Chameleons have the highest magnification (per size) of any vertebrate, [41] with the highest density of cones in the retina. [42] Like snakes, chameleons do not have an outer or a middle ear, so there is neither an ear-opening nor an eardrum. However, chameleons are not deaf: they can detect sound frequencies in the range of 200–600 Hz.
Camouflage is an exciting animal adaptation that allows many different types of animals to blend in with their surroundings. The chameleon is one of the most recognizable animals that camouflages ...
Veiled chameleons also have a hooded head. Their hooded head helps chameleons collect water. When a droplet collection is on top of a chameleon's hood, the droplet slides down from the hood into the chameleon's mouth. [29] Veiled chameleon's hood also aids in reproduction. Males have a pointer hood than females.
Many assume the color changes undergone by the chameleon are a result of its attempting to camouflage itself, when in reality the chameleon changes its color as a response to light and temperature stimuli and as an expression of its emotions (like chameleon body language). Often when caught for analysis, the chameleon may turn a dark color.
Some lizards make unusual use of their sense organs: chameleons can steer their eyes in different directions, sometimes providing non-overlapping fields of view, such as forwards and backwards at once. Lizards lack external ears, having instead a circular opening in which the tympanic membrane (eardrum) can be seen.
Smaller chameleons inhabit grasses while larger chameleons are found mainly in bushes and trees. This is territorial, because it is believed that larger males would cannibalize smaller ones intruding on their territory. An alternative thought is that the smaller chameleons simply do not have big enough limbs to grasp larger branches correctly.
Chameleons - Colour change signals a chameleon's physiological condition and intentions to other chameleons. [3] [4] Because chameleons are ectothermic, they change color also to regulate their body temperatures, either to a darker color to absorb light and heat to raise their temperature, or to a lighter color to reflect light and heat, thereby either stabilizing or lowering their body ...
Also like other chameleons, C. zeylanicus has bifurcated feet with a tongs-like shape, a prehensile tail, independent eye movement, and the ability to rapidly change skin colouring and patterns. Despite common misconceptions, they do not change their visual appearance based on their surroundings or background, or even for camouflage, and may ...
