Sheila Patek: The shrimp with a kick!

The video explores the fascinating world of mantis shrimp, focusing on their unique feeding strikes. It discusses the two types of mantis shrimp, spearers and smashers, and their incredible speed and force. High-speed video technology reveals the mechanics behind their strikes, including a catch mechanism and a saddle-shaped spring. The video also delves into the phenomenon of cavitation, which enhances their striking power. Finally, it touches on the visual signals used by mantis shrimp and acknowledges the contributions of collaborators.
