Critically endangered in the context of "Glacial refugium"

The eastern gorilla (Gorilla beringei) is a critically endangered species of the genus Gorilla and the largest living primate. At present, the species is subdivided into two subspecies. There are 6,800 eastern lowland gorillas or Grauer's gorillas (G. b. graueri) and 1,000 mountain gorillas (G. b. beringei). Illegal hunting threatens the species.

The Bornean orangutan (Pongo pygmaeus) is an orangutan species endemic to the island of Borneo. It belongs to the only genus of great apes native to Asia and is the largest of the three Pongo species. It has a coarse, reddish coat and up to 1.5 m (4 ft 11 in) long arms. It is sexually dimorphic — males are larger than females and develop large cheek pads (flanges), for example.

The Bornean orangutan inhabits Borneo lowland rain forests and Borneo montane rain forests up to an elevation of 1,500 m (4,900 ft). Its diet includes fruits, seeds, flowers, bird eggs, sap and vines. It is highly intelligent, displaying tool use and distinct cultural patterns. It is critically endangered, with deforestation, palm oil plantations, and hunting posing a serious threat to its survival.

The Sumatran orangutan (Pongo abelii) is one of the three species of orangutans. Critically endangered, and found only in the north of the Indonesian island of Sumatra, it is rarer than the Bornean orangutan but more common than the recently identified Tapanuli orangutan, also found in Sumatra. Its common name is based on two separate local words, orang 'people; person' and hutan 'forest', derived from Malay, and translates as 'person of the forest'.

The Tapanuli orangutan (Pongo tapanuliensis) is a species of orangutan restricted to South Tapanuli in the island of Sumatra in Indonesia. It is one of three known living species of orangutan, alongside the Sumatran orangutan (P. abelii), found farther northwest on the island, and the Bornean orangutan (P. pygmaeus). It was described as a distinct species in 2017. As of 2018, there are roughly 800 individuals of this species and it is currently on the critically endangered species list.

A crocodile (family Crocodylidae) or true crocodile is a large, semiaquatic reptile that lives throughout the tropics in Africa, Asia, the Americas and Australia. The term "crocodile" is sometimes used more loosely to include all extant members of the order Crocodilia, which includes the alligators and caimans (both members of the family Alligatoridae), the gharial and false gharial (both members of the family Gavialidae) as well as other extinct taxa.

Crocodile size, morphology, behaviour and ecology differ among species. However, they have many similarities in these areas as well. All crocodiles are semiaquatic and tend to congregate in freshwater habitats such as rivers, lakes, wetlands and sometimes in brackish water and saltwater. They are carnivorous animals, feeding mostly on vertebrates such as fish, reptiles, birds and mammals, and sometimes on invertebrates such as molluscs and crustaceans, depending on species and age. All crocodiles are tropical species that, unlike alligators, are very sensitive to cold. Many species are at the risk of extinction, some being classified as critically endangered.

The Marsican brown bear (Ursus arctos arctos, formerly Ursus arctos marsicanus), also known as the Apennine brown bear, is a critically endangered population of the Eurasian brown bear, with a range restricted to the Parco Nazionale d'Abruzzo, Lazio e Molise, and the surrounding region in Italy. The Marsican brown bear differs slightly from other brown bears in its appearance and hibernation techniques. The bear's popular name is derived from Marsica, a historic area of the modern-day region of Abruzzo where the bear has long had a significant presence.

With their existence dwindling, the Italian government has recently begun to stress their conservation. The park has become a sanctuary dedicated to animals such as the Marsican brown bear, with hopes of rekindling the large, yet isolative bears' once-thriving existence. Debate exists as to whether it should be considered a subspecies or a taxon of its own.

An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular region. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. 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 or harvesting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration.

Human activity is a significant factor in causing some species to become endangered.

A camel (from Latin: camelus and Ancient Greek: κάμηλος (kamēlos) from Ancient Semitic: gāmāl) is an even-toed ungulate in the genus Camelus that bears distinctive fatty deposits known as "humps" on its back. Camels have long been domesticated and, as livestock, they provide food (camel milk and meat) and textiles (fiber and felt from camel hair). Camels are working animals especially suited to their desert habitat and are a vital means of transport for passengers and cargo. There are three surviving species of camel. The one-humped dromedary makes up 94% of the world's camel population, and the two-humped Bactrian camel makes up 6%. The wild Bactrian camel is a distinct species that is not ancestral to the domestic Bactrian camel, and is now critically endangered, with fewer than 1,000 individuals.

The word camel is also used informally in a wider sense, where the more correct term is "camelid", to include all seven species of the family Camelidae: the true camels (the above three species), along with the "New World" camelids: the llama, the alpaca, the guanaco, and the vicuña, which belong to the separate tribe Lamini. Camelids originated in North America during the Eocene, with the ancestor of modern camels, Paracamelus, migrating across the Bering land bridge into Asia during the late Miocene, around 6 million years ago.

The Javan rhinoceros (Rhinoceros sondaicus), Javan rhino, Sunda rhinoceros or lesser one-horned rhinoceros is a critically endangered member of the genus Rhinoceros, of the rhinoceros family Rhinocerotidae, and one of the five remaining extant rhinoceros species in South Asia and Africa. It has a plate-like skin with protective folds and is one of the smallest rhinoceros species with a body length of 3.1–3.2 m (10–10 ft) and a 1.4–1.7 m (4 ft 7 in – 5 ft 7 in) long tail. The heaviest specimens weigh around 2,300 kg (5,100 lb). Its horn is usually shorter than 25 cm (9.8 in).

Up until the mid-19th to about the early 20th century, the Javan rhinoceros had ranged beyond the islands of Java and Sumatra and onto the mainland of Southeast Asia and Indochina, northwest into East India, Bhutan, and the south of China. Today, it is the rarest of all rhinoceros, and among the rarest of all living animal species, with only one currently known wild population, and no individuals successfully kept in captivity. It is among the rarest large mammals in the world with a population of approximately 74 rhinos within Ujung Kulon National Park, at the far western tip of Java, Indonesia.

Wollemia is a genus of coniferous trees in the family Araucariaceae, endemic to Australia. It represents one of only three living genera in the family, alongside Araucaria and Agathis (being more closely related to the latter). The genus has only a single known species, Wollemia nobilis, commonly known as the Wollemi pine (though it is not a true pine) which was discovered in 1994 in a temperate rainforest wilderness area of the Wollemi National Park in New South Wales. It was growing in a remote series of narrow, steep-sided, sandstone gorges 150 km (93 mi) north-west of Sydney. The genus is named after the National Park.

The Wollemi pine is classified as critically endangered (CR) on the IUCN's Red List, and is legally protected in Australia. After it was discovered that the trees could be successfully cloned, new specimens were planted widely around the world in regions with mild temperate climates.
