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 — Merriam-Webster See also OneLook
Encyclopedia
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

Science
Ichthyology, also called fish science, is the branch of zoology devoted to the study of fish, including jawless fish (Agnatha), cartilaginous fish (Chondrichthyes) and bony fish (Osteichthyes). According to FishBase, 33,400 species of fish had been described as of October 2016, with approximately 250 new species described each year. — Wikipedia

- Shark face study uncovers 400-million-year-old...on May 11, 2026 at 9:20 pm
Most of what scientists know about face development comes from studies in bony vertebrates such as mice, chickens, and zebrafish. However, their evolutionary counterparts, cartilaginous fishes, have remained largely unexplored. This gap has limited our understanding of how facial structures evolved at the origin of jawed vertebrates.
- One fifth of flowering plant evolutionary history...on May 8, 2026 at 1:20 pm
In a new study published in the journal Science, researchers from the Royal Botanic Gardens, Kew, ZSL (Zoological Society of London) and their international collaborators including Boise State University present the first global assessment of risk to the angiosperm (flowering plants) tree of life, warning that more than a fifth of all angiosperm evolutionary history is at risk of extinction.
- A skull full of surprises: Discovering the...on May 5, 2026 at 11:10 pm
A new study in Proceedings of the Royal Society B reveals the surprising neurological landscape of fish brains. Harvard researchers map the internal structures of ray-finned fishes' brains in 3D detail, discovering brain size and shape, as well as the endocasts, vary far more than expected.

Not many scientific studies sound like a Bond film, but ours really does involve lasers, sharks and doctors (of research, not the evil kind).

The first study to measure the full economic value of bottom trawling in Europe's waters calculates that the destructive fishing practice imposes up to €16 billion annually in net costs to society. The research is published in the journal Ocean & Coastal Management.
