Yes. The platypus is the only mammal with a bill of any sort.
The only mammal that can sting is the Platypus. Male platypuses have spurs on their back ankles with from which they can inject poisonous DLPs (defensin-like proteins). Female platypuses and echidnas also have these back ankle spurs, but only male platypuses can use them.
Platypuses do not have green blood. No mammal has green blood.
Platypuses are solitary animals, and are the only mammal occupying its particular niche. Platypuses are therefore not "friends" with any other animal.
A platypus IS a mammal. The only difference is that platypuses are egg-laying mammals, or monotremes. In every other sense, they are completely mammals.
Platypuses and echidnas are the only two egg-laying mammals. Neither of them flies.
Platypuses are one of only two mammals to lay eggs. The other is the echidna. The platypus is also the only semi-aquatic mammal equipped with a multi-tasking bill. It has electroreceptors in its bill, which enable it to detect electrical impulses from underwater crustaceans, which it digs out of the mud, using its bill, and on which it feeds, crushing them in grinding plates.
No. A platypus is a mammal which lays eggs. It is semiaquatic, and found in eastern Australia, including the island state of Tasmania. It has a flat tail, feet with sharp claws and retractable webbing, and a snout that resembles a duck's bill. It is sometimes call the duckbilled platypus, but not within Australia.The reason the platypus may be mistaken for a bird is that it is one of only three species of egg-laying mammals, or monotremes. It is a mammal because it has fur, and because it feeds its young on mothers' milk.
Two characteristics that might cause people to think platypuses are not mammals are:1. The fact that they reproduce by laying soft-shelled leathery eggs - the echidna is the only other mammal to share this trait.2. Their strange, flat bill which is equipped with electroreceptors for hunting their food.Platypuses are mammals because they are warm-blooded vertebrates with a covering of fur. They suckle their young on mothers' milk, which is the defining characteristic of a mammal.
Yes. The echidna is a monotreme, or egg-laying mammal. Platypuses and echidnas are the only egg-laying mammals.
No. This is a characteristic of amphibians. the only mammals to lay eggs, platypuses and echidnas, do not lay them in a jelly-like substance.
Not at all. Platypuses are mammals and alligators are reptiles. There is no part-mammal, part-reptile species. Furthermore, there are no alligators in Australia, but only crocodiles.
No. A raccoon is a placental mammal, meaning it gives birth to live young. Monotremes are egg-laying mammals. Only platypuses and echidnas are monotremes.
