• 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.

Author: Alison Towner (Marine Biologist)
Alison has always been fascinated by the Great White Shark - to such an extent that it is believed that she might have been one in a previous life! This qualified PADI instructor and SAMSA skipper who also boasts a BSc(hons) degree in Marine Biology, and an MSc in Zoology. She is happiest at sea where she can study and observe these apex predators in their natural environment and help find solutions to protect them through education and international policies.

Location: South east of Geyser Rock
Water Temperature: 16.1 Celcius
U/W visibility:4-5m

Today we had an amazing trip despite the howling cold North Westerly wind blowing. In total we observed 12 white sharks, including one satellite tagged male shark 'Andre'. One enormous female arrived towards the end of our dives, I estimated her length 4.8-5m,she made the cage look small, so we thought it appropriate to name her the 'Tank-ess'. This is not a shark I recognise, she is completely un marked and untagged, except a singular red scrape on her dorsal fin. To see a white shark of this proportion is awe inspiring, her relaxed dominant behaviour illustrated how aware of her own power she is, at this length, if she isn't sexually mature, she is almost certainly near, which raises the question as to why she was patrolling an area full of large mature male sharks?! (recent satellite tagging in California has shown female white sharks of this size preferentially segregate away from harassing male sharks for most of the year).There may be more than just seals on her agenda, although white shark mating is something still yet to be observed anywhere in the world, it could well occur during winter off SA's coastline. Fabulous bird species glided by whilst we were on anchor, including a Blackbrowed Albatross Thalassarche melanophris, a Pintado petrol Daption capense and an adult Southern giant petrol Macronectes giganteus. Another stunning winters trip and some great dives had by all who entered the cage!
