ray : any of an order (Rajiformes) of usually marine cartilaginous fishes (such as stingrays and skates) having the body flattened dorsoventrally, the eyes on the upper surface, and enlarged pectoral fins fused with the head — Webster
Ray is a superorder of cartilaginous fish scientifically known as Batoidea. They and their close relatives, the sharks, comprise the subclass Elasmobranchii. Rays are the largest group of cartilaginous fishes, with well over 600 species in 26 families. Rays are distinguished by their flattened bodies, enlarged pectoral fins that are fused to the head, and gill slits that are placed on their ventral surfaces. — Wikipedia

A recent paper on the effectiveness of Marine Protected Areas (MPAs) in northern Europe ("Elevated trawling inside protected areas undermines conservation outcomes in a global fishing hot spot") reveals that industrial-scale fishing – primarily the use of bottom-trawl fishing – is widespread in so-called protected areas that were established specifically to safeguard highly biodiverse marine and coastal habitats across the North Sea. We welcome this important and timely piece of […]

What began as a Dalhousie Ph.D. student's investigation into North Atlantic shark populations turned into an eye-opening discovery that shows a number of European Union-designated marine protected areas (MPAs) are falling short of protecting threatened biodiversity. The research will be published in Science this week (Dec. 21). […]
