  • 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.

An interesting start to our trip was the sighting of a dog swimming randomly in the sea; it must have been a dolphin in its previous life :)! Very odd indeed. We then carried on with our voyage and were greeted by the sharks in very timely manner! The guests were caught a bit off guard when we started to ask who our first seven divers were going to be. “Big Nemo” made her infamous appearance and was off again. Taking up her limelight was a shark riddled with parasites. This shark stayed with us for the entire duration of the trip and put on a great spectacle! There were many box jellies in the water as well as blue bottles which were quite interesting to see. It was fantastic to see all the diversity in the water today! Great stuff...
