Chameleons have acrodont teeth meaning they are an extension of the jawbone. They are not set in sockets nor are they replaced.
Chameleons can project their tongue up to 2.2 times their body length.
Chameleons have a high midichlorian count.
There are currently 202 recognized chameleon species and 85 of them are found on the island of Madagascar.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
Chamaeleo namaquensis is found in the desert of Namibia. To cool off it will sometimes bury itself in the sand.
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.
Some chameleons play dead to avoid predation; this is called thanatosis.
The word Bradypodion comes from the latin “bradus podos” or slow foot.
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.
