Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
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!
Trioceros schubotzi can be found at elevations as high as 4500m.
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.
Chamaeleo namaquensis is found in the desert of Namibia. To cool off it will sometimes bury itself in the sand.
The process of shedding is called ecdysis.
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.
Chameleons can project their tongue up to 2.2 times their body length.
