  • Shark cage diving in Gansbaai, South Africa with Marine Dynamics. Experience the exceptional and come face to face with a great white shark! 

  • The exact world record white shark is a contested issue, but chances are it is between 6-7m. In Gansbaai, the largest white shark ever caught was at Danger Point and measured up to 5.9m.

  • 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.

06/04/13 Trip 2
Location: Dyer Island
Visibility: 5m
Water Temp: 14.5'C
Sharks Sighted: 5 + 1 predations
Conditions: Slight swell

My first trip of the year back at Dyer Island and I have definitely missed the winter sharks! We anchored East of Dyer Island in the Rocky Bay/Doldrums area and picked up our first few sharks in quick succession. The first had a damaged pectoral fin, perhaps caused by fishing gear, however was undeterred by this injury and was probably the quickest shark of the trip! We’ve seen sharks recover from much more serious injuries than this and even when entire fins are missing, so we hope this shark will be able to survive this disability. The other sharks sighted were fairly large; we had a 4.5m male with copepods around its face and another larger shark which kept its distance. Finally on our way to see the seals we saw a predation in Shark Alley; a seal had been swimming carelessly in the middle of the Alley and nature took its course. We could not make out any sign of the upper caudal so there’s a good chance this was one of our Dyer Island regulars, the legendary ‘Zane’. It was also a pleasure to have my good friend Ryan Reisinger and his girlfriend Carin aboard, Ryan has been collaborating with our research team on a publication and joined us to see the sharks himself this afternoon.
