Brown Spider Monkey

Critically Endangered



The brown spider monkeys are critically endangered primates and in the world, they lie in one of the top 25 most endangered primates. Almost 3,000 of these primates are thought to be left in wild. One of the biggest causes for their endangerment is the demolishing of forest habitats for cattle ranching, illegal mining, and oil palm.


The size of brown spider monkeys is from 35 to 70 centimetres


The weight of the Ateles hybridus is about 7.5 to 9kg. Their life span is 10-27 years. But some researches show that their life span is 22 years in the wild.


Colombia and Venezuala


Brown spider monkeys have endeavoured to northern Colombia and northwestern Venezuela. They are woodsy species that go for the canopies of big trees.

Primary forests are the foremost suited for brown spider monkeys to occupy because they prefer more crowded canopies and fruits instead of discontinuous trees This species does well at heights anyplace from 20 – 700 metres.


The appearance of Ateles hybridus is comparative to other species of creepy-crawly monkeys and, as their common name demonstrates, brown spider monkeys have uncommonly long, slender limbs. Their forelimbs are longer than their hind limbs and their interfemoral file is around 105.

They moreover have a long, narrow, prehensile tail, which acts nearly like a fifth limb. These highlights empower them to be profoundly suspensory and permit them to effortlessly scrounge and travel within the giant canopy.

Their coloration ranges from light brown to dull on the upperparts counting the head. The inward side of the legs, arms, and tail is a lighter, more buff colour. Another recognizing characteristic of this species is the white triangular brow fix but not all people have this obvious include. A few individuals have pale blue eyes, but more often than not they are light brown.
