  • 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: “The crew was incredible, we wish we could’ve seen more but that’s mother  nature!” Cassy and Ernie.

“Great experience, great crew! Thank you for everything!” Jenna and Danny.

“Fantastic watching the sharks swim past. Great experience!” James.

On our way out of the harbour we were lucky in that we spotted two Southern Right Whales. That is a great way to start a shark trip! The sharks were a bit reluctant to make their presence known and they gave some distant passes. Nonetheless they did show up to put on a show! We also had a frenzy of small bait fish known as mullet around the boat that seemed to enjoy our chum as much as the sharks did. As you can see from the photos there is always a lot to see in the area including the sharks! You never know what amazing things you may spot...
