    These mantis shrimp has these two “clubs” for front arms. They use them to stun or bludgeon their pretty. They can move them so fast that they can create pockets of vacuum in the water that then rapidly collapse. I think it’s called cavitation. The collapsing bubble can even generate light.

    Don’t make a mantis shrimp in an aquarium angry, those appendages are strong enough to break glass.
