Yes. The echidna is a monotreme, or egg-laying mammal. Platypuses and echidnas are the only egg-laying mammals.
Egg laying mammals are the mammals classified as monotremes. These include the Platypus and various species of Echidna.
No.The vast majority of mammals do not lay eggs at all. There are only three egg-laying mammals, which are known as monotremes: the platypus, the short-beaked echidna and the long-beaked echidna. Not one of these species lays its eggs in the water.
Platypuses and echidnas are the only mammals that lay eggs. These mammals belong to the group of mammals known as monotremes. Platypuses and echidnas lay eggs just once a year. The platypus lays 1-2 eggs, while the echidna lays a single egg each year.
There are only two egg-laying mammals - the platypus and the echidna - and they do not lay eggs daily. These animals lay eggs only during the breeding season, which occurs once a year. The platypus lays between one and three eggs each year, while the echidna usually lays just a single egg.
By definition, mammals have live young, with the exception of the three species of monotremes.These include the platypus and the short-beaked echidna, native to Australia, and the long-beaked echidna, native to New Guinea (there are three sub-species of the long-beaked echidna). These animals lay eggs, but still feed their young on mother's milk.Eutheria (placental mammals) and marsupials do not lay eggs.
There is no such thing as a bird that is a mammal. Mammals are one classification, and birds are another. All birds lay eggs. Most mammals do not lay eggs. The only exceptions are the monotremes, which include just the platypus and the echidna.
The ostrich lays the biggest but most dinosaurs laid bigger eggs than that.
None - because there are two types of mammals which lay eggs. Monotremata is the order which contains the echidna and the platypus, both of which are egg-laying mammals. Monotremes is the order of mammals that lay eggs rather than giving live birth.
The echidna usually lays just a single egg at a time.
The echidna is a monotreme, which is an egg-laying mammal. Most mammals give live birth, but only the echidna and platypus are egg-laying mammals.
Platypuses are one of the 2 mammals that lay eggs. The other is the echidna.
Both the echidna and the platypus are mammals that lay eggs. They are in a subclass of their own, the monotremes, which are the egg-laying mammals. In every other respect, they exhibit the characteristics of mammals, such as having fur, being warm-blooded vertebrates and feeding their young on mothers' milk.
