1. A single wingbeat of a honeybee 4.4 ms

   Bees beat their wings about 230 times per second — that frequency is exactly what produces their signature buzz.

   Small chameleons have the fastest tongues, accelerating at hundreds of g — proportionally the most powerful movement of any reptile, bird, or mammal.
