• 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.

This morning’s trip was the second of four, research based trip for the study group joining us from Italy under the guidance of Dr Primo Micarelli. Unfortunately, like yesterday morning, this trip also did not see any White sharks but had the Copper sharks present as has been so for the last few weeks.

The second trip of the day headed out and was met with a slight increase in the wind causing some choppier conditions than earlier, the Southern Right whales and African penguins in the bay appeared to enjoy said conditions and we had a nice view as we made our way back onto anchor. The Copper sharks arrived relatively quickly and the group was eager to get straight into the water with them. Whilst no White sharks showed up for this trip nearly all the guests on board did take a dip into the water with the Copper sharks.

Our third and final trip of the day launched and much like the previous two had the Copper sharks appear very quickly. Whilst not exactly the species that guests are looking for these sharks are beautiful creatures and have some very interesting behaviour, especially as they are usually in pairs or schools, something we do not see with our White sharks.

A big thank you to all our guests for joining us on board Slashfin today, you all showed great patience and understanding, something that we highly appreciate at such uncertain times as these. We simply cannot say when we will see White sharks again, it tomorrow it could be the next day, we’re all hoping it is very soon!
