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]
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 ...
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 ...
A chameleon's tongue striking ballistically at food. Chameleons (family Chamaeleonidae) are highly adapted as ambush predators. [38] They can change colour to match their surroundings and often climb through trees with a swaying motion, probably to mimic the movement of the leaves and branches they are surrounded by. [38]
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.
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.
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.
