  • 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: “Fantastic! Sorry about the tears and thanks for your support! Yay I did it :)!” Neil and Kris.

Location: Dam
Water Temperature: 15.1 'C
Depth: 12.4m
Visibility: 5m
Number of Sharks: 10
Conditions: Light rains.

Despite the light rains which we had to endure at the start of our trip, the weather wasn’t too bad at all. The seas were calm and the winds were very mild, great conditions for a shark dive. Some of our younger divers were a bit reluctant at first to dive with such large animals, but I am very glad to say that our youngest client, Holly, did make it into the cage eventually! Well done to her and to all others who conquered their fears. “Prop scar shark” made an appearance at the very end when we were hoisting the cage out of the water. We had three sharks that were around the 4 meter mark and the fact that the visibility was good made it even better. An awesome day...
