  • 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: “Phenomenal experience! Great Day! Pod of dolphins still my favourite. Just like Galapagos!” Natalie Kennedy.

Today was so much more than just a shark cage diving experience, we were so fortunate to have loads of shark activity as well as various other animals in the area! Our day started brilliantly with lots of active sharks and amazing visibility. “Big Nemo” paid us a visit and she was looking very ravishing!  After our amazing shark diving excursion, our guests were welcomed by at least 20 bottlenose dolphins off the bow of the boat. They were truly an awesome sight. After that we ventured past shark alley to visit our friends the seals who were lazing about on Geyser Rock. Finally making our way back into port we had some subantarctic skua trying to grab some fish from our crew. It is amazing how these birds literally eat out of your hands. Truly a great day...
