Last month scientists released a study warning that one quarter of all sharks and rays are threatened with extinction.



The research, published in the open-access journal eLife on January 21, was the result of collaboration between 300 scientists from 64 countries. It concluded that overfishing is the biggest threat to the most number of species, noting that up to 73 million sharks are killed each year for their fins alone.



“Fins, in particular, have become one of the most valuable seafood commodities,” the authors write, “It is estimated that the fins of between 26 and 73 million individuals, worth US$400-550 million, are traded each year.”



The study found that large, shallow-dwelling species are most likely to be at risk, while five out of the seven most threatened chondrichthyan families are rays.



“Overall chondrichthyan extinction risk is substantially higher than for most other vertebrates, and only one-third of species are considered safe,” concluded the study.



Below are a set of pictures released in conjunction with the report, as well as images published separately by WildLifeRisk after an investigation into the Chinese whale shark trade.

Guitarfishes and wedgefishes are among the most threatened rays, due to the high value of their large fins. This Giant guitarfish (Rhynchobatus djiddensis) reaches over 3 metres long and is classified as Vulnerable by IUCN. Photograph credit — Matt D. Potenski

Shark finning technique where only a band of skin to keep the fin attached to the spine is retained and the remainder of the body discarded at sea. This method is aimed at circumventing legislation banning finning which states that the fins of the shark must be 'naturally attached' to the body.
