During maturation, there is a shift of emphasis from somatic growth to gonadal development and
vitellogenesis. Research observations suggest that energy and nutrients for maturation are supplied mainly by
diet rather than stored resources: the species does not use protein from muscle tissue for developing and
growing its reproductive tissues. Sepia pharaonis appears to be an intermittent multiple spawner. In captive
animals, the life cycle is less than 10 months. Estimated growth rates for wild animals show higher values for
females than for males
