Snakes live in nearly every habitat imaginable, from forests and lakeshores to prairies and deserts, and on every continent except Antarctica. In habitats like underground bur â¦ rows to the tops of trees, to ocean depths as much as 150 meters. Many snakes survive in regions that are extremely cold.
Oppositely to warm up their internal temperatures, snakes lie in the sun for long periods of the day, resting on large hot rocks so the conduction of the heat will increase body temperature and keep them warm during the day. Snakes are said to use behavioural adaptations to regulate their body heat. This explains why they choose to move into a cold or a hot location at different times depending on whether they need to be hotter or colder, the snake has no biological way of regulating temperature, therefore behavioural adjustments have to be made everyday.
