Chameleons are able to lash out with their sticky tongues that extend more than twice their body lengths, and achieve incredible accelerations of 25490 m/s2 or 264 g, corresponding to peak power outputs of more than 14,000 W/kg, outperforming any other amniotes. Christopher V Anderson of Brown University in Rhode Island, US, has tracked the mechanism back to stretching elastic tissues, similar to the stretching of a bow. This energy can then be released rapidly – much more so than muscles could provide directly.
