    Most notably, Cat Ba is the exclusive global habitat of the Cat Ba Langur (Trachypithecus poliocephalus). This critically endangered endemic primate faces severe threats from poaching and habitat fragmentation, with a remaining population of approximately 70 individuals.

Possessing exceptional climbing agility, they typically travel in small herds and represent a precious species requiring strict protection.
