Why are plancetals more successful than marsupials and monotremes?
Because placentals are the largest number of mammals.
Is a grizzly bear a marsupial?
All marsupials have a pouch. All monotremes are egg laying mammals. Placental mammals give birth to live young, but do not have a pouch. Bears do not have a pouch, and they give birth to live young rather than laying eggs, so they are placental mammals.
Are seals monotremes?
Monotremes are mammals which lay eggs rather than give birth, therefore a seal is not a monotreme.
Is a bat a monotreme?
No. Monotremes are mammals which lay eggs rather than give birth. The only monotremes are the echidna and the platypus. Bats give live birth, so they are not monotremes.
Do kangaroos have eggs or live birth?
They are born not in an egg, they are born as kangaroos just like humans are born as humans and not in an egg
Are echidnas marsupials?
No, echidnas are not marsupials. They are monotremes, that is, egg-laying mammals. However, during breeding season, the female does develop a rudimentary pouch in which she incubates her egg, but this is really nothing more than a flap of skin.
Does wallaby lay eggs?
Wallabys give birth to a joey about the size of a kidney bean. The joey crawls up a trail that the mother licks on her belly up into the pouch. The joey crawls into the pouch and attaches to a nipple and remains in the pouch for several months. Wallabys belong to the Marsupials. That group includes kangaroos, opossums, koalas, wombats and some other species found in Australia.
Why are some mammals that lay eggs classified as mammals?
Monotremes lay eggs, as do reptiles. Monotremes' limbs go outward (rather than downward) from their main body, which is also true for reptiles. Monotremes lack a corpus callosum (which placental mammals have), as do reptiles. Monotremes and reptiles both have cloacas, while placental mammals have separate openings for urination and defecation. This evidence all shows monotremes to be a link between reptiles and mammals, but we now think that monotremes just evolved from an earlier branching from the mammalian tree of lineage than the marsupials and placental mammals evolved from. Monotremes are not a link between reptiles and mammals.
Are chiropterans placentals marsupials or monotremes?
Marsupials, monotremes and placental mammals are all sub-groups of mammals. They share the following characteristics:vertebrateswarm-bloodedhave fur, skin or hairbreathe through lungs (not gills)the young feed on mother's milkThe major differences, however, include:monotremes are the only mammals which lay eggsmarsupial young are born undeveloped and continue most of their growth and development whilst they are in the mother's pouch, attached firmly to the teat for several months, where they receive all their nutrients.
What don't female monotremes have?
Female monotremes are the only mammals which do not have nipples for the young mammals to suckle from. Monotremes, which are the echidnas and platypuses, feed their young on mothers' milk which is exuded from modified sweat glands, rather than from well-formed teats. Female monotremes also do not have two external openings. They have just one external opening, the cloaca, for both waste elimination and for reproduction. The cloaca leads to the urinary, faecal and reproductive tracks, all of which join internally, and it is the orifice by which the female monotreme lays her eggs.
Is a chimpanzee a monotreme?
Monotremes are mammals which lay eggs rather than give birth, therefore a chimpanzee is not a monotreme.
Is an elephant a monotreme?
Monotremes are mammals which lay eggs rather than give birth, therefore an elephant is not a monotreme.
