Furcifer oustaleti (Oustalet’s Chameleon) is the longest chameleon species reaching lengths of 27 inches (68cm).
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
There are currently 202 recognized chameleon species and 85 of them are found on the island of Madagascar.
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 very poor sense of smell.
Kinyongia uthmoelleri and Trioceros quadricornis gracilor have red claws.
The word Brookesia is named after the British naturalist Joshua Brookes.
The word Kinyongia is from the Swahili word for chameleons: Kinyonga.
Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
