The new pilgrims that join all the rest of the mammals here represent only three genera: Ornithorhynchus anatinus, the duckbilled platypus which lives in Eastern Australia and Tasmania; Tachyglossus aculeatus, the short-beaked echidna which lives all over Australia and New Guinea; and Zaglossus, the long-beaked echidna, which is confined to the highlands of New Guinea.
