Comment on Debunking myths on Mediterranean great white sharks by Giuseppe Notarbartolo di Sciara

Thank you, I wasn’t aware of that episode, which should now be taken into account. However, one more attack during the last quarter of a century doesn’t really change greatly the soundness of my point.

0.2 attacks per year on average, the last of which occurred 23 years ago in the bay of Baratti (near Livorno, Italy).

False. Unless you are thinking of deadly attacks. On the 6st Septemter 2008 the Slovenian diver Damjak Pesek was attacked and fatally injured by a Great White of the shore of the remote island of Vis (Croatia). He was was spearfishing with friends and obviously carried dead fish on his body he speared before.

Good point! In fact, the research you mention (see full reference below) points to the likelihood that the GWS population in the Mediterranean is even more endangered than what it is normally considered to be.

The great whites in the Mediterranean are genetically distinct from the ones found in the Atlantic. DNA testing has confirmed that they are in fact Australian ‘migrants’; sharks that lost their way several thousand years ago and ended up in the Med. Here’s the link:

That said, I find some of Jonas’s points interesting. There may be some mixing occurring and if it benefits the survival of the species I’m sure a lot of conservationists will be glad! After all this is already happening among different blacktip species off Australia:

The Mediterranean population of Great whites is a distinct one isolated from the Atlantic one possibly half a million years ago. It is genetically closer to the Australian one and breeds in the Strait of Sicily. Atlantic male wanders contribution to the genetic pool seems uncertain, since the Mediterranean population variability looks too low.

There certainly can be movements of GWS to and from the Med across Gibraltar, however the myth I want to expose is that the Med is a “safe bathing area” which is only occasionally visited by GWS entering the Med through Gibraltar, perhaps following ships, as is quite often said and written in the popular press. The report from Morocco in your site is interesting and I thank you for bringing it to my attention.

Regarding Myth n. 1, Great Whites enter the Mediterranean from the Atlantic through the Gibraltar Strait” You may consider your statement, please see this link about White Shark probably heading for the Gibraltar Strait from the Atlantic: http://officetoocean.blogspot.se/2012/02/huge-great-white-caught-in-morocco.html

Comment on The scam of dolphin-assisted therapy by brigitte jones

I agree with the view it’s wrong to use dolphins in captivity. Furthermore, while some disabilities respond well to animals and water, that would not be the case with those who are truly autistic. They generally hate novelty and have no inclination to interact meaningfully with either humans or animals. Truly autistic persons are propelled by their condition to preferring instrumental objects or treating all living things as such. Autistic children’s progression is when they discover and retain that they need this human to do “X” so they can get “Y”. A need or desire to be fullfilled. This they do by treating the person, their object for enacting “X” like an instrument, via gestures pulling them , using limited words or sounds and possibly pointing. Autism is so much of an issue that any pipe dream is clung onto.
Born of desperation, resulting in improbable beliefs in solutions that are based on rare, odd improperly evaluated examples. Extremely twisted as “autistic children” are the supposed main beneficeries, the least likely ones to respond positively. Just shows how exploitative and unethical marketing for a profit can be.
