Chameleons do not have external ears or a tympanic membrane, but they do have internal ears as well as degenerated middle ears. They do not hear well but they can detect low frequency sounds.
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.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
Some chameleons play dead to avoid predation; this is called thanatosis.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
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.
Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
Chameleons have a very poor sense of smell.
The word Kinyongia is from the Swahili word for chameleons: Kinyonga.
