  • 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.

Today was a unique and interesting day on the water! We were joined exclusively by the national junior Dutch cricket team and their guardians! They were all very excited about the prospect of seeing great white sharks in the wild. The sharks however kept us waiting a bit longer than usual today, it was only after persuading the boys to sing to the sharks that they decided to make an appearance. We had another large 4 meter shark around the boat all to ourselves, due to the fact that we were the only vessel out on the water today! Our tailor made boat makes it much easier to endure large swells on the water. Some of our guests suffered from temporary “motion distress”, but that did not prevent them from entering the cage! Great stuff Holland...
