• 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.

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.

It was an extremely eventful trip today with lots to see. We were being invaded by swarms of blue bottles (only 3) and they made an interesting conversation topic for quite some time! Our infamous “Big Nemo” made an appearance to the delight of the crew, she really isn’t the pretty’s girl in the water, but she’s still fantastic! All our sharks were more or less 3.5 meters in length today except for our final shark of the day who was 4 meters in length. The sharks were not us energetic and jumpy as usual, but they compensated by giving some REALLY close passes by the cage. On our way back to harbour we were treated with a bryde’s whale sighting, these ‘small’ whales frequent this area very often and it is always a treat to see them! A great day...
