Living habits

Activity characteristics

The snake is a kind of temperature-changing animal whose body temperature changes with the temperature, because the snake itself has no perfect temperature regulation mechanism to generate and maintain a constant body temperature. The optimum temperature for snake activity is 20-30℃. In this suitable range, the growth rate of snakes increases linearly with the increase of temperature. Air humidity also has a great influence on snakes, generally 50-70% is appropriate.

The activities of snakes are closely related to the external temperature, humidity, light and food. Under the influence of these external environmental conditions, there are obvious seasonal and daily changes.
