What are 2 monotremes that lay eggs?

Only two kinds of egg-laying mammals are left on the planet today—the duck-billed platypus and the echidna, or spiny anteater. These odd “monotremes” once dominated Australia, until their pouch-bearing cousins, the marsupials, invaded the land down under 71 million to 54 million years ago and swept them away.

What are the 3 species of monotremes?

Monotremes are a unique order of mammals that includes only three extant species: the duck-billed platypus (Ornithorynchus anitinus), the short-billed echidna (Tachyglossus aculeatus), and the western long-billed echidna (Zaglossus bruijni).

What do monotremes do?

The reason that odd, egg-laying mammals still exist today may be because their ancestors took to the water, scientists now suggest. The egg-laying mammals — the monotremes, including the platypus and spiny anteaters — are eccentric relatives to the rest of mammals, which bear live young.

Where are monotremes found?

The only surviving examples of monotremes are all indigenous to Australia and New Guinea although there is evidence that they were once more widespread, as Monotrematum is known from the Paleocene of South America. The extant monotreme species are the platypus and four species of echidnas.

What two Australian animals are monotremes?

Echidnas and platypuses are the only surviving monotremes (egg-laying mammals) in the world.

What are the 3 types of mammals?

Mammals are divided into three groups - monotremes, marsupials and placentals, all of which have fur, produce milk and are warm-blooded.

What are the 5 mammals that lay eggs?

Only five species of animals share this extraordinary egg-laying trait: the duck-billed platypus, western long-beaked echidna, eastern long-beaked echidna, short-beaked echidna, and Sir David's long-beaked echidna. All of these monotremes are only found in either Australia or New Guinea.
