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.

The most important of these newly discovered motifs are boats with elk-head stems. This is the first time that these kinds of boats have been documented in southern or western Scandinavia and these motifs […]
