List of mammals of Papua New Guinea explained

This is a list of the mammal species recorded in Papua New Guinea. There are 244 mammal species in Papua New Guinea, of which seven are critically endangered, twelve are endangered and forty are vulnerable.[1]

Abbreviations

The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature:

EX ExtinctNo reasonable doubt that the last individual has died.
EW Extinct in the wildKnown only to survive in captivity or as a naturalized populations well outside its previous range.
CR Critically endangeredThe species is in imminent risk of extinction in the wild.
EN EndangeredThe species is facing an extremely high risk of extinction in the wild.
VU VulnerableThe species is facing a high risk of extinction in the wild.
NT Near threatenedThe 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 concernThere are no current identifiable risks to the species.
DD Data deficientThere 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: Sirenia (manatees and dugongs)

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: Rodentia (rodents)

Rodents make up the largest order of mammals, with over 40% of mammalian species. They have two incisors in the upper and lower jaw which grow continually and must be kept short by gnawing.

Order: Chiroptera (bats)

The bats' most distinguishing feature is that their forelimbs are developed as wings, making them the only mammals capable of flight. Bat species account for about 20% of all mammals.

Order: Cetacea (whales)

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.

Infraclass: Metatheria

Order: Dasyuromorphia (marsupial carnivores)

The order Dasyuromorphia comprises most of the carnivorous marsupials, including quolls, dunnarts, the numbat, the Tasmanian devil, and the recently extinct thylacine.

Order: Peramelemorphia (bandicoots and bilbies)

Peramelemorphia includes the bandicoots and bilbies: it equates approximately to the mainstream of marsupial omnivores. All members of the order are endemic to the twin land masses of Australia-New Guinea and most have the characteristic bandicoot shape: a plump, arch-backed body with a long, delicately tapering snout, very large upright ears, relatively long, thin legs, and a thin tail.

Order: Diprotodontia (kangaroos, wallabies, wombats and allies)

Diprotodontia is a large order of about 120 marsupial mammals including the kangaroos, wallabies, possums, koala, wombats, and many others. They are restricted to Australasia.

Subclass: Protheria

Order: Monotremata (monotremes)

Monotremes are mammals that lay eggs instead of giving birth to live young. Momotremata comprises the platypus and echidnas.
