  • 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.

What an incredible day out on the water! We barely had to wait 5 minutes for the sharks to arrive on the scene! Our crew member, Warren, had his hands full when handling the bait line. One shark in particular was keeping him occupied in the way which it kept chasing after the bait. It was fantastic to watch the game of cat and mouse between the two! The sharks today were very jumpy and spent much of their time out of the water, great for some photo opportunities! Our largest shark today was a massive 4.1 meter gentle giant who came to inspect the boat and then went about his business. The trip out to Dyer Island afterwards gave everyone an appreciation for the beautiful and abundant biodiversity in the area, which is one of our main goals by doing these trips! Great day...
