• Shark cage diving in Gansbaai, South Africa with Marine Dynamics. Experience the exceptional and come face to face with a great white shark! 

  • The exact world record white shark is a contested issue, but chances are it is between 6-7m. In Gansbaai, the largest white shark ever caught was at Danger Point and measured up to 5.9m.

  • If you see a white shark in the water don’t panic. Chances are high that the shark has already detected you and isn’t interested. White shark attacks are normally associated with poor visibility, so avoid murky conditions.

  • White sharks have a unique system called a “counter current heat exchange”, which keeps their body  tempreture +/- 7C above the surrounding water temperature. 

  • All sharks have an incredibly unique system on the tip of their nose called the “ampillae of Lorenzini”. These are small pores filled with a gel that transmits the electrical currents in the water to the shark’s brain so that it can assess its environment.

  • White sharks give birth to live young (not eggs), and they give birth to 6-8 pups at one time. Pups are usually between 1.0-1.5m in length and are born with teeth.

  • Body language has been a well documented form of shark communication and has identified body arching, jaw gaping, and other postures as specific social tactics.

Author: Oliver Jewell (Marine Biologist)
Born in London, England, Oliver has been in South Africa for the past 4 years after earning a BSc (hons) in Oceanography from the University of Southampton. His first experience with Great White Sharks was similar to many people's only experience - watching the film Jaws. Since that day, he has been dedicated to learning everything he could about sharks and ways of protecting them.


Guest Comment: Fantastic, loads of sharks and huge too. Leanne and Graham Eusha, from the UK

Water Temperature: 16.6 'C
Depth: 12m
Visibility: 1m
Number of Sharks: 9
Conditions: Calm, flat and clear!

The only worry with today’s trip was that the algal bloom which has been prominent in the bay may affect our visibility. Sea conditions were perfect with a slight breeze and no swell, unfortunately the bloom however remained and visibility was reduced. This had little to no effect on our trip as within five minuets the now giant ‘Woundy’ appeared. We’ve been seeing this shark since 2007 when she was less than 3 meters in length and have continued to be visted on and off for the past 5 years. She is now over 4 meters in length and completely dominated the first half of our trip. Rubbing alongside the cage as she passed and giving every person who entered the cage a jaw dropping, breathtaking experience. By the end of the trip many other sharks had arrived and we sighted at least 8 or 9 – possibly more. Fantastic stuff! Thank you very much to Paul Hubert of Paul Hubert Ltd (UK & Ireland) for adopting 2 white sharks, they will be tagged later this year.
