2009.009 . Tongue Action
Chameleon snaring some food with a swift tongue thrust. (Cropped using Picasa 3.0)
The muscles in a chameleon's tongue are unusually efficient at thrusting it out to great lengths very quickly. (Note to self: next time use Aperture priority setting and set it wide open with the f/1.8 lens. This one settled in at 1/100th of a second at f/6.3 with my 28-mm f/2.8 lens, way too slow for this chameleon.) Studying the structure and mechanics of these muscles could lead to advances in technology of propulsion, movement, or even the shutters on SLR cameras. This is called "biomimickry."
