Malayan tapir: The rainforest gardener with a remarkable nose

With a body resembling a giant pig and an elongated snout similar to an elephant’s trunk, Malayan tapirs (Tapirus indicus) are among the most distinctive mammals on Earth.

They are the largest of the four living tapir species and the only one found outside the Americas. Today, Malayan tapirs live in tropical forests across parts of southern Thailand, southern Myanmar, Peninsular Malaysia, and the Indonesian island of Sumatra.

Their long, flexible noses help them navigate dense vegetation and grasp leaves, shoots, and fruit. As they forage and move through the forest, they can also transport seeds, helping shape the plant communities around them.

Camouflage in black and white

Few mammals have a coat quite like the Malayan tapir. Black fur covers the head, shoulders, and legs, while a broad patch of white stretches across the middle and rear of the body.

Rather than making the animal more conspicuous, this sharply contrasting pattern helps break up its outline among the shadows, vegetation, and uneven terrain of the forest. When a tapir lies down, potential predators may have difficulty recognizing it as an animal at all.

Malayan tapirs measure about 1.8 to 2.5 meters (5.9–8.2 ft) long, excluding their short tail, and stand around 90 to 110 centimeters (2.9–3.6 ft) tall. Adults typically weigh between 250 and 320 kilograms (550–710 lb), although some individuals can grow considerably heavier. Females are usually larger than males.

Like other tapirs, they have four toes on each front foot and three on each hind foot, helping support their heavy bodies as they move through muddy forests, riverbanks, and steep slopes.

A mostly solitary life

Malayan tapirs spend much of their lives alone, although individual home ranges can overlap. They move along pathways through the undergrowth and mark areas with urine, leaving scent cues for other tapirs.

Although they are often described as nocturnal, their activity is more flexible. They frequently forage around dusk and dawn and may rest during portions of the night, making them partly crepuscular as well.

High-pitched squeaks and whistles help tapirs communicate, particularly when individuals come together to breed.

Breeding generally occurs from April through June. After a gestation lasting around 390 to 395 days, a female usually gives birth to a single calf. Young tapirs weigh about 6.8 kilograms (15 lb) at birth and look dramatically different from adults.

Instead of the adult black-and-white coat, calves are covered in brown fur patterned with white stripes and spots. The markings help conceal them in the dappled light of the forest and gradually fade between four and seven months of age.

The power of the proboscis

One of the Malayan tapir’s most useful adaptations is its long, flexible proboscis.

Tapirs have relatively poor eyesight and rely heavily on their excellent senses of smell and hearing to navigate their surroundings. Their mobile noses help them investigate the forest and grasp vegetation while feeding.

Malayan tapirs are herbivores, eating tender shoots, leaves, and fruit from a wide variety of plants. More than 115 plant species have been documented in their diet. They may bend or break saplings to reach foliage and use their proboscis to pull vegetation toward their mouths.

They are also closely associated with water. Malayan tapirs regularly bathe and swim and are capable of climbing steep riverbanks and forest slopes.

Moving seeds through the rainforest

Eating fruit also connects Malayan tapirs to the reproduction of the forest itself.

Seeds that survive being eaten can travel with a tapir before being deposited elsewhere. Research on Malayan tapirs has found that they can effectively disperse small-seeded plants over long distances, potentially carrying seeds roughly a kilometer or more from where the fruit was eaten.

Their relationship with seeds is complex, however. Malayan tapirs may crush or digest larger seeds rather than dispersing them intact. This means they do not perform exactly the same ecological role as larger Southeast Asian herbivores such as elephants, or even as tapir species living in Central and South America.

Still, by browsing vegetation, eating fruit, moving seeds, and creating pathways through dense understory, Malayan tapirs influence the structure and regeneration of the forests they inhabit.

Protecting a disappearing forest giant

The Malayan tapir is classified as Endangered on the IUCN Red List, with fewer than 2,500 mature individuals estimated to remain in the wild.

Its greatest threat is habitat loss and fragmentation. Forests throughout its range have been cleared or divided by logging, agriculture, oil palm plantations, settlements, and infrastructure. Roads can be particularly dangerous as fragmented habitats force tapirs to move across developed landscapes.

Fragmentation also separates populations from one another, making it harder for individuals to move between suitable habitats and maintain healthy breeding populations.

Protecting remaining forests is therefore only part of the solution. Restoring degraded habitat and maintaining connected forest corridors can give Malayan tapirs room to forage, reproduce, and move across the landscapes they have inhabited for thousands of years.

Protecting those landscapes also protects the many plants and animals that share them. For an animal built to wander through forests, keeping those forests connected may be one of the most important steps toward ensuring the Malayan tapir continues shaping Southeast Asia’s rainforests for generations to come.
