How do cuttlefish reproduce?
Reproduction: Mating of the Flamboyant cuttlefish occurs face-to-face. The male uses his hectocotylus arm to transfer a sperm packet into the female where internal fertilization of the eggs take place. The white round eggs, later becoming clear as they develop, are laid one at a time in crevices and cracks to protect them from predation. There is no parental care given once the eggs hatch. Newly hatched cuttlefish are capable of color camouflage. Soon after all the eggs hatch the female dies.
