Short-Beaked Echidna, Tasmania, AustraliaMonotremes are egg-laying mammals. There are only 5 monotremes in the world — the platypus and four species of echidna. This is the short-beaked echidna. I spotted him/her on the side of the road, while driving to Cradle Mountain National Park in Tasmania, Australia.
