Every name, resolved

A loach carries a current scientific binomial under the Catalog of Fishes and, usually, an English common name — “clown loach”, “yoyo loach”, “kuhli loach”, “dojo”, “hillstream loach”. Cobitoidea has been heavily reshuffled — the old catch-all Botia split into Chromobotia, Yasuhikotakia and kin, the kuhlis moved from Acanthophthalmus to Pangio, and many stone loaches still travel under Nemacheilus — so the same fish often carries more than one name. This index cross-references both layers — the 1,405 scientific names and 628 common names — and resolves each one to its species page.
