However, snakes do not regulate internally the temperature of their blood. Called cold-blooded, snakes actually have blood that is responsive to the varying temperature of the immediate environment. Snakes can regulate blood temperature by moving. Too long in direct sunlight, the snakes' blood is heated by beyond tolerance.
The skull of Python reticulatus.. The skull of a snake is a very complex structure, with numerous joints to allow the snake to swallow prey far larger than its head.. The typical snake skull has a solidly ossified braincase, with the separate frontal bones and the united parietal bones extending downward to the basisphenoid, which is large and extends forward into a rostrum extending to the ...
Forked tongues have evolved in these squamate reptiles (lizards and snakes) for various purposes. The advantage to having a forked tongue is that more surface area is available for the chemicals to contact and the potential for tropotaxis. [5] The tongue is flicked out of the mouth regularly to sample the chemical environment.
The part of the body beyond the cloacal scale is considered to be the tail. [13] Sometimes snakes have enlarged scales, either single or paired, under the tail; these are called subcaudals or urosteges. [22] These subcaudals may be smooth or keeled as in Bitis arietans somalica.
The hemipenis is the intromittent organ of Squamata, [4] which is the second largest order of vertebrates with over 9,000 species distributed around the world. They differ from the intromittent organs of most other amniotes such as mammals, archosaurs and turtles that have a single genital tubercle, as squamates have the paired genitalia remaining separate.

Rat Snake. Adult rat snakes are typically 3 to 5 feet, but can get up to 6 feet long, according to experts with the Savannah River Ecology Laboratory.. Adult rat snakes primarily eat mice, rats ...
Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads (cranial kinesis). To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung.
