75 Endangered Species of the World
African bush elephant

The African bush elephant (Loxodonta africana), also known as the African savanna elephant, is one of two living African elephant species. It is the largest living terrestrial animal, with bulls reaching a shoulder height of up to 3.96 m (13.0 ft) and a body mass of up to 10.4 t (11.5 short tons). It is distributed across 37 African countries and inhabits forests, grasslands and woodlands, wetlands and agricultural land. Since 2021, it has been listed as Endangered on the IUCN Red List. It is threatened foremost by habitat destruction, and in parts of its range also by poaching for meat and ivory.

Bonobo

The bonobo, also historically called the pygmy chimpanzee and, less often, the dwarf or gracile chimpanzee, is an endangered great ape. It is one of the two species making up the genus Pan, the other being the common chimpanzee (Pan troglodytes). Although bonobos are not a subspecies of chimpanzee (Pan troglodytes), but rather a distinct species in their own right, both species are sometimes referred to collectively using the generalized term chimpanzees, or chimps. Taxonomically, the members of the chimpanzee/bonobo subtribe Panina (composed entirely by the genus Pan) are collectively termed panins.

Amur leopard

The Amur leopard (Panthera pardus orientalis) is a leopard subspecies native to the Primorye region of southeastern Russia and northern China. It is listed as Critically Endangered on the IUCN Red List. In 2007, only 19–26 wild leopards were estimated to survive in southeastern Russia and northeastern China. It was considered one of the rarest cats on Earth.As of 2015, fewer than 60 individuals were estimated to survive in Russia and China. Camera-trapping surveys conducted between 2014 and 2015 revealed 92 individuals in an 8,398 km2 (3,242 sq mi) large transboundary area along the Russian-Chinese border.
In 2019, it was reported that the population is close to 90 leopards.Results of genetic research indicate that the Amur leopard is genetically close to leopards in northern China and Korea, suggesting that the leopard population in this region became fragmented in the early 20th century. The North Chinese leopard was formerly recognised as a distinct subspecies P. p. japonensis, but was subsumed under the Amur leopard in 2017.

Chimpanzee

The chimpanzee (Pan troglodytes), also known as the common chimpanzee, or simply chimp, is a species of great ape native to the forest and savannah of tropical Africa. It has four confirmed subspecies and a fifth proposed subspecies. The chimpanzee and the closely related bonobo (sometimes called the “pygmy chimpanzee”) are classified in the genus Pan. Evidence from fossils and DNA sequencing shows that Pan is a sister taxon to the human lineage and is humans’ closest living relative.

Oligosoma salmo

The Chesterfield or Kapitia skink (Oligosoma salmo) is a species of skink found in New Zealand. Only discovered in 1994 and for years not recognised as a distinct species, it is endemic to a narrow 1 km strip of coastal vegetation on the West Coast of New Zealand, 15 km north of Hokitika. There are fewer than 200 individuals remaining in the wild. Oligosoma salmo is the only New Zealand skink with a prehensile tail, suggesting it was once arboreal and inhabited coastal forest, which was subsequently cleared for dairy farming. Following the partial destruction of its remaining habitat in 2018 by a cyclone, a small captive breeding population was established at Auckland Zoo.

Galapagos penguin

The Galápagos penguin (Spheniscus mendiculus) is a penguin endemic to the Galápagos Islands, Ecuador. It is the only penguin found north of the equator. Most inhabit Fernandina Island and the west coast of Isabela Island. The cool waters of the Humboldt and Cromwell Currents allow it to survive despite the tropical latitude. The Galápagos penguin is one of the banded penguins, the other species of which live mostly on the coasts of Africa and mainland South America. It is one of the smallest species of penguin in the world. Because of their warm environment, Galápagos penguins have developed techniques to stay cool. The feathers on their back, flippers, and head are black, and they have a white belly and a stripe looping from their eyes down to their neck and chin. Each penguin keeps only one mate, and breeds year-round. Their nests are typically in caves and crevices as protection against predators and the harsh environment. The Galápagos penguin has a lifespan of about 15 to 20 years, but due to predation, life expectancy in the wild could be significantly reduced.

