Description of life cycle and mating behavior The male chooses a nesting site under a rock or ledge. Spawning males are territorial toward other males (Ref. 27547). He attracts a female into the nesting site and after more courting the female deposits her adhesive eggs. The female is then driven out and the male guards the eggs until hatching occurs. The nest usually contains eggs from several females (Ref. 27547). The male has also been observed to guard the young (Ref. 1998).
