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.
All placental animals are mammals. Placental mammals are the most successful of the major mammal groups (the other two being the marsupials and the monotremes). Everything from rodents to dogs to cows and even elephants, even you, are placental mammals. In fact, they are found on every continent and in virtually every habitat on Earth.
No. There are no golden moles in Australia. There are no true moles in Australia, as moles are placental mammals, but there are two species of marsupial mole, known as the Itjaritjari and the Kakarratul.
Yes, they are placental mammals. Most mammals are placental. The other two options are marsupial mammals (mammals with a pouch) and monotreme mammals (mammals that lay eggs).
No. Most mammals native to Australia are marsupials.Australia is home to about 90 species of bats, which are of course the only true flying mammals, and they are placental mammals. There are also about ten species of native mouse which are rodents, not marsupials, as well as various marine mammals such as dolphins and dugong. There are also the two monotremes, or egg-laying mammals, which include the echidna and the platypus.Although some placental mammals are native to various New Guinean islands, the placental mammals that are found on Australia, like the Red Fox, were introduced by settlers within the last few centuries. The Dingo is commonly believed to be a native Australian animal, but it is not truly native, having come with the Aborigines when they first arrived.
No. Marsupials are just one of three groups of mammals. The other two are monotremes and placental mammals. The vast majority of modern mammals are placental.
Almost all mammals are 'placental'. Humans, tigers, dogs, cats, cows, mice, elephants, etc.
No, not all mammals are placental. There are two other groups of mammals: the monotremes and the marsupials.Monotremes are egg-laying mammals, and marsupials are generally pouched mammals, although not all marsupials have fully developed pouches.
There are no placental mammals which lay eggs.The only two egg-laying mammals in existence are the platypus and the echidna, which are classed as monotremes.They are still classified as mammals because they feed their young on mothers' milk - a characteristic unique to mammals alone.
The echidna and the platypus are non-placental mammals. They are monotremes, or egg-laying mammals. Kangaroos, wallabies, koalas, bandicoots, wombats and Tasmanian devils are just a few other non-placentals, as they are marsupials.
No, echidnas are not placental mammals. They are classified as monotremes. They are mammals as they feed their young on mothers' milk, but they lay eggs. The echidna is unique in this way as there is only one other monotreme known, the platypus. Echidnas do not have teats, but a milk patch through which milk seeps when they are feeding their hatched young.
Raccoons are mammals so they are born alive
No. Raccoons are placental mammals and possums are marsupials. The two are from completely different families.
