  • 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.

One shark, two sharks, three sharks, seal! White Shark, Copper Shark, another White Shark!! *squeal!!!*

After not being at sea yesterday, we were hopeful for what today would bring us. There was a bit of swell and once we anchored, our divers got suited up, and the wait began. After learning how to identify a male and female shark, and learning how long the white sharks and copper sharks can live, there was a splash at the bait line. We had our first shark, and it was a big white shark!! It was such an exciting moment as this beautiful 3.8-meter-long white shark graced us with its presence. It wasn’t a shark that we could recognize and it made a few attempts at the bait and decoy before disappearing. The wait began again, but it didn’t take long before we had a new visitor- a copper shark! It made an attempt at the bait line then quickly swam away. Often times when a small shark swims away quickly, it means that something larger is around, and this it time rang true. There was a sudden splashing ruckus and we knew that we had something big around. Was it the 3.8-meter white shark from earlier? Was it a large copper shark? Or perhaps, it was one of our local favorites... It was! Mini Nemo came flying out of the water, surprising everyone with his quick speed and amazing grace. This male white shark is estimated to be about 3.4 meters long and we last spotted him on 13 February as well as in January. He is one of our iconic sharks and has been part of several of the DICT studies. He cruised around the boat, staying just beneath the surface, occasionally showing off just how well evolved these majestic creatures truly are. He stayed with us through our final cage, only leaving once our last diver exited the cage. What an amazing adventure out at sea with two beautiful White Sharks, a Copper Shark, and a Cape Fur Seal!
