Here's a funny thing about animal mating habits.
There was a kind of ancient shark called Falcatus falcatus that lived during the Devonian and Carboniferous periods. It's sometimes known as the Unicorn Shark due to the large horn-like structure that the male had just behind the head (actually a heavily modified fin).
Now, there's a hilarious reconstruction of the female biting the male's "horn" as part of a mating ritual, but it's just a cool drawing someone made to explain why only the male had the horn, right?
