Slow lorises are part of the illegal wildlife trade in Asia. He has the fewest body measurements of the group studied by Dr. Nekaris because he is so vicious to handlers. Despite such a variety of options to choose from, they tend to spend approximately 90% of their feeding time eating nectars. More Science. They are similar to other lorises, as they are nocturnal and arboreal, using vines and lianas to climb. But other unidentified compounds seem to lend additional toxicity and cause extreme pain. Lorises typically reserve their venomous bites for attacks on other lorises, according to a study published in October. Additionally, zoo and rescue facility staff report that one of the most frequent causes of death for slow lorises is bites from other slow lorises. We examine four hypotheses for the function of slow loris venom. Illegal pet traders in Indonesia told Dr. Nekaris that they remove the animals’ teeth not to protect future owners, but to prevent slow lorises from harming each other and ruining their price.

But other unidentified compounds seem to lend additional toxicity and cause extreme pain. The findings represent “a really cool addition to our knowledge,” said Kevin Arbuckle, an evolutionary biologist at Swansea University, who was not involved in the new study.

When it was time for Maaf to disperse, he was bitten by another loris and tried to come back home, only to be rejected by his father, Fernando, who threw him out of a tree. But anecdotal evidence has also hinted for years that slow lorises may use their venom against their own. The least evidence is found for the hypothesis that loris venom evolved to kill prey. The paper also lends unique insight into how individuals of the same species may use venom on one another to compete for limited resources such as mates or territory — something that few studies have examined, said Ronald Jenner, a venom specialist at the Natural History Museum in London, who also was not involved in the research. It is still not clear for what reason the slow loris is venomous; The slow loris is endangered due to both habitat loss and hunting for illegal pet and traditional medicine trades. They recaptured the animals every few months for health checks. Fernando, a killer slow loris.

The Little Fireface Project presents a glimpse of our work on slow loris venom! Males suffered more frequent bites than females, as did young animals dispersing from their parents’ territories. While necrotic wounds were a regular occurrence, predation was not; since 2012, the researchers have lost just one Javan slow loris to a predator, which was a feral dog. An adult male slow loris named Azka (who happens to be Alomah’s father) baring its teeth, which show the toothcomb, or front lower teeth, which allow the venom to be injected. With their bright saucer eyes, button noses and plump, fuzzy bodies, slow lorises — a group of small, nocturnal Asian primates — resemble adorable, living stuffed animals. Strangely, to produce the venom, the melon-sized primates raise their arms above their head and quickly lick venomous oil-secreting glands located on their upper arms. Nekaris and her colleagues concluded that slow lorises are remarkably territorial and that they frequently use their venom to settle disputes. Poachers interviewed by her also complained of sometimes capturing “ugly” slow lorises with extensive scarring or gaping wounds that they had to let go because no pet buyer would want them. It moves very slowly, as its name suggests, across vines on trees instead of jumping between branches. They are the largest of the Indonesian slow lo⦠“It causes necrosis, so animals may lose an eye, a scalp or half their face.”. “This very rare, weird behavior is happening in one of our closest primate relatives,” said Anna Nekaris, a primate conservationist at Oxford Brookes University and lead author of the findings, published Monday in Current Biology.

Slow Loris are the primate that belongs to a sub-family known as Loraine. Azka’s daughter Hesketh, about 6 months old showing the venom posture. Additionally, slow loris bites to other slow lorises are a major cause of death of captive animals. They recaptured the animals every few months for health checks. Over an eight-year span, the researchers spent more than 7,000 hours monitoring their study subjects in a 2-square mile patch of forest. (A) Examples of head wounds resulting from venomous bites: dispersing male (above), dispersing female (middle), resident male after a territorial fight when he maintained his territory (below). Stranger still, the slow lorsisesâ venom isnât in their saliva, but is produced when the animals raise their arms above their heads (like in that cute video) and âquickly lick venomous-oil secreting glands located on ⦠Before this study, many still debated the primary purpose of slow loris venom. Venom is activated by combining the oil from the brachial arm gland with saliva, and can cause death in small mammals and anaphylactic shock and death in humans. It mixes the secretion from a gland on the underside of its arm with its saliva to produce a toxin.

Dr. Nekaris and her colleagues concluded that slow lorises are remarkably territorial, and that they frequently use their venom to settle disputes. It isnât injected into the body via fangs as happens in a venomous snake bite, however, so the use of the term "venom" is somewhat controversial. “The result of their bite is really, really horrendous,” Nekaris said. Over an eight-year span, the researchers spent more than 7,000 hours monitoring their study subjects in a two-square mile patch of forest. Javan slow lorises are territorial and use venom for intraspecific competition. Venomous Slow Loris May Have Evolved To Mimic Cobras. Like other types of slow lorises, Javan slow lorises form long-term mating pairs that occupy small territories containing one or several gum-producing trees.
