  • 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.

Even though it was Valentine's Day the sharks showed us no love and we experienced our 6th day of no shark sightings. Great patience was shown by our group today with a 3 hour anchor in the Shallows before we headed to the Islands for a look at the Cape Fur seal colony on Geyser Rock.

We would like to extend a big thank you to all those that joined us today for their patience and understanding, we truly appreciate it.

We hope to have some good news soon, news which can be followed here on our daily blog page or Marine Dynamics Facebook page here.
