This shark has unique blood flow that circulates in opposite direction for an efficient transfer of metabolic heat.This allows for heat to exchange efficiently around the body in the brain, swimming muscles and stomach, so the Great White can go in waters too cold for other sharks. Reproduction for the Great White is like many other sharks, it generically uses internal fertilization to develop offspring. The mother carries the yolk like shelled eggs until body development is complete, this time period of her life is called ovoviviparity. After a year or longer he pups (baby sharks) are ready to be born in to the water. Right when the pups leave their parents they are forced to fend for themselves and live on their own. It can be said that it takes up to a whole year or longer for the mother to rebuild her energy before becoming a parent
