Most mammals are placental. In Australia, however, almost all mammals are marsupials.
Kangaroos are non-placental mammals
Terrestrial placental mammals do have fur or hair. Marine placental mammals do not.
No.
No. Primates are a group of placental mammals, but there are many placental mammals that are not primates.
placental mammals are the most famous mammals
There are many marine mammals, all of which are placental, including dolphins, and the dugong, or sea-cow. The only placental mammals native to Australia are bats, of which there are over 80 species, and native hopping mice (rodents, not marsupials), of which there are several species. Dingoes are not truly native, not having originated here.
Most mammals are placental...marsupial mammals and monotremes are not placental.
Australia had no placental mammals, so marsupials diversified. New Zealand had neither placental mammals or marsupials (with the exception of bats), so birds diversified and took on many of the ecological roles usually played by mammals.
Yes. Shrews are placental mammals.
A rabbit is a placental mammal.
Monotremes were among the earliest mammals to evolve. However, in most of the world, all monotremes went extinct as a result of competition with more advanced placental mammals. Australia and New Guinea, however, have been so isolated that there were nearly no placental mammals (except for bats) until humans introduced them. The lack of competition from placental mammals allowed monotremes to survive in Australia.
