Amphibians like this frog must stay near the water to live because their eggs can only survive in a wet environment. Buccal pumping is "breathing with one's cheeks": a method of ventilation used in respiration in which the animal moves the floor of its mouth in a rhythmic manner that is externally apparent. It is the sole means of inflating the lungs in amphibians.
