Chameleons can project their tongue up to 2.2 times their body length.
The process of shedding is called ecdysis.
Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
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 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.
The word Rieppeleon is named after the scientist Olivier Rieppel.
The word Brookesia is named after the British naturalist Joshua Brookes.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
Furcifer labordi (Labord’s Chameleon) has the shortest lifespan of only 4-5 months. It also has the shortest lifespan of any tetrapod!
