• 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.

All Rounder

You might have seen him on Shark Week doing crazy stunts with Great White Sharks, now learn more about Dickie Chivell behind the scenes. 

Dickie Chivell is the son of our CEO, Wilfred Chivell. Passion for marine wildlife has been passed on from father to son.
Dickie is an accomplished skipper, a qualified commercial diver as well as a scuba diving instructor and has completed his tour guiding course. He is a passionate conservationist and highly knowledgeable about the Marine Big Five of the Dyer island Nature Reserve in Gansbaai, South Africa. Dickie is a skilled marine life photographer and has completed a short course in video journalism.

Dickie has spent some time working in Baja with the Grey Whales, filmed with Discovery in New Zealand and travelled to various other shark hotspots such as California and Guadalupe. His appearance on Shark Week from 2014-2016 has been a life-changing experience and especially working with the likes of Chris Fallows, Jeff Kurr and Andy Brandy Casagrande. He is a true ambassador of marine conservation and has supported The Dyer Island Conservation Trust with white shark tagging and tracking with Marine Biologist Alison Towner. When he is not skipping a boat or working toward conservation, you will find him on his surfboard catching sick barrels.

“I am extremely grateful for the travel adventures, meeting inspirational people from around the world and learning new things through working with Marine Dynamics Shark Tours and Dyer Island Cruises”.

His hero in the wildlife filming world is David Attenborough.
“An understanding of the natural world and what's in it is a source of not only a great curiosity but great fulfilment,” D. Attenborough.
