  • 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.

The first trip of the day enjoyed the beautiful sunrise as we made our way around Danger Point from Gansbaai harbour, not our usual, Kleinbaai harbour due to low tide. Once on anchor we had a little wait for a shark sighting with a Short-tailed stingray beating our White sharks to the first wildlife sighting of the day. The shark however appeared soon after, a juvenile White that made a few passes by the decoy and bait line before disappearing, never to return, well for this trip anyway. Unfortunately we did not see a shark again, however we were lucky as things seem to have taken a turn for the quiet in regards to sightings through the bay for the last two days for all operating this activity in the area. The rest of the trip saw the Short-tailed stingray and two very friendly Cape Fur seals engaging with the boat and cage. A big thank you to our guests from this morning for their patience and enthusiasm from the launch to our return to the close by Kleinbaai harbour. Back on sea for our next group of eager shark viewers, the team moved anchor quickly after arriving and no sooner had this happened a shark appeared, a different individual than the one seen on first trip, larger, measuring in at approximately 3.0m this male White shark made some passes before disappearing only to re-appear at the end of the trip and wow all those onboard. Not to be left out the Cape Fur seal put in an appearance during this trip as well. The final trip for the day launched and in the first hour was only greeted by that seal yet again. The group put in a tremendous effort staying on the water most of the afternoon with one very brief sighting of a White shark experienced, along with some whales too. We thank all our guests today for their patience and understanding!
