Pygmy chameleons are sometimes referred to as False Chameleons. This term is actually incorrect and is in reference to anoles, particularly the Cuban False Anole.
The word Rieppeleon is named after the scientist Olivier Rieppel.
Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
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.
The oldest known chameleon fossil is from the extinct species Chamaeleo caroliquarti. It was found in Europe and is 26 million years old.
Some chameleons play dead to avoid predation; this is called thanatosis.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
The process of shedding is called ecdysis.
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!
Furcifer labordi (Labord’s Chameleon) has the shortest lifespan of only 4-5 months. It also has the shortest lifespan of any tetrapod!
