The oldest known chameleon fossil is from the extinct species Chamaeleo caroliquarti. It was found in Europe and is 26 million years old.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
Chameleons do have taste buds on their tongue but overall they have a poor sense of taste.
Furcifer oustaleti (Oustalet’s Chameleon) is the longest chameleon species reaching lengths of 27 inches (68cm).
Many chameleon species have a bright red, orange or yellow mouth. This conspicuous interior when displayed is used as a defense against predators.
Chameleons can project their tongue up to 2.2 times their body length.
Furcifer labordi (Labord’s Chameleon) has the shortest lifespan of only 4-5 months. It also has the shortest lifespan of any tetrapod!
The word Brookesia is named after the British naturalist Joshua Brookes.
