• 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.

Today was one of those special Dyer island days, the type of day we wish for all year round. As we anchored, I looked down into the water and every rock on the sea bed was visible, this meant  one thing, if we got sharks, our group were in for a stunning dive! After only a ten minute wait, we were blessed with the presence of Slashfin, one of our all time favourite male sharks, who is now looking incredible at 4.5m in length. I've been watching this shark return to Dyer island for five years and he has grown substantially the past two years- both in lenght and width. In all, 14 sharks paid us a visit raning in size from 2.9-4.5m TL both males and females. Other familar fins included Zane (a 4.0m male whom which we actively tracked last year- see,  and Dorien a 2.9m satellite tagged  female from the recent Ocearch expedition). One shark  was accompanied by a small remora fish on the right side fthe dorsal fin (see picture).Incrdieble dives were had by all, and to top it all off ,a pod of  approx 50 bottlenose dolphin fled past the boat in the distance. The speed at which they swam and tight nitted nature of their pod indiated that they were fully aware of white shark abundance around the island!

If you are looking to get up close and personal with the great white shark then Great White Shark Cage Diving in Gansbaai, and more specifically with Marine Dynamics, is a once-in-a-lifetime experience you won’t want to miss.
