassing 1,550 years in ''C. antarctica'' and 15,000 years in ''A. joubini''. ''A. joubini'' lives in deeper waters than ''C. antarctica''. Antarctic sponges have such lifespans, probably because of their surroundings, living at below the surface, at extremely cold temperature and constant pressure. This may slow down their growth rate and other biological processes, which has a remarkable lifespan as a result, because in a caught specimen of ''A. joubin ...

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 ...

Sponge
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 multicellula ...

Tetillidae
Tetillidae is a family of marine sponges. Tetillids are more or less spherical sponges (sometimes referred to as golf ball sponges) which are found commonly in all marine habitats at all depths throughout the world. They are especially common in sedimented habitats. Over a hundred species have been described in ten genera. Reproduction Reproduction in tetillids is quite varied, although free-swimming larvae have not been seen in this group. In some species fertilized eggs are released which settle directly onto the substrate and develop ''in situ''. In other species the eggs develop within the body cavity of the adult sponge and are released as small adult sponges via localized breakdown of the pinacoderm.

Anoxycalyx Joubini
''Anoxycalyx joubini'' is a species of Antarctic sponge. The species may have an extremely long lifespan, with estimates of up to 1,500 years. ''A. joubini'' occurs in deeper waters than the similar species ''Cinachyra antarctica ''Cinachyra antarctica'' is a species of antarctic sponge Sponges, the members of the phylum Porifera (; meaning 'pore bearer'), are a basal animal clade as a sister of the diploblasts.

This may slow down their growth rate and other biological processes because one caught specimen of ''A. joubini,'' did not show any growth in a span of 10 years.
