SHARKS GOIN' DOWN IN MED-SEA
Really few attacks altough sharks usually live into the mediterranean sea from time immemorial.
Sharks are going to be extinted in the mediterranean in the next years if anybody do something...
In the Mediterranean there are 47 species of sharks, of which 20 are large predators at the apex of the food pyramid.
Bycatch in deep-sea fishing, fishing for sharks and direct human pressure on coastal areas the main causes of decline.
"The magnitude of the decline in Mediterranean shark - said Ferretti, a researcher at the 'Dalhousie University in Halifax, Canada - is such as to arouse serious concern at the effects this could have."
As Ferretti said: the decline in two centuries was about 97%, virtually "functionally extinct levels" with serious consequences for the entire mediterranean basin that is losing top predators in the food chain entering into short circuit!
DOCUMENTED SHARK ATTACKS ALONG ITALIAN COAST (since 1926)
