  • 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: 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.

Location: Geldsteen

Temperature: 16.4C

No sharks: 20

Visibility: >10m

Today was the best visibility I have encountered whilst in Gansbaai! The warm crystal clear water made for the most spectacular dive. Shark action was impeccable and non stop from arrival to departure, with over twenty sharks ranging in size from 2.8m to 4.8m. One of these was 'Andre' a 3m male shark tagged by us on the 8th of May.  We know Andre has spent time offshore and in Struisbaai to the east of Gansbaai recently, but has not strayed too far from the Dyer Island vicinity. I got in to the cage myself and couldn't believe how stunning it was! We were watching a large skate (similar to a sting ray) on the sea bed, seemingly unphased by its larger cousins circling above! Tami Kascke one of our dearest research assistants had her last day on Slashfin with amazing memories of a remarkable dive.
