Tarsiers are only protected by law in Malaysia and Indonesia. They are hunted by people for pets, but soon die as they require live food and are very susceptible to tapeworms. In addition, the destruction of their forest habitat is also reducing the population of the Western tarsiers.
Tarsiers display a variety of interesting behaviors. One unique behavior is the tiny animal’s ability to leap over 2 meters in distance and 1.5 meters in height. Tarsiers have this ability due to their extremely long hind leg structure as well as using the long tail for balance during the leap.
The tarsiers prefer to groom themselves, except during mating season. This is done using the third and fourth toe claws to scratch their bodies followed by fur licking. The animals clean their faces by rubbing it against tree branches.
They are monogamous and live in family units. This unit consists of the mated pair and offspring. After sexual maturity offspring remain in close proximately to their parents and are sexually mature at one year old. They give birth to one offspring with a gestation period of six months. The offspring are born precocial, with their eyes open and bodies covered with fur. After approximately 45 days, young are weaned as they can capture their own prey.
