Monotremes are egg-laying mammals. The echidna lays eggs in order to reproduce, and it is a mammal because it has fur and suckles its young on mothers' milk.
The name monotreme / Monotremata 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. Echidnas have this physiology.

Very few mammals, such as the platypus, are monotremes.
Echidnas are hatched. They are monotremes, or egg-laying mammals.
No: dolphins are placental mammals. The only monotremes are platypuses and echidnas.
Monotremes are covered with skin, but over the skin they have fur. Both platypuses and echidnas have fur, and echidnas also has sharp spines.
Platypuses and echidnas are monotremes, or egg-laying mammals.
Platypuses and echidnas are both monotremes.
Yes. Both types of monotremes - platypuses and echidnas - have fur and lay eggs. In addition, echidnas have sharp spines, but these protrude from its body through a layer of thick fur.
Platypuses are monotremes and their nearest relatives are Echidnas.
No; echidnas, unlike porcupines, are not members of the rodent family. Echidnas are monotremes, or egg-laying mammals.
No. A moose is a placental mammal, meaning it gives birth to live young. Monotremes are egg-laying mammals. Only platypuses and echidnas are monotremes.
Yes. Platypuses and echidnas are the only monotremes, or egg-laying mammals.
A monotreme. Monotremes consist of platypuses and echidnas.
No. The now-extinct Tasmanian Tiger, more properly known as the Thylacine, was a marsupial. The only known monotremes are platypuses and echidnas.
