Mantis Shrimp Punch at 40,000 fps! - Cavitation Physics

Meet a tiny shrimp that packs quite a wallop! Get to know the mantis shrimp and the amazing one-two punch it delivers to prey with a video from an engaging physics playlist. Junior biologists examine fun shrimp facts, such as why it has adapted to have the punching behavior, what organisms it preys upon, and how cavitation increases the shrimp's odds of scoring a meal.
