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

OneLook, Free Dictionary, Wiktionary, Urban Dictionary


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

    In a new study, an international research team led by Sebastian Stumpf from the University of Vienna describes an exceptionally well-preserved skeleton of the ancient shark Asteracanthus. This extremely rare fossil find comes from the famous Solnhofen limestones in Bavaria, which was formed in a tropical-subtropical lagoon landscape during the Late Jurassic, about 150 million years ago. The almost complete skeleton shows that Asteracanthus was two-and-a-half meters long in life, which makes […]

  • Future too warm for baby sharks
    on January 12, 2021 at 10:00 am

    New research has found as climate change causes the world's oceans to warm, baby sharks are born smaller, exhausted, undernourished and into environments that are already difficult for them to survive in.

    Living organisms have evolved mechanisms of biomineralization to build structurally ordered and environmentally adaptive composite materials. While research teams have significantly improved biomimetic mineralization research in the lab, it is still difficult to engineer mineralized composites with structural features and living components much like their native counterparts. In a new report now published on Nature Chemical Biology, Yanyi Wang and a research team in physics, advanced materials, […]
