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]
This free downloadable lesson plan explores various species of animals that camouflage and dives deeper The chameleon is one of the most recognizable animals that camouflages itself, changing its ...
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.
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.
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 common misconception is that these chameleons use their color-changing abilities as camouflage, but they actually use their color-changing skin to court and show stress or emotion. Males are distinguished by a longer tail, more prominent dorsal crest, slimmer body type, and persistent patterning.
Different ambush predators use a variety of means to capture their prey, from the long sticky tongues of chameleons to the expanding mouths of frogfishes. Ambush predation is widely distributed in the animal kingdom, spanning some members of numerous groups such as the starfish , cephalopods , crustaceans , spiders , insects such as mantises ...
For example, cuttlefish and chameleons can rapidly change their appearance, both for camouflage and for signalling, as Aristotle first noted over 2000 years ago: [2] The octopus ... seeks its prey by so changing its colour as to render it like the colour of the stones adjacent to it; it does so also when alarmed. —
