Chameleons have a high midichlorian count.
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.
Chameleons have acrodont teeth meaning they are an extension of the jawbone. They are not set in sockets nor are they replaced.
The word Bradypodion comes from the latin “bradus podos” or slow foot.
Chameleons can project their tongue up to 2.2 times their body length.
The word Brookesia is named after the British naturalist Joshua Brookes.
Furcifer labordi (Labord’s Chameleon) has the shortest lifespan of only 4-5 months. It also has the shortest lifespan of any tetrapod!
Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
Some chameleons play dead to avoid predation; this is called thanatosis.
The oldest known chameleon fossil is from the extinct species Chamaeleo caroliquarti. It was found in Europe and is 26 million years old.
