To be sure, nature’s full of impressive fish; but when’s the last time you saw Lionfish Week on the Discovery Channel? Saw a movie about a killer clownfish? Evolution has honed and shaped the Great White to be an amazingly skilled and efficient hunting machine. Do you know what eats Great Whites? Nothing but other Great Whites and humans (and we have to cheat).
- That giant shark from Mega Shark Vs Giant Octopus (the Megalodon)? He’s the Great White’s (extinct) brother.
- Researchers used to think Great Whites were stupid, because they’d bite the boat instead of the prey dangling a foot away. It turns out it’s not because they were dumb, but because Great Whites roll their eyes inside their head to protect them from thrashing prey.
- So how do they find their prey without seeing it? Do they miss a lot? No. They can sense electric fields generated by living creatures. They can detect a half a billionth of a volt. That means they can literally sense your heart beat. (That’s why they would attack the boats. The metal boats generated stronger electrical fields than the dead bait.)
- And they can also smell one drop of blood in 25 gallons of water.
- Up to 300 miniature saws line their mouths, which tear through their prey as the shark shakes its head back and forth.
- Speaking of teeth, their skin is literally made of smaller teeth, replicas of the ones in their mouth.
- They can fold their stomachs inside out to vomit up anything they decide they regret eating.
- Great Whites have been found measuring 20 feet long and weighing 5,000 lbs.
- They can swim up to 15 mph. Can you run a 4-minute mile?
There are other cool things about them too, but maybe that’s enough for now.
