  • 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.

Loction: Dyer Island
Sea Surface Temp: 14.8C
U/W Visibility: 5m

Another remarkable winter trip! On arrival at Dyer Island, we got our first shark sighting immiediately and the action just continued. It seems many of the sharks were re sighted from the day before,  on the West side of the island. We saw 14 sharks in total, ranging in size from 3 to 4.5 meters, predominently males. It was really lovely to see 'Flap' who is a 3 meter male shark we first identified on the 21st of April 2010 due to the fact he had a section sliced out of his snout area. We re sighted this shark in August 2011 and October 2011 and I have not seen him since. His injury seems to have healed nicely now, however it took longer than usual, possibly due to the extent of drag exhibited at the front of the the sharks nose, and parasites possibly keeping the wound open longer. Another reminder of how important it is to be out photogrpahing these animals on a daily basis! Well done to all who double dived!
