• 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.

A beautiful sunrise start as we set sail for the anchor site. We saw two Brydes whales blowing in the distance. A red tide and lots of seabird activity suggests high productivity in the area and we believe there may have been a few baitballs subsurface, possibly anchovy. First to show up at our boat were the bronzies - five of them - then appeared Mini-nemo to rule the roost! It is always amazing to see a large white shark right after the bronzies, the hierarchial procesws of know your place and size matters applies and you really see the behavioural differences between both species with bronzies making frequent slow passes for the divers and a large white shark bursts through the water at the bait and decoy. Two huge shorttailed stingrays also appeared and to round the trip off, an endless entourage of Cape cormorants flocked alongside our vessel for what felt like the entire journey back to the harbour. 

For the second trip we headed back straight back to our dive site, and barely had we arrived and we saw our first white shark. Our divers quickly climbed into their wetsuits and were soon in the cage. We had a total of five great whites come up to our bait, including old favorites like Mini-Nemo and Clubtail. The white sharks were amazingly active, coming up out of the deep to put our baithandlers to the test. Every now and again a bronze whaler got the guts to visit the cage, and even the two short-tailed stingrays came up to visit our guests. With the amazing activity around the boat, our guests had a fantastic time seeing the sharks from our vessel.
