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 small to medium-sized lizard, the green anole is a trunk-crown ecomorph and can change its color to several shades from brown to green. Other names include the Carolina anole, Carolina green anole, American anole, American green anole, North American green anole and red-throated anole.
Colour change in chameleons has functions in camouflage, but most commonly in social signaling and in reactions to temperature and other conditions. The relative importance of these functions varies with the circumstances, as well as the species. Colour change signals a chameleon's physiological condition and intentions to other chameleons.
The smooth helmeted iguana is a medium-sized lizard with long slim legs and very long toes. It can be grey, olive, brown, black or reddish-brown with irregular blotches. [6] The smooth helmeted iguana can change the color of its skin as a method of camouflage. As indicated by its name, the smooth helmeted iguana has a prominent crest on its ...
It can change color. The color pattern of spots and markings makes it well-camouflaged against the lichen-spotted tree bark on which it commonly resides. [8] The lizard prefers smaller branches and individuals have a small range, only venturing around a territory of no more than 6 meters for foraging and mating. [6]
The colors display the level of stress that they are under. It has been determined through experimentation with the lizard species that brighter colored stripes signify that they are under more stress. When the lizard is exposed to a stressor, the stripes on the lizards' body transition from a brown color to a pale blue or green. [9]
The ground-colour is generally a light brownish olive, but the lizard can change it to bright red, to black, and to a mixture of both. This change is sometimes confined to the head, at other times diffused over the whole body and tail.
Males of many species may aggressively defend territories when mating, but only rarely does this result in physical combat. Like many anole species, this lizard can change colour from dark brown to tan -this is in response to emotions, rather than a method of camouflaging itself such as true chameleons. [12]
