The phenomenon of sharks gathering in the warm waters during the winter on the coasts of Israel - Hadera, Ashdod and Ashkelon - is a unique and intriguing phenomenon that does not occur in other similar places in the world
Just before the big storm and after six seasons of monitoring sharks in the warm water outlet of the Orot Rabin power plant on the shores of Hadera, a team of researchers from the Maurice Kahn Marine Research Station from the School of Marine Sciences at the University of Haifa identified and tagged a fin shark for the first time yesterday. "To date we have tagged 19 male fin sharks in six research seasons in Hadera and yesterday for the first time as part of our research we tagged a female fin shark. The flipper had a pattern of dots and that's why we chose the name "Freckles" for her, said Dr. Aviad Sheinin, Head of the Super Carnivore Department at the Maurice Kahn Marine Research Station of the University of Haifa.
As researchers at the University of Haifa have published in recent years, the phenomenon of sharks gathering in the warm waters during the winter on the coasts of Israel - Hadera, Ashdod and Ashkelon - is a unique and intriguing phenomenon that does not occur in other similar places in the world. So far, the researchers have observed two species of sharks in Hadera: thresher (female) sharks and finner (male) sharks. So the shark "Freckles" is the first finner that the researchers were able to identify and tag in Hadera and now they are interested in checking whether there are more leeks, or indeed the appearance of finners is rare among the sharks that gather off the coast of Hadera. If indeed these are rare appearances, the researchers will of course try to understand why this happens.
The finner sharks are in danger of extinction
"The fin sharks are in danger of extinction in the Mediterranean Sea and it is a pleasure to study them in Israel as part of a long-term ecological study on shark populations, from the DNA level, blood parameters, their bacterial community, reproductive status and more. The freckled leek received an acoustic tag that allows us to examine its movement along Israel's coasts and check whether it will return to this area in the coming years and whether its presence in the area is an unusual phenomenon," said Dr. Sheinin.

Interesting, except that once again the writers confuse species with type,
In the title it says: "Leek of the fin type",
and later referring to sex,
Anyone who deals with the subject knows that there is a difference
Between species and species and it is appropriate that in such an article
There will be no unnecessary confusion…
