Eschmeyer's Catalog of Fishes - version of 5 October 2020 (Continually updated since the early 1980s, around the turn of the month.)

In this edition, we provide 252 new species in 2020. In 2019 there were 353 new species described.

We record 35,653 valid fish species, including 17,986 valid fish species with the tag ‘Habitat: freshwater’.

Updated Apr. 9, 2020 - Authors' Count of Species/Subspecies Descriptions. See how many species/subspecies each author has described. This list was previously posted as a list of "batting averages", comparing total number of species descriptions to number still considered valid. The "batting average" concept was originally conceived by Dr. Eschmeyer for our 2010 paper "Marine fish diversity: history of knowledge and discovery (Pisces)", and was meant to show differences between previous eras and the modern era. It was not meant to be a critique of any individuals, nor a measure of any individual's scientific acumen. The "batting average" concept having served its purpose, it's no longer relevant to present it. In addition, most individuals are only interested in the total number of new descriptions, which is what we present here. - Jon Fong

Family Group Names

We are making additions to:

Van der Laan, R., W. N. Eschmeyer & R. Fricke 2014 (11 Nov.), Family-group names of Recent fishes. Zootaxa Monograph 3882 (1), 1-230. DOI 10.11646/zootaxa.3882.1.1

Download the addenda to the family-group list as a PDF.

See Family Group Names for future updates by R. van der Laan.

Unavailable names

By default, search results will not include item 3 names -- unavailable names that detract from the main list of available names. These are mostly names mentioned in synonymy, names in lists, etc. They are still in the database, so if you want to see them, check the box labeled Include unavailable names before searching.

[Ron Fricke devoted much time to improving references and journals, many of which had not been examined in 15 to 25 years. Please remember that the title of a paper often differs in three places: the title on the paper itself, the contents listed by the journal, and in the PDF provided by the journal. Ron tends to follow the title on the pdf for recent papers and the title on the original for earlier publications. Many of our dates of publication are documented for priority purposes. Some current journals have a target date, but actual publication is often delayed. For nomenclatural date problems, we will help if we can.]

Please remember that if you got to Eschmeyer's Catalog of Fishes from Fishbase, you are NOT in Fishbase. Fishbase is a more comprehensive database for a different audience, but they use Eschmeyer's Catalog of Fishes information in their authority file.

Some other useful sites for fishes are (1) Fishbase [Fishbase team, Manila]; (2) www.stri.org/sftep -- A comprehensive database on Shorefishes of the Tropical Eastern Pacific (and of the Western Atlantic) [Ross Robertson]; (3) shark-references.com -- A database on elasmobranchs, with over 13,000 references, information on taxa, type specimens, etc. [Jürgen Pollerspöck]; (4) FishWisePro.com -- a comprehensive relational database of more than 99,350 scientific species name combinations and over 34,300 well-identified (mostly marine) fish pictures [Dennis Polack]; (5) Freshwater Fish List, 23rd edition December 2017 by Richard Van der Laan; (6) ETYFish Project (derivations of Fish Names) by Christopher Scharpf; and (7) BioStor, for Biodiversity Heritage Library references. A very useful site is Worldfish.de [not associated with Fishbase or Worldfish]. Maintained by Michal Mikšik and Erwin Schraml. They post new fish taxa and references as they are published.


A summary paper was published in 2010 from Eschmeyer's Catalog of Fishes database that might be of interest to users of the Catalog. "Marine fish diversity: history of knowledge and discovery (Pisces)." By William N. Eschmeyer, Ronald Fricke, Jon D. Fong & Dennis A. Polack. Zootaxa, no. 2525:19-50 (2 July 2010, open access, click title to download).

About 384 new species were described in 2014. As always, notifying us of missed original descriptions and errors in the database or providing PDFs of recent papers is most welcome.

Bill Eschmeyer edited type localities and standardized many place names. Our style is to use current place names found on an English map (or from Wikipedia and Google sites). Should you need original localities, they can be found in the original descriptions or from particular museum holdings (often online).

Many scientific names of fish species are based on personal names; some were found to be incorrect. For example, Jordan and co-workers spelled Japanese names ending in "a" with a terminal "e" as in matsubarae; that is acceptable, with the name Latinized first. So those names do not end in "i". Remarks are provided by Eschmeyer in this version for most species based on personal names. For a review of this very technical subject, see Dubois 2007: Zootaxa No. 1550:49-68.

New treatment of synonyms: Often an author revises a genus and treats a species in detail but does not mention the species synonyms (if any). If he/she does not mention the synonyms (rather common in recent treatments) and moves the valid “parent” species to a different genus, do we move the synonyms automatically, although the revising author may not have studied or assessed the synonyms? In the past, we did not move the synonyms. Typically, this often resulted in the synonyms being in a different current genus than the valid parent species. We now move the synonyms to the genus of the valid parent species, but no “status reference” showing the new generic placement is found with the synonym. Some synonyms will be moved incorrectly, but it is considered more desirable to have the potential synonyms in the same current genus as the valid parent species.

Some conventions used in Eschmeyer's Catalog

Author plus date and a species code: The code of Zoological Nomenclature does not require a comma between the author and date, only a suggestion. In fact, we consider that confusing as that is traditionally used to show a cited reference in journal publications and not a species authorship and date. Genus+species+author+date (with parentheses as needed) is a (nearly) unique code or formula to define every species [2 known exceptions]. So you will find no comma between the author and date. Some journals are now treating species in this way.

Figures: Under a new species heading, some journals list (a) only the major figure, some list (b) all figures (including maps, habitats and graphs), and (c) some give figures showing the full view and any illustrated parts of the species. We give all figures that show a full view and any anatomical part of the species, so our listing of figures often differs from the treatment by a journal in the original description (as listed in the species heading).

Type localities: We give a current place name that one will find on a Google search or in an “English” atlas. For some species described many years ago, one may find both the original locality and in parentheses a modern name for that locality. Many collections now have their holdings on-line, and it is there one can usually find the actual original locality if needed. Current localities are often augmented by additional information, such as coordinates.

Authors: We have added initials in brackets to distinguish all individual authors of genera and species.

Other sections

Species of Fishes by Family/Subfamily -- Total valid taxa reflect new taxa added minus taxa moved into synonymy plus taxa newly moved to valid. The classification is as used in the Catalog of Fishes. Prepared by Bill Eschmeyer and Jon Fong, with modifications by Richard van der Laan.

Family-Group Names -- Priority applies to Family-group names. It did not in early years. As classifications are refined with use of more subfamilies and tribes, it is required to use the oldest available family-group name for these new taxa.

Ichthyological Collections -- Presented are those specimen collections mentioned in the main Catalog of Fishes database, especially as repositories of type specimens. Besides museum names and abbreviations, this includes WWW sites, cross-referencing of abbreviations, and selection of museums by country, along with type catalogs, historical articles, name changes, transfers, and other items for individual collections. Prepared by Ron Fricke and Bill Eschmeyer.

Ichthyological Journals -- There are nearly 2600 individual journals or monograph series in the Catalog of Fishes database. We provide full citations, and other information such as changes in titles, published duration, ISSN numbers, WWW sites, etc. Prepared by Ron Fricke and Bill Eschmeyer.
