"Rare Primate Playtime Captured on Camera in Treetop Haven"

The cao-vit gibbon, the world's second rarest primate with only 135 individuals left in the wild, has been captured on film in Vietnam. This critically endangered species, known for its distinctive sexual dimorphism and territorial songs, faces threats from habitat loss and degradation. Conservation efforts by Fauna & Flora International and agreements between Vietnam and China aim to protect and increase the population of these gibbons. The world's rarest primate is the Hainan gibbon, with only 28 individuals remaining.
