Fun Fact(s):
‘Loris’ may derive from Dutch ‘Loeres’ meaning ‘sluggish’ or ‘Loeris’ meaning ‘clown’ maybe due to facial appearance.
Have extremely strong fingers/toes, being able to maintain grip for hours.
1 of very few venomous mammals-1 of only 8 venomous primates-others being the other 7 slow loris species. Toxin obtained by licking sexual gland on arm w/ secretion activated by mixing w/ saliva. Venomous bite deterrent to predators & moms also apply toxin to infant’s fur when grooming for protection. Bites often cause anaphylactic shock & occasionally, death. Protein in venom similar to allergenic protein on cats.
Both sexes, but especially males, fight to death by using venom, often licking brachial glands.
Despite viral videos/photos w/ these animals as pets, they make terrible pets. 1st, they’re nocturnal & don’t like bright light. 2nd, they’re almost always taken from wild, w/ many dying in transit. Traffickers usually pull teeth out (due to venomous bite). Despite viral video w/ loris being tickled raising arms above head looking happy, that loris wasn’t happy-it was attempting to defend itself by accessing venomous gland in elbow. In fact, International Animal Rescue launched Tickling is Torture campaign in 2015 to raise awareness. Often animals destined for pet trade can’t be released back into wild due to lack of teeth.
