  • 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
SST: 16.2 Celcius
Visibility: 5m
No sharks: 15

Today we had a remarkable trip. After anchoring on a Western Reef of Dyer Island we saw 15 individual sharks some measuring over 4 meters in length! Roughly 70% of our sightings were animals we have been seeing over the last few weeks. 'Trevor' named by one of of our interns from England Oliver, stole the show, and at almost 4 meters long this male new he was dominant and entitled to first investigation of the bait line! We also saw a female satellite tagged shark from the Ocearch expedition. We are still waiting to get confirmation from the DEA on her indentity but given the Argos system data we are pretty sure it may be 'Brenda' a female tagged in Mossel bay during March this year. Plenty of giant Petrlols cirled us whilst our divers had numerous dives in great visibility! A perfect day.
