SunFish

The sunfish is a very unique creature and one that you have probably never seen or heard of before unless youre particularly nerdy about your David Attenborough documentaries. Consider this: the sunfish is the heaviest bony fish in the world. This strange fish lives in tropical and temperate areas and it lives on a diet consisting mostly of jellyfish. It is also considered a delicacy among many Asian cultures, but the sale of sunfish flesh is forbidden in the European Union.