Chinese giant salamander

The Chinese giant salamander (Andrias davidianus) is one of the largest salamanders and one of the largest amphibians in the world. It is fully aquatic and is endemic to rocky mountain streams and lakes in the Yangtze river basin of central China. Either it or a close relative has been introduced to Kyoto Prefecture in Japan and to Taiwan. It is considered critically endangered in the wild due to habitat loss, pollution, and overcollection, as it is considered a delicacy and used in traditional Chinese medicine. On farms in central China, it is extensively farmed and sometimes bred, although many of the salamanders on the farms are caught in the wild. It has been listed as one of the top-10 “focal species” in 2008 by the Evolutionarily Distinct and Globally Endangered project. The Chinese giant salamander is considered to be a “living fossil”. Although protected under Chinese law and CITES Appendix I, the wild population has declined by more than an estimated 80% since the 1950s. Although traditionally recognized as one of two living species of Andrias salamander in Asia, the other being the Japanese giant salamander, evidence indicates that the Chinese giant salamander may be composed of at least five cryptic species, further compounding each individual species’ endangerment.

Giant panda

The giant panda, also known as the panda bear (or simply the panda), is a bear native to South Central China. It is characterised by its bold black-and-white coat and rotund body. The name “giant panda” is sometimes used to distinguish it from the red panda, a neighboring musteloid. Though it belongs to the order Carnivora, the giant panda is a folivore, with bamboo shoots and leaves making up more than 99% of its diet. Giant pandas in the wild will occasionally eat other grasses, wild tubers, or even meat in the form of birds, rodents, or carrion. In captivity, they may receive honey, eggs, fish, yams, shrub leaves, oranges, or bananas along with specially prepared food.

Gorilla

Gorillas are herbivorous, predominantly ground-dwelling great apes that inhabit the tropical forests of equatorial Africa. The genus Gorilla is divided into two species: the eastern gorilla and the western gorilla, and either four or five subspecies. The DNA of gorillas is highly similar to that of humans, from 95 to 99% depending on what is included, and they are the next closest living relatives to humans after chimpanzees and bonobos.

Gulf sturgeon

The Gulf sturgeon is a subspecies of sturgeon that lives in the Gulf of Mexico and some rivers draining into it. The Gulf sturgeon was first recognized as a separate subspecies in 1955. The nominate subspecies is the Atlantic sturgeon, A. o. oxyrinchus. The Gulf sturgeon is listed as threatened under the United States Endangered Species Act, having been listed in 1991. Critical habitat, reflecting the current range of the subspecies, has been designated. The historical range is thought to have been from the Suwannee River on the western coast of Florida to the Mississippi River, and marine waters of the central and eastern portions of the Gulf of Mexico. Three sturgeon species in genus Scaphirhynchus share river territory with the Gulf sturgeon; none of these is anadromous.

Irrawaddy dolphin

The Irrawaddy dolphin (Orcaella brevirostris) is a euryhaline species of oceanic dolphin found in discontinuous subpopulations near sea coasts and in estuaries and rivers in parts of the Bay of Bengal and Southeast Asia. It closely resembles the Australian snubfin dolphin (of the same genus, Orcaella) and was not described as a separate species until 2005. It has a slate blue to a slate gray color and are a part of genus Orcaella which is also known as snubfin dolphins. Although found in much of the riverine and marine zones of South and Southeast Asia, the only concentrated lagoon populations are found in Chilika Lake in Odisha, India and Songkhla Lake in southern Thailand.

Leatherback sea turtle

The leatherback sea turtle (Dermochelys coriacea), sometimes called the lute turtle or leathery turtle or simply the luth, is the largest of all living turtles and the heaviest non-crocodilian reptile, reaching lengths of up to 2 metres and weights of 600 kg. It is the only living species in the genus Dermochelys and family Dermochelyidae. It can easily be differentiated from other modern sea turtles by its lack of a bony shell; instead, its carapace is covered by oily flesh and flexible, leather-like skin, for which it is named.

Blackbuck

The blackbuck (Antilope cervicapra), also known as the Indian antelope, is an antelope native to India and Nepal. It inhabits grassy plains and lightly forested areas with perennial water sources. It stands up to 74 to 84 cm (29 to 33 in) high at the shoulder. Males weigh 20–57 kg (44–126 lb), with an average of 38 kg (84 lb). Females are lighter, weighing 20–33 kg (44–73 lb) or 27 kg (60 lb) on average. Males have 35–75 cm (14–30 in) long, ringed horns, though females may develop horns as well. The white fur on the chin and around the eyes is in sharp contrast with the black stripes on the face. The coats of males show a two-tone colouration; while the upper parts and outsides of the legs are dark brown to black, the underparts and the insides of the legs are white. Females and juveniles are yellowish fawn to tan. The blackbuck is the sole living member of the genus Antilope and was scientifically described by Carl Linnaeus in 1758. Two subspecies are recognized.

