The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists are produced by countries and organizations, which assess the risk of extinction to species within a political management unit.
The ring-billed gull is a medium-sized gull. The genus name is from Latin Larus which appears to have referred to a gull or other large seabird. The specific delawarensis refers to the Delaware River.
Gervais's beaked whale, sometimes known as the Antillean beaked whale, Gulf Stream beaked whale, or European beaked whale is the most frequently stranding type of mesoplodont whale off the coast of North America. It has also stranded off South America and Africa.
The Nassau grouper is one of the large number of perciform fishes in the family Serranidae commonly referred to as groupers. It is the most important of the groupers for commercial fishery in the West Indies, but has been endangered by overfishing.
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 are in use at international, multi-country, national and local levels, as well as for consumer use such as sustainable seafood advisory lists and certification. The two international systems are by the International Union for Conservation of Nature (IUCN) and The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
The Atlantic whitefish is a coregonine fish inhabiting some freshwater lakes within Nova Scotia, Canada. It is known to survive only in the Petite Rivière watershed as landlocked populations. Earlier it was also found in the Tusket and Annis rivers of Nova Scotia. Those populations were anadromous, migrating to the estuary to feed while breeding in freshwater.
The sailfin roughshark is a species of dogfish shark in the family Oxynotidae, found in the eastern North Atlantic from Scotland to Senegal between latitudes 61°N and 11°N, at depths of between 265 and 720 m. Its length is up to 1.2 m (3.9 ft).
The white-browed hawk is a species of bird of prey in subfamily Accipitrinae, the "true" hawks, of family Accipitridae. It is found Bolivia, Brazil, and Peru.
The red-necked aracari or red-necked araçari is a near-passerine bird in the toucan family Ramphastidae. It is found in Bolivia and Brazil.
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration.
Saccopharynx ampullaceus, referred to as the gulper eel, gulper, taillight gulper or pelican-fish, is an ocean-dwelling eel found in the North Atlantic Ocean. They are found up to a depth of 3,000 m (9,800 ft). These fish are rarely observed, so little information is currently known about their habits or full distribution.
Saccopharynx lavenbergi is a species of gulper eel, also known as the whiptail gulper. This fish is known for its large mouth and long whiplike tail. This species is not commonly found in the wild, with fewer than twenty sightings over 30 years of ROV operation by MBARI. Even though it has rarely been sighted, this gulper eel was chosen to be the logo for MBARI.
The Spanish ling, also called the Mediterranean ling and even blue ling, is a species of fish in the family Lotidae.
Scomberesox simulans, the dwarf saury, is a species of ray-finned fish within the family Scomberesocidae, found in the Atlantic and Indian Ocean. It inhabits tropical and subtropical waters near the surface as a pelagic-oceanic species, migrating as the ocean warms in the spring and summer. It mainly feeds on planktonic organisms. The maximum length recorded was 13 centimeters in length, although the species is most commonly found at 9-10 centimeters in length. It is often confused as the juvenile form of the Atlantic saury.
The island cowfish is a species of ray-finned fish within the family Ostraciidae. The species occurs in the eastern Atlantic near Azores, Saint Helena and Ascension Island, Ghana, and Angola, with some individuals reported from Sao Tome Island. It lives in shallow waters 3-25 meters below the ocean surface over rocks, rubble, sand, and on shallow reef substrate near islands. It grows to a length of 50 centimeters.
Zu elongatus, the taper-tail ribbonfish, is a species of ray-finned fish within the family Trachipteridae. The species distribution is likely in temperate and tropical waters in all oceans, but has only been occurred in the Atlantic and Pacific off Namibia, the western Cape coast, and New Zealand. It inhabits mesopelagic waters up to 1200 meters below sea level. Other common names include the scalloped dealfish and spitsstert-lintvis in Afrikaans.
Saccopharynx berteli is a species of ray-finned fish within the family Saccopharyngidae. It is known from a single holotype collected from the central Pacific Ocean through an open fishing net at a depth of 1,100 metres (3,600 ft) in 1977. The individual caught was an immature male with a length of 89.5 centimetres (35.2 in). It has been classified as a 'Data deficient' species by the IUCN Red List as there is little information regarding its population, ecology, distribution, and potential threats.
Palinurus gilchristi, the southern spiny lobster, is a species of spiny lobster within the family Palinuridae.
Choranthias tenuis, the threadnose bass, is a species of ray-finned fish within the family Serranidae. Its distribution covers the western Atlantic near areas such as Bermuda, North Carolina, Florida, Texas, Georgia, South Carolina, Mississippi, Venezuela, Guyana, southeastern Gulf of Mexico, Yucatan, Puerto Rico, and the southern Caribbean, where it lives in subtropical waters over hard bottoms with large rocks that allow for micro habitats. The depths the species occurs is 55 to 915 meters, however individuals are more commonly found at depths less than 150 meters. It is commonly found at 8 centimeters in length and a maximum of 9 centimeters. It feeds on plankton and swims in schools.
Saccopharynx paucovertebratis is a species of ray-finned fish within the family Saccopharyngidae. The species is known from a single a single holotype collected from a fishing trawl west of Madeira in the Atlantic Ocean at a depth up to 1,700 m (5,600 ft) in 1931. The holotype was measured at 30.5 centimetres (12 in) in length. The IUCN Red List has assessed the species as 'Data deficient' as there is there is little information regarding population, ecology, distribution, and potential threats.
