El majestuoso pez luna

We are the heaviest known bony fish in the world, look like a laterally flattened oval disc. One of our fascinating characteristics is that we don’t have a real tail or caudal fin, and our back end looks truncated. It is pretty normal if you find us floating on the surface of the water with one side up towards the sun. We are well-known as the ultimate sunbathers, and that is why we are called sunfish.
