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.
The dwarf inanga is a galaxiid of the genus Galaxias, found in the North Island of New Zealand.
The slender sawtail catshark is a little-known species of catshark, part of the family Scyliorhinidae, endemic to northern Australia. It is found over the continental slope in 290–470 m (950–1,540 ft) on water. Growing to 34 cm (13 in) long, this shark has a slim gray body with four dark saddle markings below the dorsal fins and on the caudal fin, as well as a prominent crest of enlarged dermal denticles along the dorsal edge of the caudal fin. The slender sawtail catshark is not valued by fisheries but is taken as bycatch. The International Union for Conservation of Nature (IUCN) presently lacks enough information to assess its conservation status.
The elegant stubfoot toad or Pacific jambato frog is a species of toad in the family Bufonidae found in lowlands and Andean slopes of northwest Ecuador to 1,140 m (3,740 ft) asl and on the Gorgona Island, off southwest coast of Colombia. It was described by George Albert Boulenger in 1882 based on a specimen collected by Edward Whymper. It is known in Spanish as rana jambato del Pacífico or simply jambato del Pacífico.
Elliot's storm petrel is a species of seabird in the storm petrel family Hydrobatidae. The species is also known as the white-vented storm petrel. There are two subspecies, O. g. gracilis, which is found in the Humboldt Current off Peru and Chile, and O. g. galapagoensis, which is found in the waters around the Galápagos Islands. It is a sooty-black storm petrel with a white rump and a white band crossing the lower belly and extending up the midline of the belly. It has long legs which extend beyond the body in flight.
The gracile shrew mole is a species of mammal in the family Talpidae. It is endemic to China; populations known from Myanmar likely represent other species.
Troglohyphantes gracilis, one of several species to be occasionally called Kočevje subterranean spider, is a species of spider in the family Linyphiidae. It is endemic to Slovenia.
Odontesthes gracilis is a species of fish in the family Atherinidae. It is endemic to the Juan Fernandez Islands off Chile. It occurs around the mouths of caves, in inlets and around piers. This is a species which can be found in freshwater, brackish and marine waters. This species was described as Chirostoma gracile in 1898 by Franz Steindachner with the type locality given as Más a Tierra.
Coelus gracilis is a species of beetle in family Tenebrionidae. It is endemic to the United States.
Horsfieldia gracilis is a species of plant in the family Myristicaceae. It is a tree endemic to Borneo.
Pouteria gracilis is a species of plant in the family Sapotaceae. It is endemic to Peru.
Sloanea gracilis is a species of plant in the Elaeocarpaceae family. It is endemic to Suriname.
Acroporidae is a family of small polyped stony corals in the phylum Cnidaria. The name is derived from the Greek "akron" meaning "summit" and refers to the presence of a corallite at the tip of each branch of coral. They are commonly known as staghorn corals and are grown in aquaria by reef hobbyists.
Astreopora is a genus of stony corals in the Acroporidae family. Members of the genus are commonly known as star corals and there are seventeen species currently recognized.
The flathead chub is a species of fish in the carp family, Cyprinidae. It is the only member of the monotypic genus Platygobio. It is native to North America, where it is distributed throughout central Canada and the central United States.
Nehalennia gracilis, the sphagnum sprite, is a species of narrow-winged damselfly in the family Coenagrionidae. It is found in North America.
Astreopora myriophthalma, sometimes known as porous star coral, is a species of hard coral found in shallow water in the tropical Indian and Pacific Oceans. It is a common species with a wide range and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
Astreopora listeri is a species of hard coral found in shallow water in the tropical Indian and Pacific Oceans. It is an uncommon species with a wide range and is tolerant of turbid water, making it more resilient than some other corals to habitat disturbance. The International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
Astreopora incrustans, commonly known as starflower coral, is a species of hard coral found in the central Indo-Pacific, Japan and the East China Sea, the Solomons, Eastern Australia, and the Philippines. It is uncommon throughout its range.
Astreopora scabra is a species of hard coral found in Eastern Australia, the oceanic west Pacific, Micronesia, Polynesia, Papua New Guinea and American Samoa. It is an uncommon species with a relatively smaller range than many pacific coral species. The International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
