The males are in charge of finding the ideal place for the female to lay her eggs, which they will later fertilize.

After the 40 days that the incubation process lasts, the adults abandon the eggs leaving them to their own fate. This is why a very low percentage of the embryos survive. Of the 10,000 eggs that are usually laid by the female, only 4 or 5 may be able to reproduce.
