Every name, resolved

A knifefish is known by a current scientific binomial under the Catalog of Fishes and, often, by a clutch of English and trade names — “black ghost”, “glass knife”, “banded knife”, “electric eel”. Because these fish are cryptic, nocturnal and hard to tell apart — several species were long confused, and the trade coins its own names — the same animal often travels under more than one name. This index cross-references both layers — the 279 scientific names and 110 common names — and resolves each one to its species page.
