  • 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.

It has been a while since I’ve seen the number of sharks jumping, as seen on the trip today! We were pleasantly surprised firstly by the prompt arrival of all the sharks and secondly by the display of aerial acrobatics! The sharks were all in the range of between 3.5- and 4 meters. You could clearly see that they were still full of youthful energy! Conditions on the water held up quite well considering that they predicted rough weather. We did find some swell, however our anker spot behind the Island was perfect. We had some big screams and amazing sightings, all and all we had an amazing day! See you tomorrow...

Even though we had some chilly and wet conditions on the boat we had an amazing time! The sharks arrived very promptly and our clients were able to take shelter from the weather on the lower deck behind our protective tarps! The rain was on and off for the most part of the trip. It helps however to be one of the biggest boats in the business, especially on a day like today! Unfortunately, one of our seal decoys fell victim to the open ocean and drifted away towards greener pastures, we will miss him dearly :)! Our biggest shark was about 3.9 meters in length, just shy of the 4 meter mark! A truly phenomenal day with amazing activity! Great stuff...

Another sunny, clear, winter trip at Dyer Island. The first sharks to arrive were juvenilles within the 2.5-2.9m size range, one with a badly damaged dorsal fin which we think may have been caused by fishing line. We really enjoy seeing smaller sharks, as they often have such a bold and inquisitive nature.

The action still continues with Marine Dynamics shark cage diving! We had an awesome spot to ourselves in Shark Alley with no distractions from other vessels! The activity was stupendous with no waiting time, when we were putting the cage in the water our first shark arrived at the boat! The Australians on board gave credit to the South African Great whites and mentioned that our sharks are really impressive! This is how we do it here in SA...

We had an American invasion on the boat today! Normally we have quite a diverse range of nationalities on board, but not today! It made for very interesting conversation, but no politics were discussed :)! Our sharks gave everyone a fantastic time in the cage with amazing passes. We were also very lucky to have spotted two separate groups of penguins making their way away from Dyer Island; these guys are always a welcome sight amongst guests! Our subantarctic skuas came dangerously close to leaving a couple of presents on people’s heads today; luckily no one got hit by poo! What a great day...
