  • 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 14 September 2012 | Shark Diving South Africa

Author: Oliver Jewell (Marine Biologist)
Born in London, England, Oliver has been in South Africa for the past 4 years after earning a BSc (hons) in Oceanography from the University of Southampton. His first experience with Great White Sharks was similar to many people's only experience - watching the film Jaws. Since that day, he has been dedicated to learning everything he could about sharks and ways of protecting them.

Location: Joubertsdam
SST: 16.1’C
Depth: 12m
Visibility: 3m
Sharks Sighted: 10 & 10
Conditions: Strong winds from the east

Today was one of the busiest in Marine Dynamics history! We hosted over 200 guests from across the globe and all attendees of the International Aquarium Congress (IAC) in Cape Town. 3 whale watching and 5 cage diving trips were launched and events ran through the day. Aboard Slashfin we had two of the trips and we were blessed with some amazing shark sightings. One of the first sharks we saw was a large female nicknamed ‘Evil Fin’ by our volunteer Ben on account of a nasty gash in her fin which has made her extremely distinctive the last few years. This massive animal is clearly over 4.5m in length and possibly as big as 5! She stayed with us the entire day and was a prominent visitor for both our trips. We sighted plenty of her friends too with 10 sharks on each trip. The wind was definitely up which made for a chilly and choppy day on the water but Aquarium folk are tough and barely anyone was seasick, the sharks were the stars of the show however and I’m sure this will be a day remembered by all lucky enough to spend it with us!



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