  • 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.

Location: Joubertsdam
Water Temperature: 14.9°C + 15.1°C
Depth: 9.8m + 10.2m
Visibility: 1.5m + 1.5m
Number of Sharks: 0 + 0
Conditions: Little to no swell and wind, consistent rain throughout day.

Like we have no control over the wildlife we have no control over the weather, an unfortunate but true statement, one that was seen in full force today with a constant stream of rain ranging for light drizzle to the heavier stuff, our guests were prepared to get wet today either way! Apart from the rain the conditions were otherwise fantastic with little to no swell or wind and relatively warm and clear waters for this area.

The first trip launched at the early hour of 7am, amongst many of the other shark cage diving vessels in the area. Once on anchor we had a brief sighting of a Copper shark however it disappeared and did not surface for some time. It was then that we decided to make the move to another anchor and saw a few more Coppers, unfortunately a little on the shy side today and a very persistent and active Cape Fur seal, one that we have seen over the last two days.

Slashfin headed back to sea with our second group of guests and had its’ first Copper sighting soon after re-anchoring. The Copper sharks were a little bolder this trip with a few of the animals approaching the cage and appearing close to the surface rather than deeper down.
