Every name, resolved

A river stingray is known by a current scientific binomial under the Catalog of Fishes and, often, by a clutch of English and trade names — “motoro”, “black diamond”, “teacup ray”, “ceja”. Because river-stingray taxonomy is difficult — several species were long confused, and the trade coins its own names for colour forms — the same animal often travels under more than one name. This index cross-references both layers — the 43 scientific names and 62 common names — and resolves each one to its species page.
