Their presence however, can be a signal for other things. At its largest, the head fish may measure as much as 11 feet in length and at times weigh as much as 2,000 pounds. Those found in the Gulf are typically only half that size. I've seen a few in the last couple of days. Not the most attractive of fish, even by fish standards, mola appear to have had their bodies bitten off just behind their fins, giving the impression of just a big floating fish head.
Molas are part of the oceanic sunfish family.
They swim slowly and usually near the surface. Their high dorsal fins stick out of the water, and they have at times been mistaken for sharks. Not to be feared, the mola are usually found in tropical and subtropical waters where they can be seen feeding on jellyfish. As a food-fish, they are of little value, yet sometimes oil is made from their livers. Maybe mola molas can't inspire fear as a sharks can, and maybe they're not particularly graceful or attractive.
