  • 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: “Thank you for this incredible experience and for your hard work in protecting these beautiful animals! The staff was perfect and the food was great. It was the best way to spend my money in South Africa! Thank you.” Pamela Quintero.

Depth: 12.6m
Visibility: 2.5m
Number of Sharks: 11
Conditions: Cloudy with some chilly winds.

What a fantastic day! The visibility was the best that I have seen in ages, that in conjunction with amazing sharks is a winning combination. The sharks arrived very quickly today and we had the first clients in the water before you could say ‘shark’! We had eleven large sharks, with one shark in particular showing all his pearly whites all the time. It spent more time outside of the water than in it :)! The water temperature drop has not gone unnoticed by the guests, however after a couple of minutes one gets use to it! Beautiful sharks, great visibility and awesome people made today a great trip...
