  • 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.

Marine Dynamics welcomes Mike Horn and his Young Explorers!

Author: Michelle Wcisel (Marine Biologist)
To Michelle, a born and bred American from Michigan, the sea resembles another planet within Earth where intelligent "extraterrestrial" beings and thriving systems flourish in the depths where there is neither oxygen nor sunlight. "So many of us gaze at the stars in wonder when we should be looking into our oceans!"

We at Marine Dynamics shark tours were stoked to have Mike Horn and his group of Young Explorers on Slashfin yesterday! Mike is without a doubt one of the most world-renowned explorers who has famously accomplished a solo journey around the equator without motor transport as well as a two-year 3 month solo circumnavigation of the Arctic Circle in 2004 - and that's only to name a few. With this knowledge and experience, he created the Mike Horn Young Explorers program which takes young driven individuals across the world aboard their unique sailing vessel Pangaea (pictured below). They participate in educational programs and activities around the globe, and we were excited for the chance to show these future world changers the magnificent white shark.

As if this wasn't awesome enough, we were also able to catch up with their Young Explorers program coordinator, none other than former Marine Dynamics shark biologist, Michael Scholl! Our boat has definitely improved since the early 2000s, but the sharks were hopefully the same.

Pangaea!
