Snakes breathe principally by contracting muscles between their ribs. Unlike mammals, they lack a diaphragm, the large smooth muscle responsible for inspiration and expiration between the chest and abdomen. Inspiration is an active process (muscles contract), whereas expiration is passive (muscles relax).
Ecotherms use the external environment to maintain their internal environment. If a snake, being an ecotherm needs to cool itself down it may take water from lakes and rivers. It may also use cool ground or the cool water to rest in allowing the conduction of the cooler surface to cool them down.
