Eschmeyer's Catalog of Fishes
The authoritative database of fish names, kept by the California Academy of Sciences, that records every valid species and genus.
Also: Catalog of Fishes
The Catalog of Fishes was begun by the American ichthyologist William Eschmeyer and is kept by the California Academy of Sciences in San Francisco. It lists every fish name ever published, the original description, where the type specimen is kept, and whether the name is still valid. Taxonomists use it to check whether a fish is truly new before naming it, and FishBase follows it for names. Its running count of valid species is the figure most often quoted for how many fish there are.
