The Malayan tapir (Tapirus indicus), also called the Asian tapir, is the largest of the five species of tapir and the only one native to Asia. The scientific name refers to the East Indies, the species' natural habitat. In the Malay language, the tapir is commonly referred to as cipan, tenuk or badak tampung.
The animal is easily identified by its markings, most notably the light-colored patch that extends from its shoulders to its rear end. The rest of its hair is black, except for the tips of its ears, which, as with other tapirs, are rimmed with white. This pattern is for camouflage; the disrupted coloration makes it more difficult to recognize it as a tapir, and other animals may mistake it for a large rock rather than prey when it is lying down to sleep.
Malayan tapirs grow 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 stand 90 to 110 cm (2 ft 11 in to 3 ft 7 in) tall. They typically weigh between 250 and 320 kg (550 and 710 lb), although some adults can weigh up to 540 kg (1,190 lb). The females are usually larger than the males. Like the other types of tapir, they have small, stubby tails and long, flexible proboscises. They have 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.
They have a large sagittal crest, a bone running along the middle of the skull that is necessary for muscle attachment. They also have unusually positioned orbits, an unusually shaped cranium with the frontal bones elevated, and a retracted nasal incision. All of these modifications to the normal mammal skull are, of course, to make room for 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.
Malayan tapirs have very poor eyesight, making them rely greatly on their excellent sense of smell and hearing to go about in their everyday lives. They have small, beady eyes with brown irises on either side of their faces. 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 when 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.
