  • 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.

Author: Alison Towner (Marine Biologist)
Alison has always been fascinated by the Great White Shark - to such an extent that it is believed that she might have been one in a previous life! This qualified PADI instructor and SAMSA skipper who also boasts a BSc(hons) degree in Marine Biology, and an MSc in Zoology. She is happiest at sea where she can study and observe these apex predators in their natural environment and help find solutions to protect them through education and international policies.

Location: Channel Mouth
SST: 14.6 Celcius

Today we had predominently male sharks - perhaps they knew it was fathers day! Due to a North westerly wind picking up we were limited as to where we could dive , so we setlled on anchor in lthe lee of Dyer island just outside the mouth of Shark Alley. It seems that some of the sharks we have been working with on the adjacent side of the island days before, made the same decision.. much to our delight! We saw a nice range of sizes with smaller sub adult sharks beginning the trip and larger sharks up to 4 meters long ending the trip for us. Everyone had plenty of dive time, most people dived twice! Our very own ecologist Nicola Stellueto was joined by his father on board who thoroughly enjoyed the view from the spacious top deck of our vessel Slashfin (see pics below). Another special Dyer Island winters trip!
