  • 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.

Daily trip 18 September 2012

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.

Guest comment: “Thanks a lot! It was a great experience. We were happy to see sharks, seals and whales!” Anne and Flo.

“Such a great day! Wonderful memories made today. Keep up the good work!” Julie.

“Amazing volunteers-definitely go above and beyond! Great trip- highly recommend!” Lauren and Ben.

Location: Dam
Water Temperature: 15.7 'C
Depth: 7.6m
Visibility: 3m
Number of Sharks: 10
Conditions: Swelly and windy.

We had quite an early start to our trip today, with all our clients needing to get up very early in order to meet us for our trip. It was well worth it, because the sharks put on a very nice show for all on board. Even though the wind was prevalent today it was still enjoyable out at sea, even for those who felt a bit green. We ended our dive with a visit to Dyer Island and on route we spotted a Southern Right Whale just cruising around the Island, quite spectacular! We had another sighting of our prop scar shark today; I hope to still see it every day. Get well soon my friend...
