The echidna is an odd animal for many reasons. It looks like a cross between a hedgehog, a platypus and an anteater (and indeed it is commonly known as the ?spiny anteater?). Additionally, the females of this mamalian species lay eggs, which is really rare ? in fact, the only other mammal known to do this is the platypus (egg-laying mammals are called monotremes), so already we can see that these are special ickly cuties. But what is perhaps most bizarre about this little Australian waddler is its penis. Dare you look? GO ON SCROLL DOWN I DARES YE!
