  • In Gansbaai, the largest white shark ever caught was at Danger Point and measured up to 5.9m. The exact world record white shark is a contested issue, but chances are it is between 6-7m.

  • 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.

Daily trip 20 September 2012

My initial love for the environment occurred at a young age when my father and I use to watch animal documentaries on Sunday evenings. I was hooked on anything ocean related when I saw these amazing submersibles going to such extreme depth in the ocean and discovering previously unseen things. To be the first to go somewhere where no one has been before was the first thing that attracted me to the field of natural sciences.

Guest comment: “Well worth the price! The most amazing experience ever! Crew is amazing, as well as overall service. Thank you for a great day!” Lizette, Jacqueline en Sjaan.

“Thank you! A very well organised trip. Extremely impressed by the experience and helpfulness of all staff!” Hinna.

“Who’d have thought a hagfish would be the scariest part of Shark Cage Diving. Awesome! Thanks.” Matthew.

Depth: 8.9m
Visibility: 4m
Number of Sharks: 5
Conditions: sunny and calm initially.

It was an extremely diverse day, with heaps of different wildlife to be seen! The start to our day was early in order to avoid the afternoon’s weather that was scheduled to come in and the wind definitely started to howl later on in the trip. The sharks were a bit stubborn today and kept us waiting for quite some time; this was however not a problem. We had an amazing bunch of people on board and the weather was great, it seemed to be a social gathering of a bunch of mates. The sharks did arrive eventually and everyone had their turn in the cage. Even our volunteers braved the cold waters as a final good bye just before they embarked on their future endeavours. The hagfish today certainly scared people more than the sharks did, that was hilarious, thanks for the great laughs guys! Finally to end things off, we stumbled upon a ‘bait ball’ of fish which were being harassed by gulls from above- and snoek from below water. An amazing spectacle...
