  • 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 is amazing how the visibility has remained so good for the last few days; it is really an added bonus to the entire experience. We were celebrating a couple of newlyweds on board today who decided that shark cage diving would be the ideal thing to do to strengthen their relationship. I think after today they will remain together for a very long time to come! We had lots of large sharks today with our regular smaller 2 meter individual making his appearance! We had a real treat today when we sighted a large 3.8 meter shark in shark alley, the waters were crystal clear. The seals were less than 2 meters away from it at times, however no predation took place to the great disappointment of all the guests :)! A tremendous day...

Today was so much more than just a shark cage diving experience, we were so fortunate to have loads of shark activity as well as various other animals in the area! Our day started brilliantly with lots of active sharks and amazing visibility. “Big Nemo” paid us a visit and she was looking very ravishing!  After our amazing shark diving excursion, our guests were welcomed by at least 20 bottlenose dolphins off the bow of the boat. They were truly an awesome sight. After that we ventured past shark alley to visit our friends the seals who were lazing about on Geyser Rock. Finally making our way back into port we had some subantarctic skua trying to grab some fish from our crew. It is amazing how these birds literally eat out of your hands. Truly a great day...

We had a very early start in order to get enough action packed into our day! We completed two successful trips today with lots of happy clients! The visibility in the water remained very good throughout the day which made shark viewing even more amazing! We had 10 large sharks all above the 3.5 meter mark and only 1 small shark! We had a massive flock of Cape Cormorants all around the boat in very dramatic fashion as well as a few Gannets diving for fish! The sharks were giving us an amazing display with several sharks being in front of the cage at one time! A really fantastic day!

What a fantastic day! The visibility was the best that I have seen in ages, that in conjunction with amazing sharks is a winning combination. The sharks arrived very quickly today and we had the first clients in the water before you could say ‘shark’! We had eleven large sharks, with one shark in particular showing all his pearly whites all the time. It spent more time outside of the water than in it :)! The water temperature drop has not gone unnoticed by the guests, however after a couple of minutes one gets use to it! Beautiful sharks, great visibility and awesome people made today a great trip...

Wow! We had a truly amazing time at sea today. The day started off on a wet note with heaps of rain, fortunately for us we were on a well equipped vessel. We simply released the side tarps and that protected us from all the rain, being the largest shark diving boat in South Africa has its perks! The rainbow was a good sign for us; the shark activity was very high with very close passes by the cage! The visibility in the water was amazing for most of the trip allowing for marvellous viewing, the rain offers some advantages. The sharks were passing time and time again and were all in the size range of about 3.5 meters. After the rain had moved on we were greeted by beautiful flat seas! It was an adventure packed day...

It was an extremely eventful trip today with lots to see. We were being invaded by swarms of blue bottles (only 3) and they made an interesting conversation topic for quite some time! Our infamous “Big Nemo” made an appearance to the delight of the crew, she really isn’t the pretty’s girl in the water, but she’s still fantastic! All our sharks were more or less 3.5 meters in length today except for our final shark of the day who was 4 meters in length. The sharks were not us energetic and jumpy as usual, but they compensated by giving some REALLY close passes by the cage. On our way back to harbour we were treated with a bryde’s whale sighting, these ‘small’ whales frequent this area very often and it is always a treat to see them! A great day...
