  • 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 lower tide called for a Gansbaai launch again this morning and we enjoyed a pleasent cruise around Danger Point with a Southern Right whale spotted as we made our way into anchor in the Shallows. The cage had already been placed out earlier in the morning before we collected our first trip guests and once on anchor we spotted a White shark quickly, gliding just under the waters' surface in the distance yet this little shark had no interest in approaching us and after waiting it out for the next hour an anchor change was on the cards. We moved a little further out into the bay and as some of our guests took to the water even with sharks around the first shark appeared! A large individual that kept deep and did not want to come to the surface however shortly after seeing this one another appeared, Scarletjie, a 4.0m female, frequent visitor to the boat over the last week with easily identifiable scars all over her head and trunk and with her tail tip missing, she made some great passes and in turn saved our morning out on the sea.

The second trip of the day also encountered a White shark quickly after arriving back on site. This was a juvenile White shark, estimated at 2.0m in length and very pale in its' dorsal surface colour. It kept deep, the increased visibility allowing the crew to see these passes however he did come to the surface once giving the guests on board a nice view. Things did go quite after this and soon the boat made its' way back to the harbour.
