monotremes

These monotremes are totally absent in the rest of the world.

There are two surviving families of monotremes, with five living species.

Monotremes are arranged by size with the largest at the top.

The platypus is one of the few remaining monotremes on Earth.

Monotremes, for example, lay eggs which protect the young until they are fully developed.

The construction of the lower jaw differs from existing monotremes.

The only surviving animals in this subclass are the Monotremes.

But much of what biologists surmised about monotremes over the years has turned out to be wrong.

Among the monotremes the platypus has the most acute electric sense.

Much of the argument is based on monotremes, the egg-laying mammals.

Its eggs were probably small and leathery, a condition still found in monotremes.

Except for monotremes, the young of all mammals develop within the body of the mother.

Almost all its native mammals (except the two monotremes) are marsupials.

The monotremes are the only mammals that lay eggs.

For example, all gargoyle females lay eggs just as monotremes do.

Monotremes are a group of mammals that form the order Monotremata.

Monotremes are the only mammals that lay eggs, but they also feed their babies with milk.

These mammals are called monotremes because they have a common rear opening known as the cloaca.

That is the simple reason why Australia has most of the world's marsupials and all the world's monotremes.

No mammals except for monotremes reproduce like this.

The monotremes are a mixture of primitive and advanced traits, a situation known as mosaic evolution.

If so, that may explain why the patches from which monotremes secrete milk are hairy.

Monotremes, although part of the mammalian class, do have interclavicles.
