No, platypuses are monotremes. This means they are mammals which lay eggs, instead of giving birth to live young. The only other monotreme is the echidna.
Yes. These creatures are all mammals. Platypuses are monotremes (egg-laying mammals) while the others are placental mammals.
No: dolphins are placental mammals. The only monotremes are platypuses and echidnas.
Not even remotely. Platypuses are monotremes, or egg-laying mammals; giant pandas are placental mammals. The only connection between the two animals is that they are both mammals.
No. Chinchillas are rodents. Only platypuses and echidnas are monotremes.
None. People are placental mammals; platypuses are monotremes.
Chimpanzees do not lay eggs. Chimpanzees are placental mammals, meaning they give birth to live young. The only egg-laying mammals (monotremes) are platypuses and echidnas.
Platypuses are completely within their own category - a sub-group known as monotremes. Platypuses are definitely not a type of beaver. Beavers are placental mammals, while platypuses are monotremes, which are egg-laying mammals. Ducks are not even remotely related to platypuses, as they are birds.
No. Mice are placental mammals, meaning they give birth to live young. The only egg-laying mammals (monotremes) are platypuses and echidnas.
Yes, they do; the sub-class Eutheria (placental mammals) includes all orders of mammals except monotremes (platypuses and echidnas) and marsupials (opossums, kangaroos, etc.). Cetaceans (whales, dolphins and porpoises) are included.
No. Borugo rodents are placental mammals, meaning they give birth to live young. The only egg-laying mammals (monotremes) are platypuses and echidnas.
No
No. Platypuses are not placental mammals, but monotremes, meaning that they reproduce by laying eggs. The young do not develop in the mother's womb, and therefore do not receive their nutrition via an umbilical cord.
