The first of a number of Australian animals on this list, the echidna, sometimes known as spiny anteaters, is one of two members of the monotreme order of mammals, which means that it does not birth live young, but lays eggs. They are covered in spines, and have long snouts lined with electroreceptors, a feature only found on land in echidnas and platypuses.
