All three species of monotremes, which comprise the platypus, short-beaked echidna and long-beaked echidna, reproduce sexually. Monotremes are egg-laying mammals, so platypuses and echidnas lay eggs in order to reproduce.

How are monotremes unusual mammals?
They are the only mammals that lay eggs in order to reproduce.
Are hedgehogs monotreme?
No. Hedgehogs are not monotremes (egg-laying mammals), as they do not lay eggs in order to reproduce. They are placental mammals. The only monotremes are the platypus and the echidna.
Why are monotremes special?
Monotremes are special because they are a very small group of mammals which lay eggs. Most mammals give live birth, but monotremes lay soft-shelled, leathery eggs in order to reproduce.
What is a monotreme and what is its method of birth?
Monotremes are egg-laying mammals: this, they reproduce by laying eggs, not by giving birth. The only known monotremes are the platypus, short-beaked echidna, and the long-beaked echidna.
What scientific name is given to those living beings who reproduce by laying eggs?
For all animals that reproduce by egg-laying, the word is "oviparous". The word for mammals that reproduce by laying eggs is "monotremes".
How do mammals reproduce their young?
Most mammals give live birth, except for the platypus and echidna. They lay eggs, and are called monotremes.
How are monotremes and other mammals the same?
Monotremes are mammals; therefore they share many similarities: they are warm-blooded, have hair, possess high metabolisms - all characteristics that define what a mammal is. The defining characteristic of a mammal is that it suckles its young on mothers' milk, and monotremes certainly do this.The key difference between the two is that monotremes reproduce by laying eggs rather than give birth.
Are mammals born in eggs?
Most mammals are not hatched from eggs. Only the monotremes, or egg-laying mammals, reproduce by external eggs. Monotremes include just the platypus, the long-beaked echidna and the short-beaked echidna.
Do Echidna lay eggs?
Yes. Like the platypus, the echidna is a monotreme, or egg-laying mammal. Monotremes are the only known mammals that reproduce by laying eggs.
Do mammals lay eggs and how do they reproduce?
Generally, mammals are characterised by giving birth to live young. There is a very small group of egg-laying mammals known as monotremes. Monotremes, which include platypuses and echidnas, lay soft-shelled, leathery eggs which hatch after ten days.
Do echidnas give birth to live young?
No. Echidnas are monotremes, meaning they are egg-laying mammals. They do not give birth to live young, but lay eggs in order to reproduce.
Do platypuses reproduce by laying eggs?
Yes. Platypuses are monotremes, or egg-laying mammals, so they do not give birth to live young. The only other monotreme is the echidna.
