A hybrid orangutan or cocktail orangutan is usually an orangutan derived from interbreeding between any of the three Orangutan species: Bornean (Pongo pygmaeus), Sumatran (Pongo abelii) and Tapanuli (Pongo tapanuliensis), but the term "hybrid orangutan" could also refer to hybrids of the three known Bornean subspecies. [1] As of 2015, there are approximately 134 living Bornean x Sumatran hybrid orangutans in captivity. [2]

Hybrids in captivity

Before Bornean and Sumatran orangutans were described as separate species in the early 2000s, orangutans from differing species were paired in captivity, and produced hybrid offspring. In 1985, the Orangutan SSP within the American Association of Zoos and Aquariums (AZA) issued a moratorium on the breeding of Sumatran x Bornean hybrids. [3] In 1994, it was recommended that those hybrids should be sterilised if they are housed in a situation where breeding may happen. [4] The Tapanuli orangutan was not described as a separate species until 2017, which led to some interbreeding between Sumatran and Tapanuli orangutans in captivity. In 2022, an orangutan named Bubbles, who was previously thought to be Sumatran, was found to be Tapanuli, making her offspring hybrids of both the Sumatran and Tapanuli species. [5] It is possible that there are still many undiscovered Sumatran x Tapanuli hybrids in captivity. Bornean orangutans have three known subspecies: P. p morio, P. p pygmaeus and P.p wurmbii. In captivity, these subspecies are housed together and not managed at a subspecies level. [6] After many generations of hybridisation, there are likely very few “pure” individuals left.

Hybrids in Borneo

From 1971 to 1985, 90 orphaned or displaced orangutans rescued from illegal wildlife trade were released into Tanjung Puting National Park in Central Kalimantan. A subsequent genetic survey determined that at least two orangutans, captured in a different region and therefore not native to the park, had prolifically interbred with the local native apes, and produced at least 22 hybridized descendants. [7] Their offspring contributes to fears that interbreeding of subspecies leads to "hybrid vigor", in which "offspring reap the benefits of their parents' individual qualities".

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.

<span class="mw-page-title-main">Orangutan</span> Genus of Asian apes

Orangutans are great apes native to the rainforests of Indonesia and Malaysia. They are now found only in parts of Borneo and Sumatra, but during the Pleistocene they ranged throughout Southeast Asia and South China. Classified in the genus Pongo, orangutans were originally considered to be one species. From 1996, they were divided into two species: the Bornean orangutan and the Sumatran orangutan. A third species, the Tapanuli orangutan, was identified definitively in 2017. The orangutans are the only surviving species of the subfamily Ponginae, which diverged genetically from the other hominids between 19.3 and 15.7 million years ago.

<span class="mw-page-title-main">Primate</span> Order of mammals

Primates are a diverse order of mammals. They are divided into the strepsirrhines, which include the lemurs, galagos, and lorisids, and the haplorhines, which include the tarsiers and the simians. Primates arose 85–55 million years ago first from small terrestrial mammals, which adapted to living in the trees of tropical forests: many primate characteristics represent adaptations to life in this challenging environment, including large brains, visual acuity, color vision, a shoulder girdle allowing a large degree of movement in the shoulder joint, and dextrous hands. Primates range in size from Madame Berthe's mouse lemur, which weighs 30 g (1 oz), to the eastern gorilla, weighing over 200 kg (440 lb). There are 376–524 species of living primates, depending on which classification is used. New primate species continue to be discovered: over 25 species were described in the 2000s, 36 in the 2010s, and three in the 2020s.

<span class="mw-page-title-main">Ape</span> Branch of primates

Apes are a clade of Old World simians native to sub-Saharan Africa and Southeast Asia, which together with its sister group Cercopithecidae form the catarrhine clade, cladistically making them monkeys. Apes do not have tails due to a mutation of the TBXT gene. In traditional and non-scientific use, the term "ape" can include tailless primates taxonomically considered Cercopithecidae, and is thus not equivalent to the scientific taxon Hominoidea. There are two extant branches of the superfamily Hominoidea: the gibbons, or lesser apes; and the hominids, or great apes.

The Sumatran rhinoceros, also known as the Sumatran rhino, hairy rhinoceros or Asian two-horned rhinoceros, is a rare member of the family Rhinocerotidae and one of five extant species of rhinoceros; it is the only extant species of the genus Dicerorhinus. It is the smallest rhinoceros, although it is still a large mammal; it stands 112–145 cm (44–57 in) high at the shoulder, with a head-and-body length of 2.36–3.18 m and a tail of 35–70 cm (14–28 in). The weight is reported to range from 500–1,000 kg (1,100–2,200 lb), averaging 700–800 kg (1,500–1,800 lb). Like both African species, it has two horns; the larger is the nasal horn, typically 15–25 cm (5.9–9.8 in), while the other horn is typically a stub. A coat of reddish-brown hair covers most of the Sumatran rhino's body.

Campbell's dwarf hamster is a species of hamster in the genus Phodopus. It was given its common name by Oldfield Thomas in honor of Charles William Campbell, who collected the first specimen in Mongolia on July 1, 1902. It is distinguished from the closely related Djungarian hamster as it has smaller ears and no dark fur on its crown. Campbell's dwarf hamster typically has a narrow dorsal stripe compared to the Djungarian hamster and grey fur on the stomach. This hamster may be raised in captivity and kept as a small pet.

Captive breeding, also known as captive propagation, is the process of keeping plants or animals in controlled environments, such as wildlife reserves, zoos, botanic gardens, and other conservation facilities. It is sometimes employed to help species that are being threatened by the effects of human activities such as climate change, habitat loss, fragmentation, overhunting or fishing, pollution, predation, disease, and parasitism.

The Sumatran orangutan 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" and "hutan" ("forest"), derived from Malay, and translates as 'person of the forest'.

<span class="mw-page-title-main">Behavioral enrichment</span>

Behavioral enrichment is an animal husbandry principle that seeks to enhance the quality of captive animal care by identifying and providing the environmental stimuli necessary for optimal psychological and physiological well-being. Enrichment can either be active or passive, depending on whether it requires direct contact between the animal and the enrichment. A variety of enrichment techniques are used to create desired outcomes similar to an animal's individual and species' history. Each of the techniques used is intended to stimulate the animal's senses similarly to how they would be activated in the wild. Provided enrichment may be seen in the form of auditory, olfactory, habitat factors, food, research projects, training, and objects.

The Bornean orangutan is a species of orangutan endemic to the island of Borneo. Together with the Sumatran orangutan and Tapanuli orangutan, it belongs to the only genus of great apes native to Asia. Like the other great apes, orangutans are highly intelligent, displaying tool use and distinct cultural patterns in the wild. Orangutans share approximately 97% of their DNA with humans. Also called mias by the local population, the Bornean orangutan is a critically endangered species, with deforestation, palm oil plantations, and hunting posing a serious threat to its continued existence.
