Chameleons Quick To Stick Out Their Tongues
Small chameleons have quicker tongues
Now Dr. Christopher Anderson from the Department of Ecology and Evolutionary Biology at Brown University in Rhode Island has studied smaller chameleons, ranging in length from 4 to 20 centimetres. The study concluded that small chameleons outperform their larger relatives in tongue speed and acceleration, and tongue length. Small chameleons stick their tongues out 2 1/2 times their body length and, in automotive terms, go from zero to 60mph in a hundredth of a second.
Because smaller species have greater metabolic needs, they have to be able to capture more prey, at a greater distance, in order to survive.
