  • 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.

Conditions: Clear day with a very small swell and wind increasing.

Back onto the water after a day off, we could still feel the reminents winds that caused us to cancel yesterday however it was less than yesterday and decreasing as the day went on. Slashfin was the first boat on anchor this morning and as we were cruising onto our spot a White shark was seen moving slowly by just under the surface of the water in the distance. We were hopeful that this shark would approach and keep us company for the morning however this was the only glimpse of the animal that we had. The Copper sharks were seen today, with some nice sightings of this species throughout the trip, made all the better by the wonderful visibility that we experienced.

The second trip of the day launched just after 10am and we made our back onto anchor in the Shallows. The Copper sharks appeared quickly and were consistent sightings for the trip, like the first trip the visibility was fantastic making for some great viewing of the sharks. Unfortunately no White shark sightings for this trip.

To finish off the day Slashfin headed out one more time to try our luck. The wind had died down for the afternoon and the conditions were beautiful for a day out on the sea. The Copper sharks yet again visited us and were more than happy to spend the afternoon with us, coming and going making for a 'Bronzie' sort of afternoon. We moved anchor towards the end of the trip and were rewarded by mini-nemo who we were more than happy to see swimming around us!
