Many species are endemic and rare, the most significant being the globally important Golden headed langur (Trachypithecus poliocephalus), restricted in range to Cat Ba Island and found nowhere else in the world.

The Hawksbill turtle (Eretmochelys imbricata) which is found in the Cat Ba region is listed in the Red Data book, the seahorse (Hippocampus spp.) is also rare and threatened. Mangroves and segrasses in Cat Ba are as a nursery ground for the life in the bay, and protective buffers for local people from storm surges and typhoon driven from climate change and sea level rise.
