- What kind of mammals carry immature offspring in pouches? These are the marsupials, which include animals such as kangaroos, koalas, wombats, possums, wallabies and Tasmanian devils, to name a few. Not all marsupials have fully deve … loped pouches, but all marsupials give birth to very undeveloped young.

- They are warm-blooded and mothers make milk for thie young.    All mammals have fur somewhere on their bodies, and the females of all mammal species have mammary glands w…ith which they feed their young with milk. These are the two defining features of mammals. Most mammals give birth to live young, but the five species of monotremes (which have the above two characteristics) lay eggs instead. Making the world better, one answer at a time.

- A horse and donkey are not the same species and the mule is born sterile. Another example is a lion and tiger, they are not the same species either, but they can produce a liger. A cat and rabbit can mate but it is most often done artificially (by humans), and their offspring will be born sterile.

Mammals There are three main classes of mammals: placentals, marsupials and monotremes. Most mammals give birth to live young using a placenta to carry the baby during gestation (i.e., placentals). Marsupials have a pouch in which females carry their young through early infancy.ore specifically, you are a probably a primate of the human family. The term mammal comes from the fact that female mammals have mammary glands that produce milk to feed their young offspring. Mammals are warm-blooded, air-breathing animals that have hair or fur on their body.

Examples of Marsupial Mammals The most well-known defining feature of marsupial mammals are the females' pouches. They give birth to live offspring, but with significantly shorter gestation periods than placental mammals. Offspring are born as not much more than embryos.angaroos. Kangaroos are probably the most famous marsupial mammals. There are more than 50 different kangaroo species, including red kangaroos, gray kangaroos and some smaller cousins of the same family, like wallabies, wallaroos and quokkas.

Eutheria, the Placental Mammals Placental mammals all bear live young, which are nourished before birth in the mother's uterus through a specialized embryonic organ attached to the uterus wall, the placenta. The placenta is derived from the same membranes that surround the embryos in the amniote eggs of reptiles, birds, and monotreme.

What characteristics do mammals have in common? A Mammal is normally defined as a warm blooded animal with a covering of fur, skin or hair which gives birth to live young who are nourished with milk, and who are vertebrate.… All mammals suckle their young, but there is a sub-group known as monotremes, which are the egg-laying mammals.  A mammal is a animal that is warmblooded vertebrate (which  means a animal with a backbone) It must have at least a little bit  of fur (hair) on its body. Also a mammal's baby must be born alive  and must drink it's mother's milk.

Platypus Facts Most mammals give birth to live young. Platypuses, however, lay eggs. They are a species of primitive mammals called monotremes. Echidnas, or spiny anteaters, are the only other mammals that lay eggs.When the female platypus is ready to have her young, she will burrow down inside the ground on the riverbank and seal herself into one of her tunnel rooms.latypuses (which is the correct plural form, not platypi) have a paddle-shaped tail like a beaver; a sleek, furry body like an otter; and a flat bill and webbed feet like a duck. In fact, the first time a platypus was brought from Australia to Britain, people couldn't believe that it was a real animal.

Opossums are the only marsupial mammals indigenous to North America. Mothers carry their young in the pouch until they're 2 to 3 months old, then they continue carrying offspring around on their backs for about another month or two whenever they venture out of their den.

- Whales are mammals because they give birth to live young, they have fur (although it is very sparse on their body), they have lungs and breath air and they provide milk for their young. You have a lot of interesting questions about marine mammals. Dolphins and other whales are all mammals called cetaceans.

Male Seahorses Act Like Pregnant Mammals, Study Suggests Pregnant male seahorses tend to develop embryos similarly to the way mammals do, new research shows. Pregnant male seahorses tend to develop embryos similarly to the way mammals do, new research shows. In the new study, scientists found a suite of genes that are turned on in the pouches of seahorses to keep the baby healthy and growing. Similar gene activity has been found in the wombs of mammals and even reptiles. As such, the finding could shed light on the evolution of live birth, called viviparity. Seahorse broods

What Animals Stay Pregnant for a Long Time? These gentle giants have the longest gestation period of all mammals, carrying their developing babies for nearly two years before giving birth. Because elephants are the largest land animal in the world with the biggest brains, their long gestation period allows for proper development of the fetus in the womb.

Mammals Monotremes, such as the platypus, are unusual mammals in that they lay eggs to give birth to their young. There are approximately 5,400 species of mammals on Earth, divided into 153 families of animals.ore specifically, you are a probably a primate of the human family. The term mammal comes from the fact that female mammals have mammary glands that produce milk to feed their young offspring. Mammals are warm-blooded, air-breathing animals that have hair or fur on their body.

The Rise of Mammals Deep in their bones, all mammals are related. The earliest known mammals were the morganucodontids, tiny shrew-size creatures that lived in the shadows of the dinosaurs 210 million years ago. They were one of several different mammal lineages that emerged around that time. All living mammals today, including us, descend from the one line that survived.

- Mammals are warm-blooded vertebrates which, with the exception of a few notable species, nurse their young on milk produced by the female’s mammary glands, give birth to live young, and have bodies insulated by hair. Around one in four of the world’s mammals are currently threatened with extinction.

- 1 Placental mammals. 2  In placental mammals, the extraembryonic membranes form a placenta and umbilical cord, which connect the embryo to the mother's uterus in a more elaborate and efficient way. 3  The blood supply of the developing fetus is continuous with that of the placenta. The yolk sac contains yolk — the sole source of food until hatching. 2  Yolk is a mixture of proteins and lipoproteins. 3  The chorion lines the inner surface of the shell (which is permeable to gases) and participates in the exchange of O 2 and CO 2 between the embryo and the outside air.

Gestation Gestation is the carrying of an embryo or fetus inside female viviparous animals. It is typical for mammals, but also occurs for some non-mammals. Mammals during pregnancy can have one or more gestations at the same time (multiple gestations).

- Other animals that have gestation periods closest to that of humans are: dolphins - 276 days, chimpanzee - 237 days and cattle - 280 days. 494. About the Author. The shortest gestation period known in mammals is approximately 12 days. It is shared by the American or Virginian opossum (Didelphis marsupialis); the rare water opossum, or yapok (Chironectes minimus) of northern South America and the eastern native cat (Dasyurus viverrinus) of Australia.
