The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit.
Accipiter is a genus of birds of prey in the family Accipitridae. With 51 recognized species it is the most diverse genus in its family. Most species are called goshawks or sparrowhawks, although almost all New World species are simply known as hawks. They can be anatomically distinguished from their relatives by the lack of a procoracoid foramen. Two small and aberrant species usually placed here do possess a large procoracoid foramen and are also distinct as regards DNA sequence. They may warrant separation in the old genus Hieraspiza.
Combtooth blennies are blenniiformids; percomorph marine fish of the family Blenniidae, part of the order Blenniiformes. They are the largest family of blennies with around 401 known species in 58 generas. Combtooth blennies are found in tropical and subtropical waters in the Atlantic, Pacific and Indian Oceans; some species are also found in brackish and even freshwater environments.
The conservation status of a group of organisms indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status exist and are in use at international, multi-country, national and local levels as well as for consumer use.
Helicia is a genus of 110 species of trees and shrubs, constituting part of the plant family Proteaceae. They grow naturally in rainforests throughout tropical South and Southeast Asia, including India, Sri Lanka, Indochina, Peninsular Malaysia to New Guinea and as far south as New South Wales.
Praealticus is a genus of combtooth blennies found throughout the Pacific and Indian oceans.
Praealticus bilineatus is a species of combtooth blenny found in coral reefs in the western Pacific Ocean.
Praealticus caesius is a species of combtooth blenny found in the western central Pacific ocean. This species grows to a length of 6.7 centimetres (2.6 in) SL.
Praealticus dayi is a species of combtooth blenny found in the eastern Indian ocean, in the Andaman Islands. The specific name honours the English military doctor and naturalist Francis Day (1829-1889) who was the Inspector-General of Fisheries in India. Day had described this blenny as Salarias alboguttatus in 1876 but this name was preoccupied by Salarias alboguttatus which had been described by Rudolf Kner in 1867.
Praealticus labrovittatus, the crenulate-lipped rockskipper, is a species of combtooth blenny found in the coral reefs in the western Pacific ocean. This species reaches a length of 4.2 centimetres (1.7 in) SL.
Praealticus margaritarius is a species of combtooth blenny found in the northwest Pacific ocean, around Japan. This species grows to a length of 10 centimetres (3.9 in) TL.
Praealticus margaritatus is a species of combtooth blenny found in the eastern central Pacific ocean, around Samoa. This species grows to a length of 5.5 centimetres (2.2 in) SL.
Praealticus multistriatus, the linedfin rockskipper , is a species of combtooth blenny found in the Pacific Ocean, around Tonga.
Praealticus natalis, the Christmas rockskipper, Natal blenny or the Natal rockskipper, is a species of combtooth blenny found in coral reefs around Christmas Island in the eastern Indian Ocean. This species grows to a length of 8 centimetres (3.1 in) TL.
Praealticus oortii is a species of combtooth blenny found in the eastern Indian Ocean from the Andaman Sea to Timor in the western Pacific. The identity of the person honoured by the specific name of this blenny was not specified but it is thought to be most likely to be the draftsman and illustrator Peter van Oort (1804-1834), who, as part of the Physics Commission for the Dutch East Indies, explored Java which is the type locality of this species.
Praealticus poptae, the Marianas rockskipper, is a species of combtooth blenny found in coral reefs in the western central Pacific ocean, around the Mariana Islands. This species grows to a length of 4.7 centimetres (1.9 in) SL. The specific name honours the Dutch ichthyologist and curator Canna Maria Louise Popta (1860-1929) of the Rijksmuseum van Natuurlijke Historie in Leiden.
