Mike and a few other people have been on me for some time to post some of these videos. I've been incredibly busy and haven't had the time to figure out how to get them down to a reasonable size to post online before now. Each video is about 1.5 GB or more. After graduating from Cornell University I've moved down to Tampa, FL where I'm going to grad school, teaching Intro Bio 2 labs and doing research on the kinematics and morphological basis of ballistic tongue projection and protraction in chameleons at USF. Part of my research includes using high speed video cameras to film chameleon feeding events for analysis of performance, velocity, rate of energy release, etc. The videos I'm taking are at a rate of 3000 frames per second which enables me to get an incredible amount of detail.
The following video is subsampled from the full video file and played back at a slower frame rate such that it is now 20 times slower then real time. The original videos I analyze are much larger and have about 5x the number of frames than this subsampled video. I also have the ability to play it back at just about any rate of speed I wish and analyze them frame by frame. This video is of a male Rieppeleon brevicaudatus of 5.5 cm SVL projecting its tongue 9.95 cm. When you click the link, you'll want to click "Full Size" to the bottom left of the video window to view a larger (albeit still small) version of the video:
Click me - Brev01-03 video
Enjoy and hopefully as I get additional time, I'll be able to post more and slowed down more so you can see all the muscles move.
