Tachyglossus
The short-beaked echidna (Tachyglossus aculeatus) is found in southern, southeast and northeast New Guinea. It is found living in almost all Australian environments, from the snow-clad Australian Alps to the deep deserts of the Outback. Its diet is made up of ants and termites. It is smaller than the Zaglossus species, and it has longer hair.
