Most male animals have penises. But not all of them are reserved exclusively for sex - in fact, there are a number of animals that use their penises as tools, too. Some penises have evolved to give the animal the best chance of successfully inseminating a female. Others help ensure that the guy can make it through mating season with all his limbs intact. And some uses for animal penises aren't sexual at all. A few creatures sport members that can pick up objects or even scratch an itch.
In the end, all penises share the same purpose: to pass on genes and make sure a new generation of critters is born. But if you have it, use it, right? That seems to be the mindset of these animals with Swiss Army penises.
If you thought elephants had just one trunk, you'd be wrong. An elephant's penis can be massive - in some cases, bigger than an entire human being. It can also move around like a trunk, which means it can wrap around objects and pick them up.see more on Elephant
Dolphins are incredibly smart animals, which may explain why they have minds about as filthy as humans'. Their penises are not only retractable, but also prehensile. That means they can use their shlongs to pick up objects. But mostly, dolphins use their penises to attempt to mate with anything and everything in sight. They've even been known to hump humans.

When you have both male and female sex organs, deciding who is going to have the babies can get pretty complicated. Luckily, the flatworm has developed a unique way of deciding who will be the mother: a sword fight. The mating process for the flatworm involves both parties trying to stab each other with their penises. The duel can last an hour, with multiple penis stabs for each party, but the minute one is successfully inseminated they both take on the requisite gender roles.see more on Flatworm
Duck penises are pretty crazy. They're shaped like corkscrews - the better to navigate female ducks' labyrinthine, dead-end filled vaginas. But the Argentine duck has another use for his penis. This species has an especially long penis, which scientists believe it uses to lasso and subdue females in order to mate with them. It's also covered in spikes, which helps keep them connected during sex.
