• 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.

Sunshine and sharks?? Yes please!! We’ve been very fortunate to have some stunning weather conditions the past few days and today was no exception. As Slashfin anchored at our dive locations and our wait began, the jackets began to come off. The sun was heating up the bay and our divers were grateful for it after experiencing the fairly chilly water. We had to wait about an hour for our first shark to arrive, a 3-meter white shark with curiosity like a cat. It was fascinated by our seal decoy and was soon joined by a 2.6-meter white shark who was fascinated not by the seal decoy but the bait line. The first shark disappeared as another 3-meter white shark cruised up to the cage. These two sharks spent quite a while with us, venturing off while our last group was in the cage. Some of these divers were also lucky to see a short-tailed stingray up close as it surfaced near one side of the cage! 

Our second trip headed out into some glorious sunshine this afternoon, and within minutes upon anchoring up we had ourselves a white shark! This 3m male is an individual that we have been seeing over the course of the last few days, with some fairly unique markings on the right side of his dorsal fin he is nice and easy to identify. We had a few nice passes from him for our first cage divers, but he came back with some more energy for our second group! One of our younger divers was absolutely thrilled to get so close to this magnificent animal in the water. We were then joined by our second shark of the trip, another male slightly bigger at 3.3m and a little paler in colour. He was also full of energy in this marvellous afternoon sun, we managed to get our first group of cage divers through the cage again the activity was that good! This afternoon demonstrated that numbers don’t necessarily mean anything, and it is always awesome to see white sharks around Slashfin!
