Snipefish (Macroramphosus scolopax), like their seahorse relatives, employ a spring mechanism for feeding, according to research published yesterday (July 4) in Proceedings of the Royal Society B: Biological Sciences. The fish speedily rotate their trumpet-like snouts using stored elastic energy and suck prey into their distended mouths in 2 ms. The researchers used high-speed videos that were slowed down to observe the feeding strike motion.
