Life cycle and mating behavior
Maturità | Riproduzione | Deposizione | Uova | Fecundity | Larve
External fertilization with internal insemination (Ref. 101419). This is also called 'internal gametic association' which describes another unique phenomenon of the reproductive process. In this phenomenon, the presence of the spermatozoa in the ovarian cavity is done through copulation, but the spermatozoa entry into the egg and subsequent fertilization only occurred externally when the eggs are spawned and came into contact with seawater (Ref. 101419).
