How long do monkeys live? 🐒 Turns out we don't really know! Postdoc in Centre for Research in Animal Behaviour at UoExeter modelling primate lifespans. Also elephant social network analyst 🐘 running entirely on sugar and a love of African wildlife 🌍

Given all of the recent genAI discussion, I wish to repost this.

Follow up fact: based on the photos that I have seen alone, these monkeys spend their time exclusively bunched together peering down questioningly from trees 👀

Primate Profile #38: Brumback's Night Monkey
These nocturnal monkeys like sleeping in tree hollows during the day. At night, despite exceptional night vision, they stay close to sleeping sites on new moons when it's darkest and roam further under full moons.

Primate Profile #37: White-cheeked spider monkey
Found in the middle of the Amazon basin, these spider monkeys live in large fission-fusion groups of 20-30 members, with subgroups of 2-4. This likely reduces foraging competition while still providing predator protection.

Primate Profile #39: Arunachal macaque
There are some questions as to whether these macaques are a species in their own right or a subspecies of Assamese macaque. They inhabit India's Arunachal Pradesh region, on the border with Bhutan, at the foot of the Himalayas.

Primate Profile #40: Pileated Gibbon
"Pileated" means capped, referring to the black cap on the otherwise-pale-furred-female's head. The male is entirely black. They can swing at up to 35mph through the canopy; on the ground they keep their arms above their head to walk!

Primate Profile #36: Grays bald-faced Saki
Despite their rather un-aerodynamic appearance, these monkeys are very agile among the treetops, able to leap 9m between branches. With a body size of ~40cm, this is 20-25 times their own body length!

Primate Profile #35: Collared Titi
Titis are monogamous, with the adult male leading his family to feeding spots. They eat predominantly fruit, but if they pick up invertebrates they will eat them too. Lactating females eat the most inverts to get extra protein.

West Javan ebony langurs (Trachypithecus mauritius) are endemic to West Java. Infants are born golden orange and darken after about 3 months. Specialized salivary glands and sacculated stomachs break down their leafy, high-cellulose diet. Threatened by habitat loss and hunting. Listed as Vulnerable.
