Chameleons have a high midichlorian count.
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 Calumma comes from the Latin word for covering. This genus consists of chameleons from Madagascar with occipital lobes.
The word Rhampholeon is taken from the Latinized Greek “rhamphos leon” meaning crawling lion.
Some chameleons play dead to avoid predation; this is called thanatosis.
Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
The chameleon tongue accelerates towards its target at over 1642m per second. Chameleons rarely miss their intended food item.
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.
Trioceros schubotzi can be found at elevations as high as 4500m.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
