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. [43] Chameleons can see in both visible and ultraviolet light. [44]
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.
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 ...
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.
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 ...
Cott describes leaf-like fish, chameleons, and insects, and other mimetic forms of camouflage. A liana-like snake near Para (a haunt of Henry Walter Bates in Naturalist on the River Amazons) 160 times as long as it was thick is called "a revelation in the art of aggressive resemblance". Chapter 2.
Elephants have massive ears to help regulate their body temperature. They have huge blood vessels in their ears. The blood vessels are large and quite visible on the backs of the elephant’s ears.
