12. Monarch Butterfly
You know how you can smell your boyfriend coming in the front door after he’s been to the gym? Well, the monarch butterfly has you beat. These beauties can smell their lovers up to eight miles away. It’s not certain whether they just have a great sense of smell, or they’re really, really stinky. Either way, it’s a smell they apparently find intoxicating, because they’ll fly that eight miles to meet up with their one true love.
