Hey everybody!
With all you guys discussing shark behaviour - and especially the Oceanic Whitetips in Egypt - I wanted to share some of my, well, let's say, inside perspective. I am working as a dive guide and biologist on Egyptian liveaboards for the last more than 5 years. Since October 2004 I am specifically looking for the Oceanics and initiated a research project... (see www.longimanus.info)... building an individual catalogue, that now contains more then 500 individuals...
Ever since meeting them underwater, there have been very close encounters with these sharks, not that different from this year...
What is different this year is their unusual numbers around reefs, where they normally show up only seasonally. St. Johns however is one of the areas, where they have always been more frequent in the early summer months... And also one of the sharks now allegedly involved in one of the attacks has been around these reefs at least since 2008. She was highly pregnant last summer, and showed up again this spring/summer. I have met her three times underwater and she has never been aggressive - inquisitive, yes, but never aggressive... so there is no reason to classify her (or any of her conspecifics) as dangerous maneaters!!!
One of the statements made above I can definitely confirm: with food present, these sharks do become more erratic, pushy and aggressive. Which is a particularly serious issue as a snorkeler, which has been proven by a variety of - until this June - fortunately mainly minor incidents.
A lot of factors are contributing to that behavioural change, hunger and the search for food, possible competitive issues (especially if more then one shark is present), etc...
It is definitely recommendable to leave the water asap, BUT in a calm and orderly fashion !!!!
A panicked human being will send signals that get the sharks even more interested !!! And that is - quite clearly - the last thing anybody needs in that situation...
And that is also the most important thing that needs to be explained to divers entering the water before a potential encounter with Oceanic whitetip sharks (or any other shark species for that matter): If you are not sure that you can stay calm in the face of an approaching shark, do not go inside !!! Or stay close to the reef and thereby avoid the close encounter with the Oceanics. Any other shark species is so much more reluctant to be close to humans, that there is generally no issues with them...
To keep on following these developments, I am inviting you to help me with my research on the oceanic whitetip sharks!
All it takes is for you to send me underwater photographs or video clips of your encounters with them. I can use them for my identification study, as long as you include the information on where (which reef) and when (which date) the footage was taken.
You find all these details and contact information on my webpage (www.longimanus.info), I would really appreciate your help ! The more we learn about these sharks, the better we can counter false accusations and hysteria, that can only be detrimental for them...
Best wishes and happy diving to all of you !!!!
