• 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.

This afternoons trip picked up where the first left off ‘Bent Fin’ and ‘Notchy’ circling the cage as we arrived. Very, very big sharks on the trip and we saw at least 12 of them including ‘Sharkius Maximus’ ‘Big Nemo’ among others. It was a lovely group of guests on Slashfin today too, plenty of families on board and Margaret Holden who came aboard at the grand age of 89! We’re honoured to have you all with us and it was great to be able to share fantastic shark sightings with you.

Many thanks,
