• 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.

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.

 Location: Joubertsdam
 Water Temperature: 15.9'C
 Depth: 12.5m
 Visibility: <2m
 Number of Sharks: 11-12
 Conditions: Swells with poor visibility

It's a common problem during summer that we struggle with visibility and unfortunately today was one of those days. Sharks however were absolutely stunning in every sense of the word. Even though the crew are working with these animals everyday you could see it in all our faces - this was a special day. The star of the show was a large female close to 4 meters in length one of our guests wanted to call 'Sharkias Maximus' and the name suited her quite well. She dominated the other sharks around the boat rubbing along side the cage as she passed and then rushing the bait from below. We sighted 12 sharks in total with a size range of just under 4 to just over 2.

Comment: "Great Operation, crew, boat, facility all top notch. You made a great day even if the visibility wasn't great. Thanks." Blain Garrity from New Orleans
