True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
Chamaeleo namaquensis is found in the desert of Namibia. To cool off it will sometimes bury itself in the sand.
Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
Pygmy chameleons (Brookesia, Palleon, Rhampholeon and Rieppeleon sp.) often resemble dry leaves, mosses and branches.
Chameleons have a very poor sense of smell.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
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 acrodont teeth meaning they are an extension of the jawbone. They are not set in sockets nor are they replaced.
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!
Chameleons can project their tongue up to 2.2 times their body length.
