  • 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.

Author: Oliver Jewell (Marine Biologist)
Born in London, England, Oliver has been in South Africa for the past 4 years after earning a BSc (hons) in Oceanography from the University of Southampton. His first experience with Great White Sharks was similar to many people's only experience - watching the film Jaws. Since that day, he has been dedicated to learning everything he could about sharks and ways of protecting them.

Location: Joubertsdam
SST: 17.4
Visibility: 2m
Sharks sighted: 7
Conditions: Calm, becoming choppy by the end of the day

The seas were calm and there were barely any clouds over head as we set out to Joubertsdam this morning. Within 10 minutes or so we’d picked our spot and began waiting for the sharks to show up. It took a little while but the first shark to visit was Poseidon; a 2.8-3m male tagged with the Ocearch in Mossel Bay earlier this year, and before long we had 3 or 4 sharks circling. A total of 7 sharks visited Slashfin ranging in size from 2.5-4m in length, we were also lucky enough to site several Southern Right Whales as well.

If you are looking to get up close and personal with the great white shark then Cage Diving South in Africa, and more specifically with Marine Dynamics, is a once-in-a-lifetime experience you won’t want to miss. Book online with us and get a free video of your encounter with the world’s apex predator.
