Snakes, like other reptiles, are cold-blooded and rely on external sources of heat to regulate their body temperature. However, when it comes to light and darkness, their preference varies depending on the species and their natural habitat. Some snakes are diurnal and thrive in open areas with plenty of sunlight, while others are nocturnal and prefer to hunt and move around in darkness. Additionally, certain species of snakes may prefer dim light or shaded areas over bright sunlight. Understanding a snake’s natural habitat and behavior can help in providing appropriate lighting and temperature conditions for pet snakes in captivity.
