The word Calumma comes from the Latin word for covering. This genus consists of chameleons from Madagascar with occipital lobes.
Furcifer labordi (Labord’s Chameleon) has the shortest lifespan of only 4-5 months. It also has the shortest lifespan of any tetrapod!
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.
Chameleons have a very poor sense of smell.
Trioceros goetzei (Goetze’s Chameleon) emits an audible, high pitched whistle when threatened.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
The chameleon tongue accelerates towards its target at over 1642m per second. Chameleons rarely miss their intended food item.
