The Port Jackson shark, Heterodontus portjacksoni, reproduces through internal fertilisation. Initial embryonic development is internal with each embryo surrounded by an egg case. These capsules are then laid into the external environment where development continues until hatching. This is similar to the reproductive pattern of which mammals?
