Spectacular mass spawning occurs in the Spencer Gulf where thousands of Giant Cuttlefish congregate in relatively small patches of rocky reefs. reproduction in which eggs are released by the female; development of offspring occurs outside the mother's body. Bayesian spatial models can greatly enhance the utility of habitat analysis for conservation planning because they add the statistical flexibility necessary for analyzing regional survey data while retaining the interpretability of simpler models. (Karleskint, et al., 2013; Payne, 2010), After the egg capsules have been laid, the female cuttlefish abandons them and dies shortly after, so there is no further parental investment.

Non‐breeding, captive European cuttlefish Sepia officinalis survive for 54–68 days following starvation (Castro, Garrido & Sotelo 1992), so the actual breeding durations of male S. apama (40 days) are consistent with the higher metabolic rates of reproductive activities compared to metabolic rates of non‐breeding S. officinalis in captivity.