North Atlantic right whale

The North Atlantic right whale (Eubalaena glacialis) is a baleen whale, one of three right whale species belonging to the genus Eubalaena, all of which were formerly classified as a single species. Because of their docile nature, their slow surface-skimming feeding behaviors, their tendencies to stay close to the coast, and their high blubber content (which makes them float when they are killed, and which produced high yields of whale oil), right whales were once a preferred target for whalers.
At present, they are among the most endangered whales in the world, and they are protected under the U.S. Endangered Species Act and Marine Mammal Protection Act and Canada’s Species at Risk Act. There are fewer than 366 individuals in existence in the western North Atlantic Ocean—they migrate between feeding grounds in the Labrador Sea and their winter calving areas off Georgia and Florida, an ocean area with heavy shipping traffic. In the eastern North Atlantic, on the other hand—with a total population reaching into the low teens at most—scientists believe that they may already be functionally extinct. Vessel strikes and entanglement in fixed fishing gear, which together account for nearly half of all North Atlantic right whale mortality since 1970, are their two greatest threats to recovery.

Red panda

The red panda (Ailurus fulgens) is a carnivoran native to the eastern Himalayas and southwestern China. It is listed as Endangered on the IUCN Red List because the wild population is estimated at fewer than 10,000 mature individuals and continues to decline due to habitat loss and fragmentation, poaching, and inbreeding depression. Despite its name, it is not closely related to the giant panda.

San Joaquin kit fox

The endangered San Joaquin kit fox (Vulpes macrotis mutica) was formerly very common in the San Joaquin Valley and through much of Central California. Its 1990 population was estimated to be 7,000. This subspecies is still endangered, after nearly 50 years of being on the Endangered Species List. Officially this subspecies was listed March 3, 1967. On September 26, 2007, Wildlands Inc. announced the designation of the 684-acre (2.77 km2) Deadman Creek Conservation Bank, which is intended specifically to protect habitat of the San Joaquin kit fox. However, the population continues to decline mostly due to heavy habitat loss. Other factors include competition from red fox, and the extermination of the gray wolf from California has left the coyote as the dominant meso-predator in kit fox territory bringing an imbalance in ecosystem relationships. Sarcoptic Mange has also constituted a significant threat, specifically to the Bakersfield population of the subspecies, with 15 confirmed cases reported by the end of 2014.

Yangtze finless porpoise

The Yangtze finless porpoise (Neophocaena asiaeorientalis) is a species of toothed whale in the family Phocoenidae. It is endemic to the Yangtze River in China, making it the country’s only known freshwater cetacean following the possible extinction of the baiji (Lipotes vexillifer). The Yangtze finless porpoise is considered critically endangered and it is estimated that only about 1,000 remain. This small toothed whale faces many of the same threats that caused the baiji dolphin to possibly become extinct. The Yangtze River has a high traffic rate of human activity causing population declines due to illegal fishing, pollution, vessel traffic, and dam construction. Due to the rapidly declining population of the species, the Chinese Government and conservation charities are working to help save it from extinction.

Baiji

The baiji is a possibly extinct species of freshwater dolphin. It is thought to be the first dolphin species driven to extinction due to the impact of humans. Despite being listed as “critically endangered: possibly extinct” by the IUCN, this dolphin has not been seen in almost 20 years and several surveys of the Yangtze have failed to find it. In China, the species is also called the Chinese river dolphin, Yangtze river dolphin, Yangtze dolphin and whitefin dolphin.

Black rhinoceros

The black rhinoceros or hook-lipped rhinoceros (Diceros bicornis) is a species of rhinoceros, native to eastern and southern Africa including Angola, Botswana, Kenya, Malawi, Mozambique, Namibia, South Africa, Eswatini, Tanzania, Zambia, and Zimbabwe. Although the rhinoceros is referred to as black, its colours vary from brown to grey.
The other African rhinoceros is the white rhinoceros (Ceratotherium simum). The word “white” in the name “white rhinoceros” is often said to be a misinterpretation of the Afrikaans word wyd (Dutch wijd) meaning wide, referring to its square upper lip, as opposed to the pointed or hooked lip of the black rhinoceros. These species are now sometimes referred to as the square-lipped (for white) or hook-lipped (for black) rhinoceros.The species overall is classified as critically endangered (even though the south-western black rhinoceros is classified as near threatened). Three subspecies have been declared extinct, including the western black rhinoceros, which was declared extinct by the International Union for Conservation of Nature (IUCN) in 2011.

