Midair slug coitus

Did you know that leopard slugs practice aerial mating? Here's an illustrated slug kama-sutra, showing the process in depth.

So this is how they end up – the slugs hanging by a metre of slime, with their sexual organs entwined in this strange embrace. I suppose that they were exchanging some intimate substance. They stayed like this for a while, and unfortunately I was called away for dinner. When I returned they were gone, having taken their bungee cord with them.
