At first, the male performed courtship display distant from his own burrow while feeding. Suddenly, he returned to the entrance of his burrow and changed his courting behavior to more conspicuous way, lifting the large chela high without feeding. Then, a female appeared and entered the male's burrow and he followed her. After this recording, he plugged the entrance. She should have copulated and extruded eggs in his burrow. He changed courting behavior probably because he had found the approaching female and tried to surely invite her into his burrow. There were many rivals around him.
