There are only two types of egg-laying mammals, known as monotremes. Monotremes include platypuses and echidnas. Platypuses do not have a pouch of any type. Female echidnas develop a rudimentary pouch each breeding season. The pouch is really just a flap of skin into which the echidna lays and incubates the egg. As soon as the young echidna begins to develop its spines, it is transferred into a burrow.
Mammals which have a pouch feature where they carry and nourish their young are known as marsupials.
No. Lemurs are not marsupials, but placental mammals.
No. Giraffes are placental mammals. Unlike marsupials, the female does not have a pouch.
No. Baboons are placental mammals, not marsupials.
Neither. Bats are placental mammals, so they neither have a pouch, nor do they lay eggs.
This would depend on whether the particular insectivore in question was a marsupial or not. Mountain pygmy possums, for example, are marsupials and insectivores, and they carry their young in a pouch. The only exception to this is the numbat, an Australian insectivore and a marsupial which does not have a pouch. Hedgehogs, on the other hand, are an example of placental mammals which are insectivores, but do not belong to the marsupial family; therefore, they do not have a pouch.
These are marsupials, most of which then carry their young in a pouch while the joeys continue to develop.
Both spiny anteaters (echidnas) and wombats have a pouch. Wombats are marsupials, like most pouched mammals. Echidnas are not marsupials, but monotremes. Monotremes are egg laying mammals. Echidnas have a pouch so they can carry the egg they lay and, once the egg hatches, the baby echidna.
Marsupials are a group of mammals characterized by giving birth to relatively undeveloped young, which then typically continue to develop in a pouch on the mother's body. Examples include kangaroos, koalas, and opossums.
http://en.wikipedia.org/wiki/Marsupial Marsupialsare an infraclass of mammals, characterized by a distinctive pouch (called the marsupium), in which females carry their young through early infancy.
For a start, the kangaroo does not use "his" pouch for anything. Only the female kangaroo has a pouch. This pouch is not used to just "carry" the joey, but it acts as the womb does in placental mammals, protecting and nurturing the young joey while it is developing. It has no other function apart from this. It is not used to collect food or for any other purpose.
Placental mammals, also known as eutherians, carry their offspring to term inside the body. They are different from the marsupials, which give birth to immature young which continue their development in a pouch, and monotremes, which are egg-laying mammals.Placental mammals include all members of the canine family, felines, equines, bovines and other livestock, camels and many other mammals.
