  • 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 2nd June 2012 | 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.

Winter at Dyer Island just keeps getting better! We had yet another spectacular trip today, with 15 individual sharks some measuring between 4.5 and 5m! On arriving at a reef to the west of the island, we were busy watching a shy albatross saw gracefully through the sky, then all of a sudden a huge splash occured and the seagulls flocked to it- it was a natural shark predation on a cape fur seal! Our luck continued with very active sharks and stunningly clear water visibility. One shark with a distinctive tumour like growth on its right flank I recognised from the same time last year and have not seen him since. The growth seems to be from some sort of injury, possibly a bite from another shark. Regardless, this male sharks health must be fine as he has grown substantially since last year.  The day was topped off by two full breaches one just off the stern within ten meters of the boat.. Incredible!
