Every name, resolved

A pygmy sunfish is known by a current scientific binomial under the Catalog of Fishes and by an established English common name — “banded”, “Everglades”, “Okefenokee”, “bluebarred”, “spring”. The names are steadier than in most families, but not fixed: the Gulf Coast pygmy sunfish travelled under okefenokee until 2009, and the whole genus is still casually — and wrongly — lumped with the true sunfishes. This index cross-references both layers — the 7 scientific names and 7 common names — and resolves each one to its species page.
