Let’s face it, guys: Having a penis is awesome. Whether it’s the benefits of urinating-while-standing or the sexual joys we all discover our dicks are capable of during our teenage years, that piece of multipurpose flesh between our legs often seems like our best friend.

We may be well aware of the many types of different dongs within the human race , most of us are probably equally unaware of the myriad forms the penis takes in the animal kingdom. Just as the beasts of this world differ from us in nearly every way imaginable, their units are equally as varied. Some are enormous; others diminutive. Some creatures can use their members in ways we’d never dream of. And some males don’t have penises at all. (We call those “the unfortunates.”) Here, a quick look at the literal birds and the bees—or at least, the odd masculine parts found between their legs. Or, in some cases…that actually are their legs.
