Let’s talk claws. The Japanese spider crab’s claws are about 3 feet long. That’s not a pinch; that’s a guillotine.
Fossilized claws from Megaxantho show crushing surfaces the size of a fist. You don’t want that grabbing your ankle. Trust me.
One fossil claw from Japan, found in 2026, was nearly 4 feet long. That’s bigger than some kids. It belonged to a crab that lived 120 million years ago.
What would you do with it?
If you met one today, what would you even do? Scream? Take a selfie? Probably both. Then run.
These crabs aren’t aggressive to humans. They eat dead stuff on the ocean floor. So they’re more like underwater garbage trucks. But scary-looking ones.
Still, if you saw one in a dark alley, you’d nope right out of there. And I wouldn’t blame you.
