Etymology: Rajiformes is a Latin-derived scientific name for an order of cartilaginous fishes, and its core is the Latin "raja," meaning "skate," a word that was used for these flat, ray-winged fish long before any taxonomist applied it to a group. The "-iformes" ending is a modern taxonomic suffix built from Latin "forma," "shape," so the name literally means "skate-shaped." Such names were coined in the 18th and 19th centuries, when naturalists began sorting fishes into formal orders, rather than being inherited from ancient Greek or Roman usage. The suffix is the standard marker for animal orders in zoological nomenclature, which is why you will see parallel names like Carcharhiniformes (ground sharks) or Perciformes. The ending tells a reader at a glance that the word names a rank above family, and the stem tells them which animal anchors the group. Here the stem is "raja," so the order is organized around the skates and rays.

Synonyms: skates, ray fishes
