Chameleons Lick Branches


When exposed to new environment, chameleons sometimes lick off branches. 

It is so rarely observed phenomenon that to take a photo of it is almost impossible, especially in the wild (here a wild male F. pardalis in Ambilobe, Madagascar)...

It seems this behavior serves the vomerolfaction, same as in other squamates despite of the fact the function of the vomeronasal organ is considered vestigial and is poorly studied in chameleons.
