Great White Shark legend returns

Marine Dynamics and the Dyer Island Conservation Trust are excited to announce that legendary shark “Slashfin” has been spotted again, and better yet, tagged. 


 
“I couldn’t believe it when I saw such a massive shark swimming past Lwazi, and that it was Slashfin was a huge bonus,” said Marine Dynamics marine biologist and resident DICT scientist Oliver Jewell. “I have always wanted to tag Slashfin and this was my big chance!”

Slashfin is what we consider a “regular shark” that returns year after year and utilizes the same hunting areas.  However, Slashfin had not been spotted since 2010 World Cup and we began to fear the worst.  “It’s depressing when a shark that you know comes every year doesn’t turn up,” Oliver explains. “The reality is, these sharks are fished and can be caught in shark nets, so you never know when will be the last time you see them.”
 
Luckily this was not the case.  Not only is Slashfin back, but he’s massive and hungry, topping out anywhere from 4.0-4.5m in length and with more predations being recorded in Shark Alley than in previous months.  “This is supposed to be the ‘low risk’ part of the year for the seals when they can get away with being more relaxed,” explains Michelle Wcisel, DICT animal behaviour researcher. “Already you can see the seals are definitely changing their behaviour.  I would too if I saw Slashfin in the water!”
 
It’s this dominance that inspired Marine Dynamics owner, Wilfred Chivell, to name the company’s new purpose-built cage diving vessel after Slashfin.  Slashfin the shark met Slashfin the vessel this past week, with one slow pass – enough to make everyone excited on board!

So far, Slashfin is teaching us more about how “experienced” sharks hunt in the area.  Since he’s a regular, he knows the areas that work best for catching seals under the best conditions.  Compare it to moving into a new neighbourhood and trying to find the best restaurant.  The first few months, you try everywhere, but the more time you stay the more you become selective and only go back to your favourite places.
