Echidna, the spiny anteater, is a monotreme that lives in Australia and in New Guinea. They are the living members of the family Tachyglossidae.
An Echnida looking for food
Echnidas have a long, tube-like mouth with a sticky tongue, and they are also covered in spines. They have mammary glands, and lay eggs.
The echidna has a method of protecting itself. With its long, sharp claws, they quickly dig a hole until only their spines are showing when they are hiding in the hole. The predator will not be able to get it without injuring itself on the spines. When there is a fire, the echidna will dig down out of reach of the fire.
