The smallest chameleon species is Brookesia micra with an adult length just over 1 inch (29mm). It hatches from an egg no bigger than a grain of rice!
The process of shedding is called ecdysis.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
The word Rieppeleon is named after the scientist Olivier Rieppel.
Chameleons have a high midichlorian count.
Some chameleons play dead to avoid predation; this is called thanatosis.
Chameleons can project their tongue up to 2.2 times their body length.
The word Calumma comes from the Latin word for covering. This genus consists of chameleons from Madagascar with occipital lobes.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
