Thermographic image: a cold-blooded snake is shown eating a warm-blooded mouse. Warm-blooded is a term referring to animal species whose bodies maintain a temperature higher than that of their environment. In particular, homeothermic species (including birds and mammals) maintain a stable body temperature by regulating metabolic processes.
The cardiovascular system of snakes is unique for the presence of a renal portal system in which the blood from the snake's tail passes through the kidneys before returning to the heart. [79] The circulatory system of a snake is basically like those of any other vertebrae. However, snakes do not regulate internally the temperature of their blood.
Blind or blindfolded rattlesnakes can strike prey accurately in the complete absence of visible light, [13] [14] though it does not appear that they assess prey animals based on their body temperature. [15] In addition, snakes may deliberately choose ambush sites that facilitate infrared detection of prey.
Male Canadian garter snakes huddle around a female after hibernation when mating.. Huddling confers higher and more constant body temperatures than solitary resting. [3] Some species of ectotherms including lizards [4] and snakes, such as boa constrictors [5] and tiger snakes, [6] increase their effective mass by clustering tightly together.

Environments with unpredictable temperature changes might have favored animals that could regulate their body temperature internally, allowing them to adapt to varying conditions. Coevolution with Microorganisms: Homeothermy might have evolved in response to interactions with microorganisms, such as parasites and pathogens. Warm-blooded animals ...
