Semysmauchenius sp1, ventral view

This Semysmauchenius spider can make a strike with its chelicerae in just 0.56 milliseconds. The spider was recorded at 3,000 frames per second (fps), but the video is playing at 20 fps, so in real life its movements would be 150 times as fast as seen here. (0:07)
