  • 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.

Guest comment: “Best day Amigos! From breakfast to the sharks to the soup on return! Totally professional!” Matt.

“Literally the coolest thing that I have ever done! Crew was awesome, thanks so much!” Jamie.

“Absolute magic! Wish I could live down there. Thanks for the experience.” Kristy and Matt.

Location: Dam
Water Temperature: 14.7 'C
Depth: 10.2m
Visibility: 3.5m
Number of Sharks: 8
Conditions: Awesome!

We had the best weather and sea conditions today; it was sunny with very little wind and no swell. The sharks did keep us waiting a bit today, but when they arrived they did not stop and gave us some awesome passes. We did have a massive female shark swim pass the cage with a large prop scar to the base of its dorsal fin, not as large as the scar seen on another shark earlier in the week though. Our research boats were out in fall force today and our team of biologist were able to tag a 3.5 meter male shark with an acoustic tag. They then proceeded to monitor the shark’s movements in the area, which then brought them to our shark diving vessel! This just showed everyone on board today how devoted Marine Dynamics remains in its conservation and research efforts. Well done team...
