The dramatic landscapes of Cat Ba Island are characterised by limestone boulders, coral reefs, mangrove forests, lagoons, beaches, and willow swamp forests. Its variety of natural ecosystems explains why the island is home to over 1,500 species of flora and fauna, some of which do not exist anywhere else. (Photo: VNA)
The Cat Ba langurs are on the brink of extinction, with only some 70 individuals remaining. They are restricted to less than 20 sq km of moist tropical forest on limestone karst hills in Cat Ba National Park, about 135 metres above sea level. (Photo: VNA)
The Cat Ba langur, or Golden-headed langur, is one of the world’s most critically-endangered primates. In 2006, there were only an estimated 64 surviving individuals on Cat Ba Island’s limestone hills. (Photo: VNA)

Cat Ba langurs have long, slender bodies, long limbs, and extremely long tails of 82-89 cm. The tail is not for grasping, but helps the langurs keep their balance while on the move. Their body is covered with thick dark brown-to-black hair, which is longer at the back and gives them the appearance of wearing a vest. (Photo: VNA)
Cat Ba Langur - Endangered primate species
The Cat Ba langurs, or Golden-headed langurs, are found only on Cat Ba Island in the Gulf of Tonkin, off the coast of northern Vietnam. They are one of the world’s most critically-endangered primates.
