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 ...
Reptiles tend to avoid confrontation through camouflage. Two major groups of reptile predators are birds and other reptiles, both of which have well-developed color vision. Thus the skins of many reptiles have cryptic coloration of plain or mottled gray, green, and brown to allow them to blend into the background of their natural environment. [135]
Squamata is the largest order of reptiles, comprising lizards, snakes and amphisbaenians (worm lizards), which are collectively known as squamates or scaled reptiles. With over 10,000 species, [15]
Reptiles are tetrapod animals in the class Reptilia, comprising today's turtles, crocodilians, snakes, amphisbaenians, lizards, tuatara, and their extinct relatives. The study of these traditional reptile orders , historically combined with that of modern amphibians , is called herpetology .
The study of the traditional reptile orders, customarily in combination with the study of modern amphibians, is called herpetology. Reptiles have been subject to several conflicting taxonomic definitions. In Linnaean taxonomy, reptiles are gathered together under the class Reptilia (/ r ɛ p ˈ t ɪ l i ə / rep-TIL-ee-ə), which
The order of the Anolis grahami is Squamata, which is a category that refers to scaled reptiles. Squamata is the most common order of reptile, and it includes species of snakes, lizards, and amphisbaenians. Species that are part of this order can be found all across the world, on every continent except Antarctica.
This group of lizards includes some more popularly known, such as the domesticated bearded dragon, Chinese water dragon, and Uromastyx species. One of the key distinguishing features of the agamids is their teeth, which are borne on the outer rim of their mouths ( acrodonts ), rather than on the inner side of their jaws ( pleurodonts ).
The major reptile group Diapsida, for example, is defined by the presence of two temporal fenestrae on each side of the skull. The infratemporal fenestra , also called the lateral temporal fenestra or lower temporal fenestra , is the lower of the two and is exposed primarily in lateral (side) view.
