  • 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.

It has been two days since we were last on sea due to some not so nice weather conditions so we were not sure what we would experience today however our first trip had our first White shark sighting within 15 minutes with a juvenile female we first encountered with year only a few days ago, with easily distinguishable marks including a scar on the right trunk and stunning behaviour around the boat she turned out to yet again be one of the most active of the trip. Soon after her arrival more sharks appeared including some of our favourites, “Mini Nemo” the juvenile male with a shortened right pectoral fin and “Sarko” a juvenile female we were able to get to know very well last year. Towards the end of this trip our smallest and largest sharks of the morning showed up with a small, pale shark estimated at only 2.0m in length and a large female approximately 4.5m in length rounding out the trip. This trip also had he Short-tailed stingrays coming and going from the surface. We made our way back to land around Danger point due to low tide conditions in Kleinbaai harbour.

The second trip of the day picked up where our first ended with a trip back around the point and into the Shallows with sharks re-appearing 15 minutes after arrival as an estimated 3.5m and 3.0m female were spotted. “Mini Nemo” and the female with the scar on the right side returned for this trip as did the Short-tailed stingray. The smallest of this trip was a 2.5m juvenile and the largest a coming in at an estimated 4.2m in length.

After launching for our third trip we were heading straight to our dive site in the shallows. As we got to our cage we already spotted a shark circling it. We quickly go dressed into the wetsuits and were ready to have a close up experience with these mystic creatures. Our first shark was a 3.5m female, which we had around the boat the last few days already. She was with us during the whole trip and was showing up nicely. In total we spotted six different individuals and the biggest one was estimated to be around four meter. On this trip we also had a Giant Petrel coming closer to the boat nibbling on the bait line, as a shark tried to take a test bite of this large pelagic bird. Luckly the bird got away this time! After great shark activity we packed up and were slowly heading back home towards Kleinbaai.
