There are only two surviving examples of monotremes. One is the echidna (or spiny anteater). What is the other?
Echidna Outback, essentially anywhere ants and termites are available. It is smaller than the "Zaglossus" species, and it has longer hair. Despite the similar dietary habits and methods of consumption to those of an anteater, there is no evidence supporting the idea that echidna-like monotremes have been myrmecophagic (ant or termite-eating) since the Cretaceous. The fossil evidence of invertebrate-feeding bandicoots and rat-kangaroos, from around the time of the platypus–echidna divergence and pre-dating "Tachyglossus", show evidence that echidnas expanded into new ecospace despite competition from marsupials. The genus "Megalibgwilia" is known only from fossils: Aboriginal Australians regard the echidna as a food

Short-beaked echidna The short-beaked echidna ("Tachyglossus aculeatus") is one of four living species of echidna and the only member of the genus Tachyglossus. It is covered in fur and spines and has a distinctive snout and a specialized tongue, which it uses to catch its insect prey at a great speed. Like the other extant monotremes, the short-beaked echidna lays eggs; the monotremes are the only group of mammals to do so. The short-beaked echidna has extremely strong front limbs
