Film collections illustrating the early development of the ovoviviparous Lemon Shark and Sand Tiger Shark. These do not lay eggs into the sea like the dogfish but have the eggs hatch and develop within the mother’s womb.
Special effects shots of a model of developmental stages of the Lemon Shark and the Sand Tiger Shark. These demonstrate the yolk sac in the very young Lemon Shark and the cannibalism that takes place amongst Tiger Shark embryos around five months into development.
