Examples of placental mammals are
Not all mammals are placental.
The term "placental mammals" refers to those mammals which give live birth to fully developed young. these young have been nourished via the placenta, usually for several weeks to several months or longer, depending upon the size of the mammal.
Placental mammals may be distinguished from marsupials by the fact that marsupials are born extremely undeveloped. The blind, hairless, bean-sized joey makes an arduous journey into the mother's pouch (although not all marsupials have pouches) where it latches on to a teat. The teat then swells in its mouth, securing it firmly in place, while it continues its development for several more months.
The third group of mammals are the egg-laying mammals, the monotremes. These include platypuses and echidnas.
Egg laying animals such as birds, frogs, fishes, chickens, perry the platypus (agent p), crocodiles, alligators, snakes, salamander, lizards, turtles, siren, mud puppy, hell banders, and caecillians
Oviparous animals lay eggs: birds, a large number of reptiles, fish and amphibians.
Viviparous animals bare live young that have developed in a womb or internally in another internal organ system (all mammals except monotremes, some reptiles, fish and amphibians, etc.).
All mammals except for monotremes are viviparous. Monotremes are platypuses and echidnas: therefore, any mammal that is not a platypus or echidna is viviparous.
Actual examples would be cats, dogs, horses, kangaroos, koalas, gerbils, gophers, beavers, dolphins, whales, rats, shrews, porcupines, armadillos, etc.
A viviparous animal carrys the embryo inside the mother and the mother gives birth to live young. Like cows and horses.
Ovoviviparous animals are animals that develop within eggs. The eggs stay in the mother's body until it is time to hatch. Examples include reptiles, fish and sharks.
All mammals except the echidna and platypus are viviparous.
Most mammals are placental...marsupial mammals and monotremes are not placental.
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
Yes. Shrews are placental mammals.
A rabbit is a placental mammal.
Dolphins are placental mammals.
Seals are placental mammals, as the young complete their development within the mother's uterus, attached to a placenta. They do not have a pouch like most marsupials, and they do not lay eggs like monotremes.
Neither. Bats are placental mammals, so they neither have a pouch, nor do they lay eggs.
Yes, leopards are placental mammals as are most mammals.
Most mammals are placental. In Australia, however, almost all mammals are marsupials.
