• 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 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.

The Bronze Whaler shark is a species of shark that is not historically associated with shark cage diving, however, since 2017 we have frequently encountered these sharks during our tours to the point that they can affectionately be heard referred to as the golden sharks of Gansbaai. The Bronze Whaler shark is not as well known as other species such as the Great White shark, just the mention of the name can draw blank looks and requests for more information. It is for this reason that it only seems right to delve into the Bronze Whaler shark and give this species a little of the spotlight.

The Bronze Whaler shark is a species of requiem shark (Requiem sharks - a migratory, livebearing shark of warm seas, sometimes also found in brackish or fresh water) and is known as Carcharhinus brachyurus in the scientific community, the genus name Carcharhinus is Greek for sharp nose whilst the specific epithet brachyurus is derived from the Greek word brachy (short) and oura (tail). This species is also commonly known as the Bronze Whaler, Copper shark or Narrowtooth shark, with the common names having much to do with the bronze or copper colour seen on the sharks dorsal surface and the shape of its teeth. Interestly, the name whaler comes from the association of this species, and a few others, with whaling activity in the 19th century as large groups would gather around harpooned carcasses.

This species is found in warm temperate to subtropical waters of the Atlantic, Indo-Pacific and Mediterranean. This shark is the only member of its genus largely found in temperate rather than tropical waters (12°C and above). Bronze Whalers can be found from the surf zone to slightly beyond the continental shelf in the open ocean, diving to depths of 100m or more. This species commonly enters very shallow habitats, including bays, shoals, and harbours, and also inhabits rocky areas and offshore islands. Populations of Bronze Whaler sharks in both hemispheres perform seasonal migrations, in response to temperature changes, reproductive events, and/or prey availability; the movement patterns differ with sex and age.
