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 Rhampholeon is taken from the Latinized Greek “rhamphos leon” meaning crawling lion.
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.
True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
Some chameleons play dead to avoid predation; this is called thanatosis.
Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
Chameleons can project their tongue up to 2.2 times their body length.
Furcifer labordi (Labord’s Chameleon) has the shortest lifespan of only 4-5 months. It also has the shortest lifespan of any tetrapod!
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 word Brookesia is named after the British naturalist Joshua Brookes.
