• 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.

2021 Amendments to Line Fishing Permits to Protect Shark Stocks

Monday, February 08, 2021 |  0 Comment

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.

A major win for South African shark species is the newly implemented slot size limits for all species of sharks targeted by line fishermen.

Issued on 14 January 2021 these updated regulations to the Traditional Linefish (Zone A) permit conditions by the Department of Environment, Forestry and Fisheries, will help further reduce pressure on declining shark species along the South African coastline. Under the new regulation it is completely illegal to catch and retain any shark species measuring more than 130cm total in length. This is the measured length (straight line) from the tip of the shark’s snout to the tip of its tail. The amendments allow for permitted line fish anglers to catch the more commercially valuable sizes and spare the larger potential breeders, which will ultimately ensure a more sustainable fishery. The penalty for catching oversized sharks will be a large fine, confiscation of the catch and confiscation of the angler’s line fishing permit.

These regulations will go a long way in preventing resource conflict such as the catching of bronze whaler sharks (which are all usually above 200cm TL) in areas designated for cage diving. Marine Dynamics, together with other operators, has been at the forefront of this discussion. “These regulations can be considered a big step forward for shark conservation and the ecological health of South Africa’s marine environment,” said Wilfred Chivell, owner of Marine Dynamics and founder of the Dyer Island Conservation Trust.
