This new research gives some new perspective on mobility of largest sharks. Basking sharks are on par with great whites in acceleration during these jumps. Apparently the energy restrictions aren't quite as great as I suspected, and this fact has some merit in respect to the Megalodon shark. That said, I think that the dynamic potential of cetaceans at sizes exceeding several tons still seems much greater than that of sharks..it's just that the difference may not be as dramatic as I imagined. youtu.be/DPdyU3jY8wQ

^ Nice link. It's actually been known for quite awhile that basking sharks breach, although I didn't know it was at comparable speeds to a great white. Still, I don't think there's much of a question that great whites live far more active lives than basking sharks. As for comparative agility, please see the shark bitten bones thread for several instances of juvenile and up to adult size mega-toothed sharks likely preying on up 3-4 meter dolphins. Given the likely agility and speed of the dolphin, this should give an indication that even megatooths much larger than great whites were themselves capable of explosive predatory interactions.

It is comparable to a megatooth shark but not as much as people may believe. Megatooth sharks had apparently high body temperatures possibly around 35-40 degrees Celsius meaning an active lifestyle as elosha said. I believe it is due to the significant effect of gigantothermy on the body increasing the temperature.
