Guess which mammal has the fastest muscles?

According to researchers, the muscles in a bat's larynx can contract up to 200 times per second during the "terminal buzz" as they make the final approach to a flying insect.

A side note, if you want to observe the effects of a terminal buzz, here is how to do it.  On a hot summer night, when moths are flying around outdoor lights, such as on the front porch, shake your car keys.  You should see any nearby moths immediately take evasive action.  Supposedly the jangling keys produce high frequency sound similar to the "terminal buzz" of a bat.

Superfast muscles are also in rattlesnake tails, songbirds, and the oyster toadfish which uses superfast muscles to generate a courtship whistle.
