What primary reproductive classification describes the great white shark, where eggs hatch internally and pups develop using nourishment from a yolk sac and uterine secretion?
Answer
Ovoviviparous
The great white shark utilizes an ovoviviparous reproductive strategy. This means that fertilization occurs internally, and the eggs develop inside the female's body; however, the primary nourishment for the developing embryos initially comes from the yolk sac contained within the egg. Following this phase, the developing pups switch to receiving nutrition via a uterine secretion produced by the mother. Finally, some pups may consume unfertilized eggs within the uterus. After a gestation period lasting about twelve months, the female gives live birth to a small litter, usually numbering between two and ten pups, which are immediately capable hunters measuring four to six feet long.
