Packing a Punch
July 20, 2008 9:56 PM Subscribe
When you first hear of a shrimp breaking out of it's tank, the prospect isn't really frightening. But when you learn that the mantis shrimp has punched through the glass container, it becomes a little more serious.
Not only does the shrimp punch over 50mph, it also boils the water around the punch. UC Berkeley's high speed cameras couldn't even capture the movement, they had to get a little help from the BBC.

Oh, nice first post, btw!

I'm fairly sure I saw one of these on a trip in seventh grade. The instructor wasn't at all pleased with the punch he received ;)

Large smashers can even make meals of crabs, buckling their thick armour as easily as they do aquarium glass. And they are often seen beating up much larger fish and octopuses, which are unfortunate enough to wander past their burrows.
At the time of writing, the mantis shrimp's punch was a strong candidate for the fastest movement in the natural world. It has since been trumped by the bite of the well-named trapjaw ant, whose mandibles close with an almost unbelievable maximum speed of 140 mph.
Right, I'm off to engineer a trapdoor mantis shrimpantopus & take over the world.

I have gotten this close to a mantis shrimp in the wild. I knew about their awesome hyperspectral trinocular rotating compound eyes and their uber-cute larval stage, but the punching power is news to me. Maybe I shouldn't have shoved the lens in its face so closely.

Shit like this makes me exceedingly glad I'm human. Plenty of awful things could happen to me today, but the odds that something will tear my arm off and eat it in front of me before bludgeoning me to death are fairly slim.

Slow and steady wins the day, too. I had a fish that sucked up pebbles and blew them at the exact same spot on the tank every day for years until it finally broke the glass. I'm sure he felt that in science, a negative result is still a result.

Several of these pages claim that they strike with the force of a rifle bullet.
The video that clearly posted shows a crab still clearly alive, and ostensibly putting up a (futile and ineffective) show at fighting back, after literally two dozen punches.
I'm finding it hard to believe that that crab would be alive after two dozen rifle shots.

Mantis Shrimp Facts:
- There is no chin under the mantis shrimp’s head. There is only another fist.
- The mantis shrimp doesn't need a flashlight. When he wants to illuminate something, he just punches the water until it glows.

Actually, I may have eaten one of these. There was a whole spread of them in the buffet at the Holiday Inn in Guangzhou, China. Nobody had a clue what they were, so I just called them "bug shrimp."
As far as I could tell, they weren't cooked, but maybe they stay a dull gray/brown when cooked. I couldn't figure out how to eat mine, and I just ended up scooping a few tiny white bits out of the long "tail" section. Those bits were pretty tasty, though.

whatnotever: there isn't much meat in a mantis shrimp and, as you say, it's quite difficult to eat. It's actually easier to break them with crackers and 'suck' the tiny bits of meat out (as you would do with a crab arm) but the sharp edges on the shell mean is not really that easy anyway.
However, mantis shrimps add a lot of flavour to soups, bisques and risotto stock and that's why they can be found in most markets in Mediterranean countries.
After whatching all those videos, I'll have a lot more respect for mantis shrimps next time I add a couple of them to my fish stock.
