59 per cent of coral reef shark and ray species are threatened with extinction, an extinction risk almost double that of sharks and rays in general. Read more at straitstimes.com.
PARIS - Nearly two-thirds of the sharks and rays that live among the world’s corals are threatened with extinction, according to new research published on Tuesday, with a warning that this could further imperil precious reefs.
Shark and ray species - from apex predators to filter feeders - play an important role in these delicate ecosystems that “cannot be filled by other species”, said Dr Samantha Sherman of Simon Fraser University in Canada and the wildlife group TRAFFIC International. The authors found 59 per cent of coral reef shark and ray species are threatened with extinction, an extinction risk almost double that of sharks and rays in general.
“Many species that we thought of as common are declining at alarming rates and becoming more difficult to find in some places.”Sharks are under most threat in the Western Atlantic and parts of the Indian Ocean, whereas the Indian Ocean and South-east Asia are the highest risks for rays.
