Kayan River slow loris
The Kayan River slow loris is a small, nocturnal primate that lives in the highlands of northern and central Borneo. It is the only primate known to have a toxic bite, which it uses to defend itself. It is classed as Vulnerable because its forest home is being lost.1

怎麼認出牠
- High contrast between its black and white facial markings1
- The stripe between its eyes is sometimes bulb-shaped rather than rectangular1
- The ears are always covered in hair1
- Its fur is generally longer and fluffier than that of the Bornean slow loris1
常被誤認為: It is often confused with the Bornean slow loris (N. menagensis). The Kayan River slow loris has more contrast in its facial markings, hairy ears instead of naked ears, and longer, fluffier fur.1
毒液力量
咬的時候,毒液會從毒牙或牙齒出來。
牠的毒液有什麼作用?
It has a toxic bite, which is unusual among primates. A pungent, clear, oily toxin is made in a gland on the inside of its elbow. The animal licks this gland, and the secretion mixes with its saliva to become active. The toxin is also rubbed onto its fur as protection for infants.1
牠對人有多危險?
對人的危險: 疼痛可能會非常痛,但幾乎從來不會很嚴重。牠害怕時會做什麼?
When threatened, it wipes the toxin from its elbow gland onto its toothcomb, and it may bite the attacker. Slow lorises can be slow to let go of a bite, which helps deliver more toxin.1
注意安全
- 絕對不要碰、抓或捉弄野生動物,就算是很小的動物,就算牠看起來在睡覺或已經死了也一樣。
- 給牠空間。如果遇到了,保持冷靜,慢慢往後退,讓牠自己離開。
- 如果被牠咬了:保持冷靜,保持不動,打緊急電話(112、000、911)或趕快去醫院。記住牠的樣子,有照片會很有幫助。
牠不是想來抓你。牠用毒液來捕捉食物或保護自己,而且牠更想躲起來。 更多安全知識

小知識
It is one of the few primates known to have a toxic bite, and this is a unique feature among primates.1
Its face mask may help it recognise other lorises of its own kind, and it may also make its eyes look bigger than they really are, which can deter predators.1
It has a toothcomb, a set of specialised lower front teeth that it uses for grooming.1
Its population is estimated to have fallen by more than 30% over about 21 to 24 years.1
破解迷思
迷思: The Kayan River slow loris was always known as a separate species.
真相: Until 2013 its museum specimens were identified as the Bornean slow loris. A study of facial markings then showed it was a distinct species.1
