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

  • 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.

My initial love for the environment occurred at a young age when my father and I use to watch animal documentaries on Sunday evenings. I was hooked on anything ocean related when I saw these amazing submersibles going to such extreme depth in the ocean and discovering previously unseen things. To be the first to go somewhere where no one has been before was the first thing that attracted me to the field of natural sciences.

Guest comment: “Awesome fun! Way more calm and peaceful than expected. I will tell everyone back home to come see Marine Dynamics! Thank you for a fantastic time! :)” Jordan Hooper.

We absolutely love our coastline as well as the high nutrient levels which create our large food webs in the ocean. We have one of the strongest upwelling systems, off our coast, in the world. These factors contributes to the immense diversity in the ocean but it has one large drawback for shark cage diving, it decreases our visibility severely. We had nice big sharks today who were a bit more relaxed and not as active in going for the bait, it was still fantastic to see them make their slow passes. One of our regular sharks arrived on the scene today with fresh scars; it’s never a pleasant sight. The scars could have occurred as a result of several speculative factors, only a closer inspection would reveal the answer. We had an awesome bunch of guests on board who were in very high spirit. It was a pleasure having you on board. Great stuff...
