  • 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: “Dude! That was amazing. Being face to face with this majestic animal was a once in a lifetime experience. The crew was really awesome!” Turkish Boyz.

It is absolutely fantastic if you have the sharks waiting for you on the water when you arrive! If every trip starts off like today I will be needing a larger memory card for my camera. We had fantastic weather today and even better sharks. Our old friend “chopper” made an appearance today and he seems to be getting bigger every time I see him! It is truly incredible at what rate these animals can heal from a serious injury. Even though one can still see the scars on the animal, it is much less prominent than before. We had very enthusiastic guests on board; they were keen to stay in the cage until tomorrow! Sorry guys, we only offer that package over the weekends :)! Awesome time...
