There are two animals that are known as monotremes (mammals that lay eggs instead of giving birth to live young). One is the platypus, the other is the echidna, sometimes known as a spiny anteater, coz it well, eats ants!
This one was intent on hiding from me...but not doing a very good job of it! I stayed for a short while, hoping to get a better photo, but it wasn't to be. It's nose is at bottom right of the picture.
