The reaction to this kind of photo is always the same: “So what? The diver is probably like 100 feet away, and the fish is about to lick the camera lens. So how big is that fish really?”
Well, the mola mola, or ocean sunfish, is the heaviest fish in the world. The freakishly huge sunfish gets its name from the fact that it spends its time “sunbathing” at the surface of the water, in part to invite birds to fly down and gorge themselves on the skin parasites that infest it.
They are apparently harmless to humans, which is a good thing, because as you can see, your whole torso would fit into its mouth.
Actually, the sunfish is the heaviest bony fish. The whale shark is the largest fist in the ocean. The mola mola can get up to 14’ long though and weigh up to 2 tons.
