  • 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.

My initial love for the environment occurred at a young age when my father and I use to watch animal documentaries on Sunday evenings. I was hooked on anything ocean related when I saw these amazing submersibles going to such extreme depth in the ocean and discovering previously unseen things. To be the first to go somewhere where no one has been before was the first thing that attracted me to the field of natural sciences.

It is amazing how the visibility has remained so good for the last few days; it is really an added bonus to the entire experience. We were celebrating a couple of newlyweds on board today who decided that shark cage diving would be the ideal thing to do to strengthen their relationship. I think after today they will remain together for a very long time to come! We had lots of large sharks today with our regular smaller 2 meter individual making his appearance! We had a real treat today when we sighted a large 3.8 meter shark in shark alley, the waters were crystal clear. The seals were less than 2 meters away from it at times, however no predation took place to the great disappointment of all the guests :)! A tremendous day...
