This is a list of the mammal species recorded in Hong Kong. There are 14 mammal species in Hong Kong, of which 0 are critically endangered, 1 is endangered, 0 are vulnerable, and 1 is near-threatened.[1]

The following tags are used to highlight each species' conservation status as assessed by the IUCN:

EX Extinct No reasonable doubt that the last individual has died.
EW Extinct in the wild Known only to survive in captivity or as a naturalized populations well outside its previous range.
CR Critically Endangered The species is in imminent risk of extinction in the wild.
EN Endangered The species is facing an extremely high risk of extinction in the wild.
VU Vulnerable The species is facing a high risk of extinction in the wild.
NT Near Threatened The species does not meet any of the criteria that would categorise it as risking extinction but it is likely to do so in the future.
LC Least Concern There are no current identifiable risks to the species.
DD Data Deficient There is inadequate information to make an assessment of the risks to this species.

Some species were assessed using an earlier set of criteria. Species assessed using this system have the following instead of Near Threatened and Least Concern categories:

LR/cd Lower Risk/conservation dependent Species which were the focus of conservation programmes and may have moved into a higher risk category if that programme was discontinued.
LR/nt Lower Risk/near threatened Species which are close to being classified as Vulnerable but are not the subject of conservation programmes.
LR/lc Lower Risk/least concern Species for which there are no identifiable risks.

Subclass: Theria

Infraclass: Eutheria

Order: Artiodactyla (Herbivore)

The order Artiodactyla in Hong Kong are mainly herbivore which feed only on plant material, except wildboar. There are three types of herbivores (includes native and feral) in recent Hong Kong.

Indian Muntjac

Order: Carnivora (carnivores)

Leopard Cat

The carnivores include over 260 species, the majority of which eat meat as their primary dietary item. Carnivores have a characteristic skull shape and dentition.

Otter

Order: Cetacea (whales)

Finless Porpoise

The order Cetacea includes whales, dolphins and porpoises. They are the mammals most fully adapted to aquatic life with a spindle-shaped nearly hairless body, protected by a thick layer of blubber, and forelimbs and tail modified to provide propulsion underwater.Only the Indo-Pacific humpback dolphin (Chinese white dolphin) and finless porpoise live in Hong Kong waters permanently,whilst the others are passers-by.

Chinese white dolphin

Order: Chiroptera (bats)

Common Noctule

The bats' most distinguishing feature is that their forelimbs are developed as wings, making them the only mammals in the world naturally capable of flight. Bat species account for about 50% of all mammals.

Order: Pholidota (pangolins)

The order Philodota comprises the eight species of pangolin. Pangolins are anteaters and have the powerful claws, elongated snout and long tongue seen in the other unrelated anteater species.

Order: Primates

Rhesus Macaque

The order Primates contains all the species commonly related to the lemurs, monkeys, and apes, with the latter category including humans. It is divided informally into three main groupings: prosimians, monkeys of the New World, and monkeys and apes of the Old World.

Order: Rodentia (mice, squirrel, etc)

Most rodents are small.It have two incisors in the upper as well as in the lower jaw which grow continuously and must be kept worn down by gnawing.Rodents are important in many ecosystems because they reproduce rapidly, and can function as food sources for predators, mechanisms for seed dispersal, and as disease vectors.

Order: Sirenia (manatees and dugongs)

Dugong(extine in Hong Kong)

Sirenia is an order of fully aquatic, herbivorous mammals that inhabit rivers, estuaries, coastal marine waters, swamps, and marine wetlands. All four species are endangered.

Order: Soricomorpha (shrews, moles, and soledons)

The "shrew-forms" are insectivorous mammals. The shrews and soledons closely resemble mice while the moles are stout bodied burrowers.

Notes

  1. ^ This list is derived from the IUCN Red List which lists species of mammals and includes those mammals that have recently been classified as extinct (since 1500 AD). The taxonomy and naming of the individual species is based on those used in existing Wikipedia articles as of 21 May 2007 and supplemented by the common names and taxonomy from the IUCN, Smithsonian Institute, or University of Michigan where no Wikipedia article was available.
