Explanation
Snakes have several behavioural adaptations that help them to survive in hot and dry places. One behaviour that a snake does is to make their head appear larger by spreading it apart. They will also roll over on their back to appear to have a seizure/convulsion to scare away predators. To survive in hot/dry places such as the desert, a snake will use thermoregulation. They do this by laying in the sun at optimal times such as late afternoon, midday, and sometimes early morning. This helps them to avoid the extreme temps. Many snakes can also make themselves blend into the environment around them and look like the surrounding landscape. Snakes have also evolved so that they won't need much hydration in the desert. They will get the water they need from the prey they eat.
