While these darling Gremlin-like creatures — commonly known as lorises — may be the epitome of cuteness overload, they’re not necessarily the cuddly little critter they appear to be. Lorises are actually mildly poisonous animals capable of a toxic vampire-like bite that can deliver excruciating pain.

Slow Lorises have sebaceous tissue much like sweat pores on the inside of their elbows that secretes a toxin. When these cute little fur-balls feel threatened, they fold their arms above their heads to quickly take the toxin from their forearms into their mouth in preparation to bite.

They then deliver the poison with their powerful jaw muscles and disproportionately large, sharp, fang-like teeth. But it isn’t really the oversized canine-like teeth that deliver this toxin, rather, their harmlessly small teeth in the front lower jaw which slope forward that serve to conduct the saliva into the wound.

Widely recognized by their huge eyes encircled by dark patches and their short index fingers, they are tailless or short-tailed primates with soft gray or brown fur, found in the South and Southeast Asian rainforest and central Africa.

Lorises are arboreal creatures that prefer the tops of the trees. They are nocturnal animals, curling up to sleep by day. Their enhanced night vision is enabled by a specialized layer (the tapetum) in the retina of the eye that reflects light. Their eyes are fixed and cannot move, so they must swivel their heads around much like an owl.

These animals have an enhanced perception of smell and accompanying this is the extensive use of scent marking through their specialized glands. They have very sensitive hearing and ears they can move independently to capture sounds even better.

Unlike most primates, lorises don’t jump or leap through trees — they move with great deliberation through the trees and often hang by their feet, with their hands free to grasp food or branches. With their strong hands they clasp at the branches and cannot be removed without significant force. Specialized blood vessels allow them to grip onto things for hours.

Lorises are an endangered species, frequently poached from the wild as pets. They’re solitary creatures which make for a great challenge for care in captivity. Many are found in Asian markets with their canine teeth removed to reduce the effect of their bites, thus affecting their ability to feed for a proper diet. However, it’s not as much as the pet trade that threatens their survival as it is for their habitat destruction, and being killed for use in Asian medicines.

About Lorises
Lorises belong to the ancient primate suborder informally referred to as prosimians. Loris is the common name for the strepsirrhine primates of the subfamily Lorinae in the Lorisidae family. Loris is one genus in this subfamily and represents the slender lorises, while Nycticebus is the genus for the slow lorises.

The clade of Strepsirrhini is one of the two suborders of primates. One of their most distinguishing characteristics is their wet noses. Their moist nose is connected to the upper lip which is connected to the gum, limiting the facial expressions they can manage. Their snouts are generally elongated giving them a dog-like appearance. Strepsirrhines also have an unusual ability to enzymatically manufacture vitamin C.

They have a close, woolly fur which is usually grey or brown colored, darker on the top side. The eyes are large and face forward, and their ears are small and often partially hidden in the fur.

Strepsirrhines have a toothcomb — tightly clustered incisors and canine teeth — that’s used for grooming. The second toe of the hind legs has a fine claw used for grooming as well, while the big toe is widely separated from the others allowing a vise-like grip for locomotion. The thumbs are opposable and the index finger is short.

Their tails are short or are missing completely. They grow to a length of 7 to 16 inches (17 to 40 centimeters) and a weight of between 10 ounces to 4.5 pounds (0.3 and 2 kilos), depending on the species.

Some have slow deliberate movements, while others can move with some speed across branches. It was previously thought that all lorises moved slowly, but investigations using red light proved this to be wrong. Nonetheless, even the faster species freeze or move slowly if they hear or see a potential predator. This habit of remaining motionless while in danger is successful only because of the leafy environment of their jungle home, which helps to conceal their true position.

Most lorises are solitary creatures or live in small family groups.

Their main diet consists mostly of insects, but they also eat bird eggs and small vertebrates as well as fruits and sap.

Instead of an individual cycle, strepsirrhines have a breeding season, with a gestation period of 4 to 6 months, birthing up to 2 young. The babies often clasp themselves to their mother’s belly or wait in nests while the mother goes to search for food. After 3 to 9 months — depending upon the species — they’re weaned and are fully mature within 10 to 18 months. Life expectancy of lorises can be to up to 20 years in the wild.

Slender Loris
Slender lorises (Loris tardigradus) are 2 species of loris native to India and the rainforests of Sri Lanka, which include:

The Gray Slender Loris, which is about 8 to10 inches (20 to 25 centimeters) long and has long, slender limbs, small hands, a rounded head, and a pointed muzzle. They feed mostly on insects (predominantly ants) and are solitary. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical moist lowland forests, and are threatened by habitat loss.

The Red Slender Loris favors lowland rainforests tropical rainforests and inter-monsoon forests of the south western wet-zone of Sri Lanka. Masmullah Proposed Forest Reserve harbors one of few remaining Red Slender Loris populations, and is considered a biodiversity hotspot. They are #22 of the 100 EDGE animal species worldwide considered the most Evolutionarily Distinct and Globally Endangered.

