Chameleons have a very poor sense of smell.
Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
The word Rieppeleon is named after the scientist Olivier Rieppel.
The word Brookesia is named after the British naturalist Joshua Brookes.
Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
Chameleons change color by rearranging a lattice of nanocrystals in one of their top layers of skin cells called iridophores. Chameleons can then stretch this layer, broadening the nanocrystalline lattice, thereby causing it to reflect a different wavelength of light.
The word Kinyongia is from the Swahili word for chameleons: Kinyonga.
Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
Furcifer oustaleti (Oustalet’s Chameleon) is the longest chameleon species reaching lengths of 27 inches (68cm).
Chameleons have laterally compressed bodies. This enables them to warm up quickly by presenting a larger surface area to the sun. It also helps some chameleon species blend in among the similarly shaped leaves in their environment.
