• 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.

Depth: 5.0m + 4.1

Visibility: 0.5m + 2m 

It was a beautiful morning as we headed out to sea. The crew quickly put our vessel on anchor and the cage in the water. Our divers received their wetsuits and soon we waited for the sharks to arrive. While we waited, the marine biologist on board spoke about the various research projects Marine Dynamics and the Dyer Island Conservation Trust are involved in. Towards the end of the trip we went passed Dyer Island and Geyser Rock, so we could show our guests the Cape fur seals colony. Afterwards we headed back to shore, where our guests finished the trip with some nice soup and bread. They received a voucher so they can come back another day, hopefully see the sharks another time.
