  • 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.

Marine Dynamics owner awarded life membership to the Shark Conservation Society!

Author: Marine Dynamics (Shark Cage Diving Company)
Marine Dynamics is a Shark Cage Diving company based in Kleinbaai, a small harbour town, part of Gansbaai in the Western Cape of South Africa. This area is known as a hotspot for the Great White Shark and the best place in the world to see and dive with these iconic creatures in their natural environment.

From the SCS page: “The board of the Society is delighted to announce that Wilfred Chivell has accepted Honorary Life Membership (HLM) of SCS. Wilfred is a committed "action type" conservationist who founded the Dyer Island Conservation Trust. He is also the owner of Marine Dynamics (a Gansbaai shark ecotourism operator) and a well known figure in marine wildlife circles in South Africa's Western Cape. Within SCS there has always been the belief that in general life, and in conservation, there are the 'doers' and the 'talkers' - Wilfred is very much a doer!

Wilfred founded the Dyer Island Conservation Trust (DICT) in 2006 to focus on the conservation and protection of the greater Dyer Island region.  This includes one of the largest aggregations of white sharks in the world, one of the last African penguin breeding colonies, as well as the various whales/dolphins in the area.  Through Wilfred’s vision, the DICT has contributed only to research programs that directly benefit the conservation and understanding of the animals they concern.  This philosophy is mirrored in the two eco-tourism companies Wilfred operates, Dyer Island Cruises whale tours and Marine Dynamics shark tours, as each company continually improves upon the ethical standards of both whale watching and shark cage diving.  

Congratulations Wilfred!
