Well, besides mermaids. I'm talking about Dunkleosteus terrelli, "a prehistoric sea monster [with] the most powerful bite of any creature yet known: up to 80,000 pounds per square inch." Nice. Very nice.
Philip Anderson of the University of Chicago -- who led the study -- says the creature -- which grew to 33 feet in length and weighed as much as four tons -- was also capable of opening its mouth in just 0.02 second. That would have created suction capable of drawing prey into its mouth.
Large prey, I'm sure. Beautiful.
I once read an account of a pod of orcas moving into the great white shark feeding grounds off the Farallons, and before driving them off for the season, caught a large great white, killed it, and tossed it around playfully for a while, blood everywhere, gigantic sharks scattering in fear. Killer whales. What fun!
I imagine Dunkleosteus made quite a mess when he ate…on the other hand, if he could open his mouth in .02 seconds with enough suction to draw the prey entirely in its mouth, perhaps he was an elegant eater. There's something even scarier about that.
