mammals lay eggs?

Question

platupuses are mammals thank you very much and they lay eggs so what now?

Everyone says they dont just proving my point.

Answer 1

A Platupus is a "freak of nature" they aren't exactly catagorized as anything because to be a mamal an animal has to have fur/hair, mammary glands and give live birth...

Hope this helps...GOOD LUCK!!!

Answer 2

Egg-laying mammals are monotremes (Order Monotremata). The two Families are the platypus (family Ornithorhynchidae, genus Ornithorhyncus, species O.anatinus) and the echidna (family Tachyglossidae). There is only the one spp. of platypus (modern day anyway), however there are two GENERA of echidna. Only one spp. (short-beaked) is found in Australia (and also parts of New Guinea), but there are 3 living spp. found in NG (long-beaked) and 2 extinct spp. So, all together if you're talking the number of monotreme species (and we'll say living) there are actually 5 spp. Did you also know that an ancient platypus was also found in South America (I have actually seen a fossil in class) but had teeth and was larger. It is an interesting debate as to whether monotremes spread from Sth America to Australia or the other way round!

Answer 3

all mammals have eggs... us included.

from wiki:
The four species of echidna, along with the Platypus, are the only egg-laying mammals. The female lays a single soft-shelled, leathery egg twenty-two days after mating and deposits it directly into her pouch. Hatching takes ten days; the young echidna, called a puggle, then sucks milk from the pores of the two milk patches (monotremes have no nipples) and remains in the pouch for forty-five to fifty-five days, at which time it starts to develop spines. The mother digs a nursery burrow and deposits the puggle, returning every five days to suckle it until it is weaned at seven months.

Answer 4

Well, there always has to be the exception to the rule. When it comes to Australia and New Zealand, I really think God just took all the leftover pieces and parts and smashed 'em all together and said, "this is what you get." Australia and New Zealand have some very strange animals. So, if platypus really do lay eggs, then how come we don't have the Easter Platypus bringing eggs? Then, at least, it would be true!

Answer 5

Laying eggs has nothing to do with the definition of "mammal."

Answer 6

there are two mammals that lay eggs, the platypus and the Echidna. They are called Monotremes, and are only found near Australia. They are simply different than other mammals.
