The interesting things about worms is that they often have both male and female sexual organs, making them hermaphrodites. However, many species of worm can also reproduce asexually if need be. That’s right, they can get their own ‘tail’ so to say. Asexual worms that are born without genitals can be turned into sexual worms by feeding them sexual worms. Meaning that if they EAT worms with genitals for long enough, they will GROW their own genitals! It’s a screwing world for worms!

This is an interesting read if you’re into that kind of thing.
