The males do not grasp the females' bodies but stand in front of the females, sometimes restraining them with one hind foot. In this position a male beats the tip of his tail, producing a current in the water that carries a scented chemical from glands in his swollen cloaca to the female's snout. Fertilization takes place inside the female's body. She lays the eggs in water, and the eggs attach to underwater plants.
