Tell us something you've seen in moves that you think might be scientifically inaccurate. In the "documentary" film Kung Pow the main character has a tongue which has its own pair of eyes and its own tongue. Well small fish can actually come a lot closer to that then you might think. The eyes are really on their tongue. They belong to a parasite. Cymotha are parasites that replace the tongues of their hosts with their bodies. And to add to the nightmare fuel, these parasites don't need their own tongues, because they drink blood directly from their host's tongue, or what's left of it. Having a parasite for a tongue can be just a nuisance for some fish, but for others, it can be , you know, harmful to their health. Now, you do not have to be worry about this happening to you. Cymothoa gets close to their hosts by resembling their food, which you probably don't eat, and they enter the fishe's mouths through their gills, which you probably don't have. But anyway... sweet dreams!
