  • 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.

Daily trip 28 May 2012 | Great White Shark Diving South Africa

Author: Alison Towner (Marine Biologist)
Alison has always been fascinated by the Great White Shark - to such an extent that it is believed that she might have been one in a previous life! This qualified PADI instructor and SAMSA skipper who also boasts a BSc(hons) degree in Marine Biology, and an MSc in Zoology. She is happiest at sea where she can study and observe these apex predators in their natural environment and help find solutions to protect them through education and international policies.

Another sunny, clear, winter trip at Dyer Island. The first sharks to arrive were juvenilles within the 2.5-2.9m size range, one with a badly damaged dorsal fin which we think may have been caused by fishing line. We really enjoy seeing smaller sharks, as they often have such a bold and inquisitive nature. Then arrived the larger sharks, measuring between 4-4.5m. One really impressive female shark made the most amazing passes by the cage, completely ignoring the bait line, she eyeballed the divers time and time again! In all, stunning top to bottom visibility (approx 10m) and water temperature of 16 degrees celcius, made for the perfect dive. We saw 14 sharks in total.

If you are looking to get up close and personal with the great white shark then Great White Shark Diving in South Africa, and more specifically with Marine Dynamics, is a once-in-a-lifetime experience you won’t want to miss.
