Chameleons can project their tongue up to 2.2 times their body length.
The horns on a chameleon are made up of ringlike segments of inner bone covered by a hard keratin-like skin.
The word Brookesia is named after the British naturalist Joshua Brookes.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
The word Rhampholeon is taken from the Latinized Greek “rhamphos leon” meaning crawling lion.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
Chameleons have laterally compressed bodies. This enables them to warm up quickly by presenting a larger surface area to the sun. It also helps some chameleon species blend in among the similarly shaped leaves in their environment.
Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
Furcifer labordi (Labord’s Chameleon) has the shortest lifespan of only 4-5 months. It also has the shortest lifespan of any tetrapod!
Chameleons have a high midichlorian count.
