  • 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.

Location: Joubertsdam
Water Temperature: 13.5'C
Depth: 9.5m
Visibility: 2m
Number of Sharks: 13
Conditions: Some fog at times.

We had a slow start to our trip today with only one shark for quite a while, the visibility was however amazing in the water. It was only after we had repositioned the boat did we receive a flurry of shark activity! The sharks were full of energy and put on quite a show for the clients. There was one 3.5 meter shark that was keeping our bait handlers on their toes. It was astonishing to see how quick such a large animal could move so effortlessly through the water! The fog allowed the sharks to have a more dramatic impact on the guests, giving them a more spooky appeal :)! The water was beautifully calm today and everyone had a great time! That always makes me happy...
