Their hunting style is to sit and wait for their food to come to them. They also will pursue slower prey on the ground. Their feeding response is triggered by movement of prey. Because they swallow their prey whole there is little need for teeth. They also lack throat muscles to help them swallow, so they sort of push their food into their stomach with their upper head muscles and eyes.
Males move to the pond first and begin calling.
Usually, this activity takes place on rainy nights when the barometric pressure is falling. Once a female arrives, she selects her mate and breeding begins. When the male and female come close together, the male clasps the female around the waist with his forelegs. This clasping, known as amplexing, stimulates hormones in the female that cause her eggs to be released into the water. When this occurs, the male releases sperm, fertilizing the eggs.
