Mediterranean sharks and ray species at risk of extinction

Over half of the Mediterranean's shark and ray species are at risk of extinction, the International Union for Conservation of Nature (IUCN) said Monday, blaming over fishing for plummeting numbers.

Of the 72 known species of sharks and rays that exist in the Mediterranean, 39 face "an elevated risk of extinction", the conservation group said in a report released in Spain.

Twenty species, 12 shark species and eight ray species, are "critically endangered", or one step away from extinction, according to the report.

Species listed as "critically endangered" included the smooth hammerhead shark, the great white shark and the blue shark.

The Geneva-based IUCN said the conservation status of 11 species of sharks and rays in the Mediterranean had worsened since it issued its last assessment in 2007.

Over the past half-century 13 species of sharks and rays have become extinct in various spots of the Mediterranean due to over fishing, it added.

Local extinctions have been more prevalent in the waters of Spain, France and Italy as well as in northwest African countries and nations bordering the Adriatic Sea.
