An active snake that moves around does not depend merely on vision. There are species of snakes that have the capacity to detect thermal radiation and thus be aware of any temperature changes in the surrounding areas. Heat becomes information for them. It has been proven that some snakes sensitive to infrared can distinguish very slight temperature fluctuations, creating spots in the environment that would be different than others despite being visually invisible.
However, it does not mean that the snake is seeking a spot in the literal meaning of the word. What happens is that the snake responds to a thermal environment that has some spots of temperature difference. A warmer area, a sheltered place, or temperature stability may become relevant in terms of biological information.
How Does Temperature Affect Hiding Behavior?
Scientific evidence indicates that snakes react to thermal differentials rather than temperature itself. In other words, a warm surface in a cooler surrounding will have more effect than an equally warm surface within a warmer environment. Thermal differential thus explains why some areas end up being favorite hiding places for snakes. Behavioral experiments conducted on snakes indicate that thermal gradient is among the factors considered when positioning their bodies while looking for resting places or ambush areas. Nevertheless, thermal gradient cannot be the sole consideration when selecting a place. Ecological considerations point out that apart from temperature, safety, moisture, and shade are also accounted for when deciding on hiding places.

Indoor Spaces Can Become Suitable Refuges
In indoor settings, microclimates are common, which are zones with relatively stable temperatures compared to adjacent areas. These can occur in wall cavities, basements, or disorganized corners. Scientific evidence on the choice of habitats by snakes proves that thermal refuges are useful in thermoregulation and thus become desirable temporary shelters. Nonetheless, having an area with stable or warm temperatures does not mean there is a snake. Instead, it signifies that the zone would be suitable for the snake. Science calls for caution in interpreting the findings. The variation in temperatures may point to an area with a high probability of a snake, but it is not conclusive proof of its presence. This is important in explaining behavior. An ideal hiding place is not only warm. It is part of an ecosystem that satisfies various biological requirements.
