Males croak and call to attract females. When their eggs are mature, the females enter the water and are clasped by the males in the process called amplexus. As the female lays the eggs, the male discharges seminal fluid containing sperm over the eggs to fertilize them. After fertilization, the jelly layers absorb water and swell.
