Baby Echidna, Taronga Zoo, Sydney, New South Wales, Australia

The three living Zaglossus species are endemic to New Guinea. They are rare and are hunted for food. They forage in leaf litter on the forest floor, eating earthworms and insects. The species are:
- Western long-beaked echidna (Z. bruijni), of the highland forests;
- Sir David's long-beaked echidna (Z. attenboroughi), described in 1961 and preferring a still higher habitat;
- Eastern long-beaked echidna (Z. bartoni), of which four distinct subspecies have been identified.
