Three new species of slow loris have been discovered in Borneo. They had previously been grouped with other species, but research has found them to be separate species, and thus much more vulnerable to extinction.

A loris is a type of venomous primate that has two tongues. With their large eyes and teddybear-like appearance, they are often a target of the illegal international pet trade.

“Four separate species are harder to protect than one, since each species needs to maintain its population numbers and have sufficient forest habitat,” said lead author Rachel Munds, MU doctoral student in anthropology in the College of Arts and Science. “Unfortunately, in addition to habitat loss to deforestation, there is a booming black market demand for the animals. They are sold as pets, used as props for tourist photos or dismembered for use in traditional Asian medicines.”


Because they aren’t domesticated they are afforded some legal protection under the Convention on International Trade in Endangered Species. As the researchers note, keeping the intelligent and social animals as pets is cruel and the animals often do very poorly in captivity. And the animals often have their teeth removed in very inhumane ways before being sold.

“Even zoos have difficulty meeting their nutritional needs for certain insects, tree gums and nectars,” said Munds. “Zoos rarely succeed in breeding them. Nearly all the primates in the pet trade are taken from the wild, breaking the bonds of the lorises’ complex and poorly understood social structures. The teeth they use for their venomous bite are then torn out. Many of them die in the squalid conditions of pet markets. Once in the home, pet keepers don’t provide the primates with the social, nutritional and habitat requirements they need to live comfortably. Pet keepers also want to play with the nocturnal animals during the day, disrupting their sleep patterns.”

“The newly identified species hail from the Indonesian island of Borneo. Munds and her colleagues observed that the original single species contained animals with significantly different body sizes, fur thickness, habitats and facial markings. Museum specimens, photographs and live animals helped primatologists parse out four species from the original one. Now instead of one animal listed as vulnerable by the International Union for the Conservation of Nature, there may be four endangered or threatened species. This potential change in conservation status may serve to draw attention the plight of the primates and increase legal protections.”

“YouTube videos of lorises being tickled, holding umbrellas or eating with forks have become wildly popular,” said Anna Nekaris, study co-author, primatology professor at Oxford Brookes University and MU graduate. “CNN recently promoted loris videos as ‘feel good’ entertainment. In truth, the lorises gripping forks or umbrellas were simply desperate to hold something. The arboreal animals are adapted to spending their lives in trees constantly clutching branches. Pet keepers rarely provide enough climbing structures for them.”

“The pet trade isn’t the only threat to loris survival. The animals also are used in Asian traditional medicines. The methods used to extract the medicines can be exceedingly violent, according to Nekaris, who also is director of the slow loris advocacy organization, Little Fireface Project. For example, in order to obtain tears of the big-eyed lorises, skewers are inserted into the animals’ anuses and run through their bodies until they exit the mouth. The still-living animals are then roasted over a smoky fire and the tears that stream from their eyes are collected and used to supposedly treat eye diseases in humans.”

A video about the illegal trade in slow lorises can be viewed here.

“Taxonomy of the Bornean Slow Loris, with New Species Nycticebus Kayan,” was published in the American Journal of Primatology. The paper described the physiological and habitat differences that justified dividing the three new species of slow loris (N. bancanus, N. borneanus and N. kayan) from the original species of slow loris N. menagensis. Susan Ford of Southern Illinois University also was co-author.

    If i were, or ever decide to become a serial killer, i will find & make my victims to be the  illegal poachers & the captors, and the BUYERS of these precious & vital part of our planet. then, I would return & release them in their native environment. Further more, I would buy up all the remaining habitat and seal it from any encroachment from all humans. Any trespasser would be killed & left as food to any species desiring to eat.  I will do these things ! If I CAN …

    the world of animal cruelty is appalling and
    I could only hope that more people become aware and work to stop this inhumane atrocity.
