  • 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.

A beautiful Sunday morning greeted us today with great conditions both above water and also underwater, with calm seas, blue skies and clear water! We launched early and made our way into the Shallows with our first group. We anchored and waited patiently however it wasn't a long wait as our first shark appeared, a Copper shark or Bronze Whaler. Copper and bronze seemed to be the theme of the day as the morning progressed with this species of shark coming and going from the boat, we could also track their movements when they went deep due to the great visibility! Slashfin made a slow return to harbour at the end of the trip, with such phenominal conditions out on the water we wanted to enjoy what the day had on offer and went for a cruise through along the coast. Here we spotted three Humpback dolphins frollicking in the surf and multiple cow calf pairs of Southern Right whales appearing to be doing exactly what we were, making the most of a stunning day on the water.

The second trip launched and enjoyed views of the Southern Right whales that were spotted as we made our way back onto anchor. Once on anchor we waited some time before a that sharky silhouette was seen cruising deep down along the bays seabed. These sharks yet again kept up with some nice sightings throughout the trip coming and going from view as did a juvenile Cape Fur seal that looked content on practicing its hunting skills on the mullet schooling around the boat. To finish of the day we headed deeper instead of shallow like the first trip and made a side trip to the island system to have a closer look at those Cape Fur seal inhabitants of Geyser Rock.

A wild day out on the water with wildly perfect conditions and a big variety of wildlife encountered.
