Meet the Loris :)

Loris is a small nocturnal and arboreal animal that lives in India through Burma, Srilanka, Thailand, and peninsular Malaysia, across into Vietnam, Cambodia, Laos and into the islands of Indonesia and the Philippines.

They live in forests and prefer thick, thorny vegetation wherein they can easily escape predators.They prefer thick, thorny vegetation wherein they can easily escape predators and find the large assortment of insects that is the mainstay of their diet.

They represent more than one species. In-fact there are now five species that are formally recognized by scientists and probably more will be identified soon. Since no one is sure how many species there really are, nor how big each species' population and natural range is, the threat that they are facing is also unclear. Additionally, no one knows the scale of the international loris trade either, although it is known that these animals are sold as pets throughout the Middle East, Europe, China and the US.

They certainly make ideal pets because they are small, quiet, and easy to keep in captivity. Slow lorises vary in color from grey to white depending on their species. Additionally, they are certainly cute: their face is round, with large eyes and small ears. They have plump bodies with short limbs, strong grasping hands and feet, and opposite thumbs. The slow loris's fur coat is dense, woolly and soft, and they have dark rings around their eyes and a dark stripe running along their back. Its short tail is entirely concealed by fur.

"The pet shops advertise them, and they're very popular to Japanese ladies," said Masayuki Sakamoto from the Japan Wildlife Conservation Society. A slow loris costs between $1500-4500 in Japan.

The slender loris is a small, nocturnal primate found only in the tropical rain forests of Southern India and Sri Lanka. Loris Tardigradus malabaricus is a subspecies of the slender loris which is only found in India. The greatest concentrations of these slender lorises are found in the southeastern Ghats of India.

The slender loris is about the size of a chipmunk, with long, pencil-thin arms and legs. It is between 6-10 in. (15-25cm) long and has a small, vestigial tail. It weighs about 10.5-12 oz. (275-348g). The slender loris' round head is dominated by two large, closely set, saucer-like brown eyes. They flank a long nose which ends in a heart-shaped knob. The eyes are surrounded by dark-brown to black circles of fur, while the bridge of the nose is white. It has a small, narrow lower jaw. The ears are large and round. Its coat is light red-brown or gray-brown on its back and dirty white on its chest and belly. The fur on its forearms, hands and feet is short.

The slender loris has small finger nails on its digits. The second digit on the hand and foot are very short. They move on the same plane as the thumb, which helps them grasp branches and twigs.The slender loris spends most of its life in trees. Its movements are slow and precise. They like to travel along the top of branches. For the most part they hunt by themselves or in pairs at night, although they will come together and share a food supply. They live alone or with a mate and an infant. They will sleep with up to seven other lorises in a hollow tree or sitting up in the angles of branches. They are very social at dusk and dawn, playing, wrestling and grooming each other.

The slender loris is for the most part insectivorous. This means they eat insects, but they will also eat slugs, young leaves, flowers, shoots, and occasionally eggs and nestlings. They can stretch and twist their long arms and legs through the branches without alerting their prey. The slender loris eats a lot of noxious and bad smelling insects. They particularly like the acacia ant whose bite can numb a human arm. They also like toxic beetles and roaches. The slender loris will engage in urine washing, or rubbing urine over their hands, feet and face. This is thought to soothe or defend against the sting of these toxic insects.

Mating occurs twice a year; in April-May and October-November. Gestation is 166-169 days, after which one, and occasionally two infants are born. During the first few weeks mothers carry their infants constantly. The infant will grasp its mother around the waist with both its front and hind legs. After a few weeks the mother "parks" the infant on a branch at night while she forages. The babies move around carefully at first but by two months they are maneuvering around quite well. More mature lorises who sleep in the same tree may visit them at night to play and eat with them. Females will reach sexual maturity in 10 months and 18 months for males. The slender loris has a life span of 12 to 15 years.

Even though slow lorises are highly esteemed pets, the pet trade does not appear to treat the small furry animals very well. For example, vendors will often pull out an animal's teeth so they can claim it is a baby to interested customers. Babies are taken away from their parents before they can groom themselves so their fur becomes matted with feces and oils, and further, most babies (30-90%) end up dying in transit to pet shops. Additionally, animals often get bloody cuts on their sensitive hands and feet when they are removed from wire cages, due to their special network of blood vessels.

It is not clear how many slender lorises survive in the wild. Because of their small size and nocturnal habits, it has been difficult to do an accurate count. Until recently not much attention has been paid to the plight of the slender loris, but new interest has been shown in their species and studies are under way. The Indian government has laws protecting the slender loris, but its effect is difficult to gauge.

  1. Buying slow lorises is actually illegal, worldwide. They are NOT easy to keep, as they have a very specialized diet. Mortality is high in captivity.
