• 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.

With a storm coming through tomorrow, we launched this morning with our hopes high that we would be able to see some sharks before we wouldn’t be able to go to sea for a couple of days. Luck was on our side! With a quick 10 minute wait before we had our first shark, we knew it was going to be a great day in the bay. Our first shark was a 2.6 meter male that we’ve been seeing frequently. His behaviour changes throughout each trip. Sometimes he likes to sneak up on the seal decoy and bait line; sometimes he likes to swim deep in front of the cage, down  near our divers feet, and sometimes he likes to sneak up from under the cage, investigate the decoy and bait, then dive back down under the cage disappearing beneath the boat. We had another shark around as well, about 3.3 meters long with some healing wounds along its side. This shark had a tendency to stay deep as well, moving quickly around the boat. Activity was good throughout the trip, with all of our divers getting a second chance to dive! Most of our divers also got to see 2 short-tailed stingrays swimming in front of the cage, and one cage got to witness a Cape cormorant hunting the mullet around the cage. What a treat!

As we boarded Slashfin for the second trip of the day, we were excited to get out to our dive site! With all of Slashfin’s power, we made it out there in just 15 minutes and got ourselves ready to go cage diving! With the cage secured to the side of the boat, we had a shark pretty quickly this afternoon. Our first shark was the 3m male that we’ve been seeing over the last few days. He cruised around Slashfin with some grace this afternoon, giving our divers some nice opportunities to grab some underwater footage of the mighty individual. Soon after this we had our second shark of the trip another 3m male with the bite mark just below the dorsal fin. While he was swimming a little deeper today the extra meter of visibility allowed us to track him through the water. After this guy moved on we had a little lull in shark activity, yet we had a very active cape cormorant around the cage. This energetic guy was schooling the mullet in an attempt to catch an unlucky fish. As our guests became transfixed on the swirling school of mullet the shark that came from the bow of the boat caught us all by surprise. The role of the cormorant almost went from predator to prey as the shark stalked the unsuspecting bird at the surface! This or 3rd shark of the day was the same larger 3.6m male from the 1st trip! He eventually left the bird alone and gave us some nice strikes on the decoy line!
