Tapirs are large browsing mammals, roughly pig-like in shape, with short, prehensile trunks. They inhabit jungle and forest regions of South America, Central America, and Southeast Asia. All four species of tapir are classified as endangered or vulnerable. Their closest relatives are the other odd-toed ungulates, horses and rhinoceroses.
Species There are four tapir species: Hybrids Hybrid tapirs from the Baird's Tapir and the Brazilian Tapir were bred at the San Francisco Zoo around 1968 and produced a second generation around 1970. General appearance Size varies between species, but most tapirs are about 2 meters (7 ft) long, stand about a meter (3 ft) high at the shoulder, and weigh between 150 and 300 kg (330 to 700 lb). Coats are short and range in color from reddish-brown to grey to nearly black, with the notable exceptions of the Malayan Tapir, which has a white saddle-shaped marking on its back, and the Mountain Tapir, which has longer, wooly fur. All tapirs have oval, white-tipped ears, rounded, protruding rear ends with stubby tails, and splayed, hoofed toes, with four toes on the front feet and three on the hind feet, which help them walk on muddy and soft ground. Baby tapirs of all types have striped-and-spotted coats for camouflage, and while they appear at first glance to be alike, there are some differences among the patterns of different species. Females have a single pair of mammary glands. The penis of the male tapir is very long when erect. Physiology
Natural history The tapir family is old by mammalian standards. The earliest fossil tapir dates to the early Oligocene, and Eocene rocks from as early as 55 million years ago contain a wide range of tapir-like animals, and they have changed little since.* These ungulates could be found world-wide. Perissodactyls, including tapiroids, became the predominant large terrestrial browsers through the Oligocene, and many members of the group survived until the late Pleistocene. It is believed that Asian and American tapirs diverged around 20 to 30 million years ago, and that tapir varieties moved from North America to Central and South America around 3 million years ago. Lifecycle Young tapirs reach sexual maturity between three and five years of age, with females maturing earlier and coming into oestrus every two or three months. Under good conditions, a healthy female tapir can reproduce every two years; a single youngster is born after a gestation of about 13 months. The natural lifespan of a tapir is approximately 25 to 30 years, both in the wild and in zoos. Little is known for sure about tapirs’ mating patterns in the wild: there is some evidence that mature tapirs mate with the same partner for life, but pairs spend little or no time together aside from sexual activity. Apart from mothers and their young offspring, tapirs lead almost exclusively solitary lives. Behavior
Habitat, predation, and vulnerability Adult tapirs are large enough that they have few natural predators, and the thick skin on the backs of their necks helps to protect them from threats such as jaguars, crocodiles, anacondas, and tigers. The creatures are also able to run fairly quickly, considering their size and cumbersome appearance, finding shelter in the thick undergrowth of the forest or in water. However, tapirs have no reliable defense against humans, by far the greatest threat to their survival. Hunting for meat and hides has substantially reduced their numbers and, more recently, massive habitat loss has resulted in the conservation watch-listing of all four species: both the Brazilian Tapir and the Malayan Tapir are classified as vulnerable; and the Baird’s Tapir and the Mountain Tapir are endangered. Tapirs tend to prefer old growth forests and the food sources that can be found in them, making the preservation of primary woodlands a top priority for tapir conservationists. Genetics
Attacks on humans Tapirs are generally shy, but when they are scared they can defend themselves with their very powerful jaws. In 1998, a zookeeper in Oklahoma City was mauled and had an arm severed by a tapir bite, after she attempted to feed the attacking tapir's young. In 2006, a 46-year-old man who was lost in the Costa Rican jungle was found by a search party with a "nasty bite" from a wild tapir. However, such examples are rare; for the most part, tapirs are likely to avoid confrontation in favor of running from predators, hiding, or, if possible, submerging themselves in nearby water until a threat is gone.
