Monotremes are the only mammals that lay eggs.
Both platypuses and echidnas are monotremes. The name monotreme is derived from two Greek words meaning "one-holed", because they have just one external opening, the cloaca, for both waste elimination and for reproduction. The cloaca leads to the urinary, faecal and reproductive tracks, all of which join internally, and it is the orifice by which the female monotreme lays her eggs. This is different from other mammals, which have two openings - one for reproduction, and one for waste.
They are different from other animals because they are the only animals that lay eggs and feed milk to their young ones.They also have hairs.They are mammals that lay eggs.
The mammal groups differ in how their young develop. Monotremes lay eggs. Mammals are endothermic vertebrates that have skin covered with fur or hair, and a four chambered heart
Monotremes, that includes the platypus and the echidnas, lay eggs. All other mammals, including placentals and marsupials, give live birth.
A monotreme is a kind of mammal. It just has a different type of reprooductive system as most other mammals.
Monotremes are the only mammals that give birth to their young in eggs
Yes, they are placental mammals. Most mammals are placental. The other two options are marsupial mammals (mammals with a pouch) and monotreme mammals (mammals that lay eggs).
No, platypuses are monotremes. This means they are mammals which lay eggs, instead of giving birth to live young. The only other monotreme is the echidna.
A monotreme is a specialised mammal that lays eggs, but has all the other characteristics of mammals. They are platypus and echidna.
It is a monotreme, this means it's one of only 2 types of mammals that lay eggs. The other is the platypus.
Monotremes are mammals which lay eggs, as opposed to all other mammals which give birth to live young. The only mammals which are monotremes are the platypus and short-beaked echidna of Australia, and the long-beaked echidna of New Guinea.
The spiny anteater, more correctly known as the echidna,is a monotreme. This means it is an egg-laying mammals, one of only two such types of animals in the world. The other monotreme is the platypus.
The platypus is a monotreme, and of the order monotremata.Together with the short-beaked and long-beaked echidna, the platypus is one of the few egg-laying mammals in the world.
Yes, there is. The echidna is also a monotreme.
The echidna, also known as the spiny anteater, is different from most other mammals because it is a mammal that lays eggs. It is a monotreme, meaning it is an egg-laying mammal. The only other mammal species which lays eggs is the platypus.
Yes. Platypuses are monotremes, or egg-laying mammals, so they do not give birth to live young. The only other monotreme is the echidna.
