Chameleons can project their tongue up to 2.2 times their body length.
Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
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.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
Chameleons have acrodont teeth meaning they are an extension of the jawbone. They are not set in sockets nor are they replaced.
The process of shedding is called ecdysis.
Some chameleons play dead to avoid predation; this is called thanatosis.
Pygmy chameleons are sometimes referred to as False Chameleons. This term is actually incorrect and is in reference to anoles, particularly the Cuban False Anole.
Chameleons have a very poor sense of smell.
