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.
Furcifer oustaleti (Oustalet’s Chameleon) is the longest chameleon species reaching lengths of 27 inches (68cm).
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!
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
Chameleons can project their tongue up to 2.2 times their body length.
The word Kinyongia is from the Swahili word for chameleons: Kinyonga.
Furcifer labordi (Labord’s Chameleon) has the shortest lifespan of only 4-5 months. It also has the shortest lifespan of any tetrapod!
Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
There are currently 202 recognized chameleon species and 85 of them are found on the island of Madagascar.
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.
