Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
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.
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 word Rieppeleon is named after the scientist Olivier Rieppel.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
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.
Chameleons have a very poor sense of smell.
