•Reproduction: Female Great Whites give birth to between 2 and 10 live young at a time (pups), ranging from 1.1 to 1.65 m in length, after a gestation period of around 14 to 18 months.
•Body temperature: Great White Sharks have a counter-current heat exchange system that enables it to keep vital organs up to 14°C warmer than the surrounding water.
•Swimming speed: During ocean crossings, Great Whites keep a minimum sustained speed of around 4.7 km per hour, but they are capable of reaching speeds of up to 50 km per hour in short bursts.

•Hunting: During the winter seasons off the coast of Cape Town, in the False Bay area specifically, the White Shark will breach the water from the depths in its pursuit of prey, as a hunting technique, which has fascinated people the world over.
•Threats: Being perceived as the “apex predator” of the ocean, one would be excused in thinking that this creature has no threats; where in fact it faces two very real threats; 1. Humans and 2. Orcas or killer whales
•Defence: Great White Sharks will produce a pheromone that they release into the water, when they feel threatened or are killed, this pheromone is very distinct and pungent to other Great Whites and it basically tells them to “vacate the area”, which they will do, and sometimes as far as 160km for up to 10 to 12 weeks at a time.
•The Most Famous Great White Sharks: Deep Blue, the 7.3 meter female caught on camera off Guadeloupe. Colossus, the shy 5.5 meter bull (male), a regular visitor to False Bay’s Seal Island and finally Lucy, a 5.1 meter female who also calls Guadeloupe home.
