  • 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: “Amazing, staff very helpful and good viewing in and out of the cage!” Zoe.

“Thank you for such an amazing day-it was so special to be able to watch such stunning animals up close!” Deb.

“Fantastic! Crew is top notch! Volunteers took excellent care of us!” Tisha and Jose.

Location: Dam
Water Temperature: 16.0 'C
Depth: 9.7m
Visibility: 4m
Number of Sharks: 9
Conditions: Sunny and windy.

The water temperature is warmer than it has been in quite a while; this made it easier for everyone in the cage. Our first shark today was an acoustically tagged shark and it was big, around the 4 meter margin. This shark was followed by several smaller individuals and it was at this time that a Cape Fur seal took a chance to make an appearance! I would be lying if I said that everyone on board wasn’t hoping to see some action take place :)! It was very special to see how the seal chased the fish and the sharks on their turn chased the seal and so the circle of life continues. All in one trip, awesome...
