Looks familiar huh?? It’s actually the Australian version of the anteaters and it is called an Echidna. These are small mammals that are covered with coarse hair and spines, differentiating them from the anteaters of South America. Weird facts about them: 1. Female echidna lays egg — one of the two mammals that does so! The other is the platypus. 2. Male echidnas have a four-headed penis, but only two of the heads are used during mating. The other two heads “shut down” and do not grow in size. The heads used are swapped each time the mammal has sex. NICE! Hehe!
