The list of unappetizing mating rituals is extensive, but today we’re going to limit ourselves. Many of the customs are, after all, just not appealing to humans. Male camels inflate a large sac in their mouths so that it hangs out the side, cover themselves in stinky pheromones, and foam at the mouth in order to attract a mate. We’re not here to judge lady camels (or, for that matter, any male camels who find that sexy). We’re here to talk about sex that’s bad within a species.
