Echidnas (/ ɪˈkɪdnəz /), sometimes known as spiny anteaters, [1] are quill-covered [2] monotremes (egg-laying mammals) belonging to the family Tachyglossidae / tækiˈɡlɒsɪdiː /, living in Australia and New Guinea.

Echidnas are some of the most unique animals in the world.

Everything you should know about the Echidna. The Echidna looks like a cross between a hedgehog and an anteater, and is a rare mammal that lays eggs.
