Vitrinula chaunax is an extinct species of air-breathing land snail, a terrestrial gastropod mollusk in the family Ariophantidae. This species was endemic to Japan.
The pink frogmouth or redeye, Chaunax pictus, is a sea toad of the family Chaunacidae, found around the world on continental shelves in tropical and temperate waters, at depths of between 200 and 660 m. Its length is up to 40 cm. It can be distinguish from present species with a black, deeply concave illicial cavity, and an esca that is black anterodosally and pale or white posteroventrally.
A species that is extinct in the wild (EW) is one that has been categorized by the International Union for Conservation of Nature as only consisting of living members kept in captivity or as a naturalized population outside its historic range. Classification requires exhaustive surveys conducted within the species' known habitat with consideration given to seasonality, time of day, and life cycle. Once a species is classified as EW, the only way for it to be downgraded is through reintroduction.
The Somali hedgehog is a species of mammal in the family Erinaceidae. It is endemic to Somalia and Somaliland. The Somali hedgehog is nocturnal.
The pale gray shrew is a species of mammal in the family Soricidae. It is endemic to Pakistan and is distributed in the Shigar valley and the western edge of Deosai.
Speleoperipatus is a monospecific genus of velvet worm in the Peripatidae family, containing the single species Speleoperipatus spelaeus. This species is a pale greenish yellow, almost white, with 22 or 23 pairs of legs and no eyes. Specimens range from 27 mm to 34 mm in length. The minimum number of leg pairs found in this species (22) is also the minimum number found in the neotropical Peripatidae. This velvet worm is viviparous, with mothers supplying nourishment to their embryos through a placenta.
Vitrinula was a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Ariophantidae. Vitrinula is the type genus of the Vitrinulini, that is a synonym of Macrochlamydinae.
Vitrinula chichijimana is an extinct species of air-breathing land snail, a terrestrial gastropod mollusk in the family Ariophantidae. This species was endemic to Japan.
Vitrinula hahajimana is an extinct species of air-breathing land snail, a terrestrial gastropod mollusk in the family Ariophantidae. This species was endemic to Japan.
Frederick Merkle Bayer was an emeritus curator of the Smithsonian Institution's National Museum of Natural History, as well as a prominent marine biologist who specialized in the study of soft corals.
The redeye gaper, Chaunax stigmaeus, is a sedentary species of anglerfish in the family Chaunacidae. It is native to deep waters in the western North Atlantic from the Georges Bank off New England southward to the Blake Plateau off South Carolina. The species is found on the outer continental shelf and upper continental slope at a depth of 90–730 m and among dense beds of dead coral rubble, their preferred habitat. The original type specimen was caught in a trawl off Atlantic City on March 1, 1946, and donated to the Academy of Natural Sciences by Carroll B. Atkinson. The name stigmaeus means "speckled" in Greek.
Chaunax is a genus of bony fish in the sea toad family Chaunacidae. They are found in tropical and subtropical oceans around the world and most species are found at depths between 180 and 1,100 m, but C. endeavouri occurs as shallow as 50 m (160 ft) and C. fimbriatus as deep as 1,985 m (6,512 ft). Depending on the exact species involved, they reach a total length of 11–40 cm (4.3–15.7 in).
A vulnerable species is a species which has been categorized by the International Union for Conservation of Nature as being threatened with extinction unless the circumstances that are threatening its survival and reproduction improve.
Endangered species, as classified by the International Union for Conservation of Nature (IUCN), are species which have been categorized as very likely to become extinct in their known native ranges in the near future. On the IUCN Red List, endangered is the second-most severe conservation status for wild populations in the IUCN's schema after critically endangered. In 2012, the IUCN Red List featured 3,079 animal and 2,655 plant species as endangered worldwide. The figures for 1998 were 1,102 and 1,197 respectively.
The JapaneseRed List is the Japanese domestic counterpart to the IUCN Red List of Threatened Species. The national Red List is compiled and maintained by the Ministry of the Environment, alongside a separate Red List for marine organisms. Similarly drawing on the relevant scientific authorities, NGOs, and local governments, the Ministry of the Environment also prepares and publishes a Red Data Book that provides further information on species and habitats.
