Facts on the Great White Shark

The Great White Shark is one of the most fascinating and feared animals on this planet. Watching it breach - thrusting itself completely airborne out of the water with a twitch of the tail when taking its prey - is an awesome and quite terrifying sight!

Like so many other animals, the Great White is thoroughly misunderstood. This explains why it was threatened with extinction - helped in no small measure by the "Jaws" movie and trophy hunting. South Africa was the first country to protect the Great White Shark and is now the leader in Eco-Tourism with on average over 100 people a day traveling to Gansbaai and Cape Town to gain firsthand experience of these magnificent creatures. It's wonderful to know that their numbers are steadily increasing. 

It's pretty certain that sharks are not man-eaters, but rather are on the cautious side when faced with an unknown object, and will take an exploratory bite to see what it's all about. Unfortunately, their strong teeth and jaws make such a "bite" rather lethal. In most cases where Great Whites attacked people, only one bite was taken ... not exactly the modus operandi of a "human eating machine"!

A Great White must swim so that it can breathe, keeping its mouths open so that the oxygen-rich water flows across its gills.

A dentist's nightmare ... The Great White Shark has rows of replacement teeth. As older teeth snap off new ones develop in their place. They are triangular in shape with serrated edges for cutting.

Great Whites are very curious, and like whales will pop their heads out of the water to "take a look" - also called spy-hopping. No other shark does that. 



The best time to come see them?  April to September, because the water is warmer - despite it being winter (15-20 degrees celsius). This is also the time when the islands are full of female seals and their pups, the latter still learning to swim. Drowned pups are easy pickings for the Great Whites.

How do they catch the adult seals? Although the sharks are agile, so are the seals. The Great Whites have learnt that the best way to achieve success is by attacking from below - when the colour of their backs provides a perfect camouflage with the bottom of the sea. It's a vertical launch which takes the seals by surprise - the breach we have all seen on TV. Out comes the Great White - and if all went according to plan there's a little snack in its jaws ...

Great White Sharks have rigid fins and cannot stop suddenly - neither can they swim backward. They have no bones in their bodies which are made up of cartilage, making them extremely flexible.

Great Whites can go for days without a meal, but consume about ten tons of meat a year.

They are able to detect tiny concentrations of elements (such as blood) becaue of their acute sense of smell, enabling them to home in on prey by turning into the current.

Quick Facts on Great White Sharks
  • It's the largest predatory fish
  • They can can grow to a length of 7 meters
  • They weigh up to, and sometimes more than, 3 metric tons.
  • Great Whites are  highly adaptable - both in terms of temperatures and type of prey
  • They are intelligent, but cannot be trained by humans
  • The white shark is predominately an inshore predator.
  • Great White Sharks are normally found in areas where the water temperature ranges 10 - 20 degree C. Irrespective of water temperature, it regulates its body temperature at a constant 25 degrees celsius
  • It has highly developed senses and easily detect water movement, pressure changes and the lightest of electrical voltages
  • The Great White travels enormously long distances - up to 20 000 kn has been recorded in less than a year
  • It will prey on anything its own size or smaller, and is an accomplished scavenger
  • Its jaw is not fully attached to its skull and is highly flexible
  • The dorsal fin is flexible and is an integral part of its overall maneuverability.
  • IT IS THE WORLD'S MOST EFFICIENT KILLER

The Great White Shark is an animal that inspires awe and fear: it is one of the world's foremost predators, equipped with the most formidable jaws in the animal kingdom. With attacks seemingly on the increase in the Western Cape region, as well as the increased popularity of Great White Shark tourism and cage diving, this giant of the deep is often in the news, but frequently for the wrong reasons. "South Africa's Great White Shark" is the definitive text for cage divers, marine biologists, tour guides, and photographers, providing in-depth coverage of Great White behaviour, ecology, conservation, ecotourism and the truth behind cage diving, chumming and shark 'attacks'.
