The Malayan tapir (Tapirus indicus), also called Asian tapir, Asiatic tapir, oriental tapir, Indian tapir, piebald tapir, or black-and-white tapir, is the only living Tapir species outside of the Americas. It is native to Southeast Asia from the Malay Peninsula to Sumatra. It has been listed as Endangered on the IUCN Red List since 2008, as the population is estimated to comprise fewer than 2,500 mature individuals.^[1]

The Malayan tapir is easily identified by its markings, most notably the light-colored patch that extends from its shoulders to its hindquarters. It is covered in black hair, except for the tips of its ears, which, as with other tapirs, are rimmed with white. The pattern is for

The Malayan tapir is the largest of the four extant tapir species and grows to between 1.8 and 2.5 m (5 ft 11 in and 8 ft 2 in) in length, not counting a stubby tail of only 5 to 10 cm (2.0 to 3.9 in) in length, and stands 90 to 110 cm (2 ft 11 in to 3 ft 7 in) tall. It typically weighs between 250 and 320 kg (550 and 710 lb), although some adults can weigh up to 540 kg (1,190 lb).[9]^[10][11][12] The females are usually larger than the males. Like other tapir species, it has a small, stubby tail and a long, flexible proboscis. It has four toes on each front foot and three toes on each back foot. The Malayan tapir has rather poor eyesight, but excellent hearing and sense of smell.

It has a large sagittal crest, a bone running along the middle of the skull that is necessary for muscle attachment. It also possesses unusually positioned orbits, an unusually shaped cranium with the frontal bones elevated, and a retracted nasal incision. These adaptations evolved to support the proboscis. This proboscis caused a retraction of bones and cartilage in the face during the evolution of the tapir, and even caused the loss of some cartilages, facial muscles, and the bony wall of the nasal chamber.

Vision

Malayan tapirs have very poor eyesight, instead relying on excellent senses of smell and hearing. The eyes are small with brown irises, positioned on the sides of the face. Their eyes are often covered in a blue haze, which is corneal cloudiness thought to be caused by repetitive exposure to light. Corneal cloudiness is a condition in which the cornea starts to lose its transparency. The cornea is necessary for the transmitting and focusing of outside light as it enters the eye, and cloudiness can cause vision loss. This causes the Malayan tapir to have very inadequate vision, both on land and in water, where they spend the majority of their time. Also, as these tapirs are most active at night and since they have poor eyesight, it is harder for them to search for food and avoid predators in the dark.^[13][14]

Colour variation

Two melanistic Malayan tapirs were observed in Jerangau Forest Reserve in Malaysia in 2000.^[15] A black Malayan tapir was also recorded in Tekai Tembeling Forest Reserve in Pahang state in 2016.^[16]

Distribution and habitat

The Malayan tapir is distributed throughout the tropical lowland rainforests of Southeast Asia, including Sumatra in Indonesia, Peninsular Malaysia, Myanmar, and Thailand. Populations in Sabah in Borneo may have persisted until recently but are now considered extinct.^[17]

Malayan tapirs are primarily solitary, marking out large tracts of land as their

The gestation period of the Malayan tapir is about 390–395 days, after which a single calf is born that weighs around 6.8 kg (15 lb). Malayan tapirs are the largest of the four tapir species at birth and in general grow more quickly than their relatives.^[19] Young tapirs of all species have brown hair with white stripes and spots, a pattern that enables them to hide effectively in the dappled light of the forest. This baby coat fades into adult coloration between four and seven months after birth. Weaning occurs between six and eight months of age, at which time the babies are nearly full-grown, and the animals reach sexual maturity around age three. Breeding typically occurs in April, May or June, and females generally produce one calf every two years. Malayan tapirs can live up to 30 years, both in the wild and in captivity.^{[citation needed]}

Predators

Because of its size, the Malayan tapir has few natural predators, and even reports of killings by tigers (Panthera tigris),^[20] leopards (Panthera pardus), or dholes (Cuon alpinus) are scarce.

Threats

The main threat to the Malayan tapir is loss and
