What kind of creature is monotreme?

Answer 1

The classification of monotremes is as follows:

Kingdom: Animalia

Phylum: Chordata

Subphylum: Vertebrata

Class: Mammalia

Subclass: Prototheria

Order: Monotremata

Answer 2

Monotremes are mammals that lay eggs and give milk but do not have discrete mammary glands. They were once considered to be "primitive" mammals but the scientific community no longer regards them in this way.

There are just three species of monotreme: the platypus, the short-beaked echidna and the long-beaked echidna.

There are then three sub-species of the long-beaked echidna - the Eastern long-beaked echidna, Western long-beaked echidna and Sir David's long-beaked echidna.

Answer 3

Both platypuses and echidnas are classified as 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.

Answer 4

The only mammals which are monotremes (egg-laying mammals) are the platypus and short-beaked echidna of Australia, and the long-beaked echidna of New Guinea.

Answer 5

Monotremes are mammals that lay eggs. Only the echidnas and the platypus are in this category.
