The platypus is nothing like a bird.
It is an egg-laying mammal. The eggs it lays are soft-shelled and leathery, unlike a bird's eggs, which are hard-shelled. There are some general characteristics which are similar. Birds and platypuses are both air-breathing endothermic vertebrates. Birds and platypuses both have a cloaca, a single vent for both reproduction and waste.
The platypus is not a reptile - it is an egg-laying mammal.
It is a mammal
platypus
Platypus eggs are soft and leathery, rather than hard-shelled.
The only reptile-like characteristic which platypuses have is the fact that they reproduce by laying soft-shelled, leathery eggs (and not all reptiles lay eggs, either). Apart from that, these creatures fit all the characteristics of mammals.
No because it lays eggs. The only mammal that lays eggs is the platypus. It is a reptile.
No. A crocodile is an egg-laying reptile. A platypus is an egg-laying mammal.
The platypus species is very old, so it still has some of the early "primitive" traits of the reptile ancestors despite being considered a mammal.
No, a platypus does not have scales. It has dense, sleek, waterproof fur.

Both the dolphin and platypus are mammals for one very simple reason: they both suckle their young on mothers' milk. this is one of the defining charactersitics of mammals.because dolphins spend all their time in the water, it is difficult to conceive that it is a mammal, and that it could suckle its young on mothers' milk. And the platypus is often wrongly thought of as a reptile or a bird because it lays eggs. Its misnomer "duckbilled platypus" has a large part to play, too. Its bill is a different shape and has a very different function to that of a duck.