This small, slender primate is distinguished with large forward facing eyes used for precise depth perception, long slender limbs, a well developed index finger, the absence of a tail, and large prominent ears, which are thin, rounded and hairless at the edges.

The soft dense fur is reddish-brown on the back and the underside is whitish-grey with a sprinkling of silver hair, and a dark face mask with central pale stripe, much like the slow loris. Their average body length is 7 to 10 inches (17 to 26 centimeters), with an average weight of a mere 3 to13 ounces (85 to 350 grams). They have a 4-way grip on each foot — the big toe opposes the other 4 toes for a pincer-like grip on branches and food.

The Red Slender Loris differs from the Gray Slender Loris in its frequent use of rapid arboreal locomotion. It forms small social groups, containing adults of both sexes and young animals. This species is among the most social of the nocturnal primates. During daylight hours the animals sleep in groups in branch tangles, or curled up on a branch with their heads between their legs. They make nests out of leaves or find hollows of trees or a similar secure place to live in.

The groups also undertake mutual grooming and play at wrestling. The adults typically hunt separately during the night. They’re mostly insectivorous but also eat bird eggs, berries, leaves, buds and occasionally invertebrates as well as geckos and lizards. To maximize protein and nutrient intake they consume every part of their prey — the scales, bones, and all.

Females are dominant, reaching their sexual maturity at 10 months. They’re receptive to the males twice a year, mating while hanging upside down from branches. Those in captivity will not breed if no suitable branch is available. The gestation period is 166 to169 days after which the female will birth 1 to 2 young which feed from her for 6 to 7 months. The lifespan of this species is believed to be around 15 to18 years in the wild.

This slender loris is an endangered species. Habitat destruction is a major threat, but they’re also widely trapped and killed for use in supposed remedies for eye diseases and for use as laboratory animals. Other threats include electrocution on live wires, road accidents, and the pet trade.

Slow Loris
Slow lorises are 3 species of loris, classified as the genus Nycticebus. These slow moving strepsirrhine primates range from Borneo and the southern Philippines in Southeast Asia, through Bangladesh, Vietnam, Southern China (Yunnan area) and Thailand.

Adult slow lorises vary in size from 8 to 15 inches (21 to 38 centimeters), weighing up to 4.5 pounds (2 kilos) — much of it located in their bottom! — and generally more strongly built than the slender loris. The short, thick fur can have a variety of color, mostly grey-reddish often with whitish undertones, and the tail is a mere stump. They have well developed thumbs which they use to grasp and hold fast to branches, and a very flexible back. The eyes are large and point forward and the ears are small and nearly hidden in the fur.

They make slow, deliberate movements and have a powerful grasp that makes them very difficult to remove from branches. They live as solitaries or in small family groups, and mark their territory with urine.

Slow lorises can produce a toxin created by glands on the insides of their elbows which they mix with their saliva and use as protection against enemies by licking or sucking it into their mouths and delivering it when they bite. Mothers will lick this toxin onto their offspring before leaving them to search for food. The toxin is not known to be fatal to humans, but causes a painful swelling.

They are happenstance carnivores, typically eating insects, bird eggs and small vertebrates. With their slow quiet movements, they creep to their prey in order to catch it with a lightning-quick snatch. They also eat fruits, but rarely.

After about a 190-day gestation, the female births one (or rarely two) young. The newborn clasps itself to the belly of the mother or the father. When it’s older it will be “parked” on a branch while its parent searches for food, and weaned after approximately 9 months. The life expectancy of the slow loris is up to 14 years.

The Sunda Loris (Nycticebus coucang) is a slow loris with large eyes that point forward, and ears that are small and nearly hidden in the fur. Its tail is a mere stump, but it has well developed thumbs. They are a nocturnal and arboreal animal, sleeping their days curled up in a tree top and prowling the night devouring small animals and fruit.

The Pygmy Slow Loris (Nycticebus pygmaeus) is a rare species of loris found in the tropical dry forests of Vietnam, Laos, China, and parts of Cambodia. About 72,000 of the creatures live in the wild, and approximately 200 are in captivity.

This primate is a nocturnal animal and will eat fruit, insects, small mammals, slugs and snails. It can catch prey by licking the toxin that’s released from the inside of its elbows and delivering it via its teeth.

They are arboreal, crawling on branches, unnoticed as they quietly move through the thick leaves of the subtropics, and live together in small groups.

Adults can grow to around 7 to 8.5 inches (18 to 21 centimeters) long, weigh about 1 pound (450 grams), and have virtually no tail.

This species mates once every 12 to 18 months and will have 1 to 2 offspring after an average gestation period of 190 days. For the first few days, the young loris clings to belly of its mother. After 9 months the baby will be weaned and at that point the females will be sexually mature while males reach maturity between 17 to 20 months.

The pygmy slow loris was nearly wiped out during extensive burning, clearing and defoliating of forests in Vietnam during the Vietnam war.

Traditional Japanese medicine has many uses for the Bengal Slow Loris, and it has been traded close to extinction. Countries such as Britain have now enacted bans on the trade of slow lorises or products derived from them.
