Panther chameleon tongue launch

A local park guide was holding dead crickets outside of this view to trigger this Panther Chameleon to attack by rocket-launching its tongue. Four photographers lined up and it took 3 tries for anyone to get a good shot, and that lucky person was me :)

And yes, it really was luck. Their tongues launch at 26 times their body length per second, accelerating from 0 to 20 feet per second (0 to six meters per second) in about 20 milliseconds.
