  • 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.

Sightings:  Great White sharks, Bronze whaler, Short-tail stingray and Cape Fur seals

Location: Joubertsdam

Water Temperature: Moderate

Visibility: Moderate

It was an early start for Slashfin's first groups of guests this morning as we tried to make the best of the nice weather gap with a launch onto a calm bay as the swell, wind and rain stayed away for the morning before coming through later in the day. The first boat into the Shallows we were on anchor for only moments when a Bronze whaler was spotted before another individual also joined us, however it wasn't long before they disappeared and whilst we wondered briefly why they had left so quickly it was soon clear as the outline of a larger, broader shark came gliding into view. This was Shaun the shark, a male Great White approximately 3.3m in length and one that has been treating us to his presence on and off for the last month. He made some beautifully close and slow passes by the cage allowing our guests to enjoy views of this stunning animal. Before our last cage entered the water we unfortunately lost Shaun the shark but with a quick anchor change the rest of the divers were able to experience the awe-inspiring moment that is coming eye to eye with a Great White shark. With time to spare and conditions still nice out on the bay we used the rest of the morning to head to the Islands and have a closer look at the Cape Fur seal colony of Geyser Rock.

The second trip of the day launched into the rain but this did nothing to dampen the shark activity as Shaun the shark reappeared quickly for this trip and thoughout the trip giving more great views for the day. The Bronze whalers were also present throughout the trip, taking advantage of some of the quiter times when the Great White shark had gone deep or into the distance for a while. The Short-tail stingray appeared again this afternoon, also taking the quite times from shark activity to glide from the depths before disappearing back to where it came from.
