Chameleons are able to capture very large preys by projecting the tongue andretracting it once it is in contact with preys. A strong adhesion between thetongue tip and the prey is therefore required during the retraction phase toensure a successful capture. To determine the mechanism responsible for thisstrong bond, the viscosity of the mucus produced at the chameleon's tongue padis measured by using the viscous drag exerted on rolling beads by a thin layerof mucus. The viscosity of this secretion is found to be about 400 times largerthan the one of human saliva. With a dynamical model for viscous adhesiondescribing the motion of the compliant tongue and of the prey during theretraction phase, the evolution of the maximum prey size with respect to thechameleon body length is derived. This evolution is successfully compared within vivo observations for various chameleon species and shows that the size ofthe captured preys is not limited by viscous adhesion thanks to the high mucusviscosity and the large contact area between the prey and the tongue.
