Australia is home to two of the five extant species of monotremes and the majority of the world's marsupials (the remainder are from Papua New Guinea, eastern Indonesia and the Americas). The taxonomy is somewhat fluid; this list generally follows Menkhorst and Knight [ 1 ] and Van Dyck and Strahan, [ 2 ] with some input from the global list ...
Koala Humpback whale. A total of 386 species of mammals have been recorded in Australia and surrounding continental waters: 364 indigenous and 22 introduced. [1] The list includes 2 monotremes, 154 marsupials, 83 bats, 69 rodents (5 introduced), 10 pinnipeds, 2 terrestrial carnivorans (1 recent introduction, and 1 prehistoric introduction), 13 introduced ungulates, 2 introduced lagomorphs, 44 ...
The mammals of Australia have a rich fossil history, as well as a variety of extant mammalian species, dominated by the marsupials, but also including monotremes and placentals. The marsupials evolved to fill specific ecological niches, and in many cases they are physically similar to the placental mammals in Eurasia and North America that ...
Population estimate is only for the areas within Australia where commercial harvesting occur. The actual national populations would be significantly higher. Red kangaroo: Osphranter rufus: LC >10,848,470 (2021) [5] Population estimate is only for the areas within Australia where commercial harvesting occur.
For instance, most Australian marsupials outside the order Diprotodontia have a varying number of incisors between their upper and lower jaws. Early marsupials had a dental formula of 5.1.3.4/4.1.3.4 per quadrant, consisting of five (maxillary) or four (mandibular) incisors, one canine, three premolars, and four molars, totaling 50 teeth.
The latter subclass is divided into two infraclasses: pouched mammals (metatherians or marsupials), and placental mammals (eutherians, for which see List of placental mammals). Classification updated from Wilson and Reeder's "Mammal Species of the World: A Taxonomic and Geographic Reference" using the "Planet Mammifères" website. [1]
