About the second rarest primate in the world, the gray gibbon (Nomakos Natosos) was recorded in a Vietnamese jungle, she says IFLScience. The video also shows three specimens – two adults and a younger individual – playing in the canopy. The smaller individual eventually stumbles through the trees. This species exhibits sexual dimorphism, with males having black fur and females having brown or yellow fur.
The grey-headed gibbon is listed as Critically Endangered on the International Union for Conservation Red List.
The sharp decline in population is caused by habitat destruction, which was caused by the advent of agriculture and logging.
This species was thought to be extinct until 2002, when a small population was discovered near the Chinese border. Recently, specialists have done a lot to protect animals and their habitats, and in 2012, China and Vietnam signed an agreement on the protection of species.
By the way, the rarest primate in the world is also a gibbon, the hagnani gibbon (Nomascus hainanus). Only 28 individuals of this species remain in the wild in China's Hegnan Archipelago.
