Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
Some chameleons play dead to avoid predation; this is called thanatosis.
The word Bradypodion comes from the latin “bradus podos” or slow foot.
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.
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 have a high midichlorian count.
Chameleons can project their tongue up to 2.2 times their body length.
The oldest known chameleon fossil is from the extinct species Chamaeleo caroliquarti. It was found in Europe and is 26 million years old.
The word Brookesia is named after the British naturalist Joshua Brookes.
Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