Black-footed ferret

The black-footed ferret (Mustela nigripes), also known as the American polecat or prairie dog hunter, is a species of mustelid native to central North America.
The black-footed ferret is roughly the size of a mink and is similar in appearance to the European polecat and the Asian steppe polecat. It is largely nocturnal and solitary, except when breeding or raising litters. Up to 90% of its diet is composed of prairie dogs.The species declined throughout the 20th century, primarily as a result of decreases in prairie dog populations and sylvatic plague. It was declared extinct in 1979, but a residual wild population was discovered in Meeteetse, Wyoming in 1981. A captive-breeding program launched by the United States Fish and Wildlife Service resulted in its reintroduction into eight western US states, Canada, and Mexico from 1991 to 2009. As of 2011, over 1,000 mature, wild-born individuals are in the wild across 18 populations, with four self-sustaining populations in South Dakota (two), Arizona, and Wyoming. It was first listed as “endangered” in 1982, then listed as “extinct in the wild” in 1996 before being downgraded back to “endangered” in the IUCN Red List in 2008. In February 2021, the first successful clone of a black-footed ferret, a female named Elizabeth Ann, was introduced to the public.

Borneo elephant

The Borneo elephant, also called the Borneo pygmy elephant, is a subspecies of Asian elephant (Elephas maximus) that inhabits northeastern Borneo, in Indonesia and Malaysia. Its origin remains the subject of debate. A definitive subspecific classification as Elephas maximus borneensis awaits a detailed range-wide morphometric and genetic study. Since 1986, the Asian elephant has been listed as Endangered on the IUCN Red List as the population has declined by at least 50% over the last three generations, estimated to be 60–75 years. It is pre-eminently threatened by loss, degradation and fragmentation of habitat.

Ivory-billed woodpecker

The ivory-billed woodpecker (Campephilus principalis) is a possibly-extinct woodpecker native to the bottomland hardwood forests and temperate coniferous forests of the Southern United States and Cuba. Habitat destruction and hunting have reduced populations so thoroughly that the species is listed as Critically Endangered on the IUCN Red List, and as “definitely or probably extinct” by the American Birding Association. The last universally accepted sighting of an American ivory-billed woodpecker occurred in Louisiana in 1944, and the last universally accepted sighting of a Cuban ivory-billed woodpecker occurred in 1987; sporadic reports of sightings and other evidence of the birds’ persistence have continued since then. In the 21st century, reported sightings and analyses of audio and visual recordings have been published in peer-reviewed scientific journals as evidence that the species persists in Arkansas, Louisiana, and Florida. Various land purchases and habitat restoration efforts have been initiated in areas where sightings and other evidence have suggested a relatively high probability the species exists, to protect any surviving individuals. In September 2021, the U.S. Fish and Wildlife Service proposed that the species be declared extinct, pending a 60-day period of public comment ending November 29, 2021. The IUCN has not changed its assessment of the species.

Kashmir stag

The Kashmir stag (Cervus hanglu hanglu), also called hangul, is a subspecies of Central Asian red deer endemic to Kashmir, India. It is found in dense riverine forests in the high valleys and mountains of the Kashmir Valley and northern Chamba district in Himachal Pradesh. In Kashmir, it is found in the Dachigam National Park where it receives protection but elsewhere it is more at risk. In the 1941s, the population was between 3000 and 5000 individuals, but since then habitat destruction, over-grazing by domestic livestock and poaching have reduced population dramatically.

Maui dolphin

Māui dolphin, Maui’s dolphin, or popoto (Cephalorhynchus hectori maui) is a subspecies of the Hector’s dolphin (Cephalorhynchus hectori)—New Zealand’s only endemic cetacean species. Māui dolphins are only found off the west coast of New Zealand’s North Island, and are now one of the rarest and smallest dolphin subspecies globally. A 2021 report issued by the New Zealand government suggests the population rests at 54 individuals, but when taking into account recent mortalities, the population could sit at less than 50 individuals.

Whooping crane

Named for its whooping sound, the whooping crane (Grus americana), is the tallest North American bird. It is an endangered crane species. Along with the sandhill crane (Antigone canadensis), it is one of only two crane species native to North America. The whooping crane’s lifespan is estimated to be 22 to 24 years in the wild. After being pushed to the brink of extinction by unregulated hunting and loss of habitat to just 21 wild and two captive whooping cranes by 1941, conservation efforts have led to a limited recovery. The total number of cranes in the surviving migratory population, plus three reintroduced flocks and in captivity, now exceeds 800 birds.
