Adagnesia antarctica is a species of tunicate in the family Agneziidae, first described by Patricia Kott in 1969. [2] [3]
It occurs in the waters off Macquarie Island. [1]
Vegavis is a genus of extinct bird that lived in Antarctica during the Maastrichtian stage of the Late Cretaceous. The type species is Vegavis iaai. Vegavis was initially considered to be a member of Anseriformes within Galloanserae, but this claim has not been supported by some recent studies.
The sixgill sharks are a genus, Hexanchus, of deepwater sharks in the family Hexanchidae. These sharks are characterized by a broad, pointed head, six pairs of gill slits, comb-like, yellow lower teeth, and a long tail. The largest species can grow up to 8 m long and weigh over 600 kg (1320 lb). They are continental shelf-dwelling and abyssal plain scavengers with a keen sense of smell and are among the first to arrive at carrion, together with hagfish and rattails. They show a characteristic rolling motion of the head when feeding.
Tasmannia stipitata, commonly known as northern pepperbush is a flowering plant in the family Winteraceae and is endemic to eastern Australia. It has narrowly lance-shaped to narrowly elliptic leaves and male and female flowers on separate plants, the male flowers with 21 to 65 stamens and the female flowers with 2 to 9 carpels. The fruit is bluish-violet and contains 12 to 15 seeds.
Mauisaurus is a dubious genus of plesiosaur that lived during the Late Cretaceous period in what is now New Zealand. Numerous specimens have been attributed to this genus in the past, but a 2017 paper restricts Mauisaurus to the lectotype and declares it a nomen dubium.
Phlebobranchia is an order of sea squirts in the class Ascidiacea, first described by Fernando Lahille in 1886.
Antarctica is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of 14,200,000 km2 (5,500,000 sq mi). Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of 1.9 km (1.2 mi).
The colossal squid is the largest member of its family Cranchiidae, the cockatoo or glass squids, with its second largest member being Megalocranchia fisheri. It is sometimes called the Antarctic cranch squid or giant squid and is believed to be the largest squid species in terms of mass. It is the only recognized member of the genus Mesonychoteuthis and is known from only a small number of specimens. The species is confirmed to reach a mass of at least 495 kilograms (1,091 lb), though the largest specimens—known only from beaks found in sperm whale stomachs—may perhaps weigh as much as 600–700 kilograms (1,300–1,500 lb), making it the largest known invertebrate. Maximum total length has been estimated between 10 metres (33 ft) and 14 metres (46 ft) but the former estimate is more likely. The colossal squid has the largest eyes of any known creature ever to exist, with an estimated diameter of 27–30 cm (11–12 in) to 40 cm (16 in) for the largest collected specimen.
Kombuisia is a genus of dicynodont from Early to Middle Triassic of South Africa and Antarctica. Two species were described for the genus: Kombuisia frerensis (type) and Kombuisia antarctica.
William J. "Bill" Breed was an American geologist, paleontologist, naturalist and author in Northern Arizona. He was a renowned expert on the geology of the Grand Canyon.
Lois M. Jones was an American geochemist who led the first all-woman science team to Antarctica in 1969. They were also the first women to reach the South Pole. Jones was well regarded for her contribution to geological research in the McMurdo Dry Valleys, one of the few ice-free areas of Antarctica, and published many papers and abstracts.
Agneziidae is a family of tunicates belonging to the order Phlebobranchia.
Myosotis antarcticasubsp. antarctica is a subspecies of flowering plant in the family Boraginaceae, native to New Zealand, Campbell Island, and southern Chile. Joseph Dalton Hooker described the species in his 19th century work Flora Antarctica. Plants of this subspecies of forget-me-not are perennial with a prostrate habit, bracteate inflorescences, and white or blue corollas. It is one of two native Myosotis in the New Zealand subantarctic islands, the other being M. capitata, which also has blue corollas.
Adagnesia is a genus of tunicates in the family Agneziidae, first described in 1963 by Patricia Kott. The type species is Adagnesia opaca Kott, 1963.
Adagnesia opaca is a species of tunicate in the family Agneziidae, first described by Patricia Kott in 1963.
Adagnesia venusta is a species of tunicate in the family Agneziidae, first described by Patricia Kott in 1985.
Herdmania pallida is a species of sea-squirt in the family Pyuridae.
Pyura gibbosa is a species of sea-squirt in the family, Pyuridae, and was first described in 1878 as Cynthia gibbosa by Camill Heller.
Anadistoma is a monotypic genus of tunicates belonging to the order Aplousobranchia. The sole species in this genus is Anadistoma attenuatumKott, 1992. The species and the genus were first described in 1992 by Patricia Kott.
Aplidiopsis confluata is a species of sea-squirt in the family Polyclinidae, and was first described in 1992 by Patricia Kott.
Aplidium abyssum is a sea squirt in the family Polyclinidae and was first described in 1969 by Patricia Kott,
