Robotic Spy Crab Takes Punch From Mantis Shrimp, Keeps Spying

With over 17 years of writing experience, Jonathan has had a passion for all things tech-related, ever since watching Inspector Gadget as a child. He's disassembled countless appliances and managed to put a few back together, and one still works. When not writing, he can often be found playing video games or accidentally hurting himself in the garage.

Created by John Downer Productions to observe sea life up close and personal, this spy camera was built to resemble a large crab so it can move about its quarry without the potential disturbance a sizeable underwater camera might cause. In the video, it wanders too close to a female peacock mantis shrimp’s den and gets punched in the claw. Thankfully, the well-constructed spy crab is able to withstand the attack.

The mantis shrimp has the world’s most powerful punch, traveling faster than a fired bullet. The punch is so fast that it causes cavitation bubbles (formed when the static pressure of a liquid reduces to below the liquid’s vapor pressure, leading to the formation of small vapor-filled cavities in the liquid) that ultra-briefly reach temperatures of 4,400°C. Mother Nature, isn’t she wild? And maybe even a little TOO wild as far as under-the-sea creatures go. I’m looking at you, deep sea octopuses!

Would I want to get punched by a mantis shrimp? Absolutely not. I also don’t want to be pinched by a crab or bitten by a shark. Truthfully, there are very few interactions I would like to have with sea life now that I think about it. However, I did kiss a stingray on vacation after being told it would bring good luck. I’ll be honest, though — I don’t think it’s working.
