The Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
The word Rieppeleon is named after the scientist Olivier Rieppel.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
Trioceros schubotzi can be found at elevations as high as 4500m.
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.
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.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
Chameleons have a very poor sense of smell.
The word Chamaeleo is derived via Latin from the Greek word khamaileon. It roughly translates to ground lion. Khamai means on the ground and leon means lion.
The word Brookesia is named after the British naturalist Joshua Brookes.
