Subterranean fishes of the world
Eidinemacheilus proudlovei Freyhof, Abdullah, Ararat, Ibrahim and Geiger 2016.


This web site is effectively the second edition of my book on the subterranean fishes of the world (Proudlove 2006). It follows very much the same structure and content and its main aim is to provide an always-up-to-date checklist of the cave and groundwater fishes of the world and detailed species accounts for all species. A fully searchable bibliography of 3800+ entries is also provided. A secondary aim is to provide checklists for the interstitial fishes and for troglomorphic fishes from non-subterranean habitats, and species accounts when time allows these to be prepared. One or two other lists and/or notes may appear if I find them of interest and relevance. Each species account has a Metadata link which takes you to a page describing the methods used, the notation and various other essential guides to using the site effectively.

There are currently 253 species of cave and groundwater fishes, 36 species of interstitial fishes and 45 species with troglomorphic features from non-subterranean habitats (total 334 species).

As of May 2018 the searchable bibliography is jointly authored by Graham Proudlove and William R. Elliott.

Important note:  It will take me while to get all of the species accounts fully populated. If you are interested in a particular species let me know and I'll prioritise it.

Recent additions

Very significant grant for biomedical Astyanax research

The worlds largest subterranean fish discovered in India and a press release of this.

The Sixth Astyanax International Meeting was held 17-20 March 2019. All meeting abstracts are now in the bibliography. To find all of them use Menu/Search the bibliography: Reference type = Conference paper, Year = 2019, Keyword = Astyanax International Meeting, Search type = Any word.

There are several new or upcoming books that are relevant:

Subterranean ecology edited by Moldovan, Kováč and Halse (2018)

The biology of caves and other subterranean habitats (Second edition) by Culver and Pipan (2019)

Encyclopedia of caves (Third edition) edited by White, Culver and Pipan (2019) includes chapters on cave fishes (Niemiler et al. 2019) and cave fishes in China (Ma et al. 2019)

And an important book on potential food supply for subterranean organisms:

Microbial life of cave systems edited by Engel (2015)

And several recently described subterranean fishes:

Triplophya erythraea from China.

Aenigmachanna gollum from India

Recently added is a list of review publications, to allow entry into the literature, for the two most studied subterranean fishes Astyanax jordani and Poecilia mexicana.

The various fish lists now have all species in a genus together after excellent work by my System Administrator Gary Douthwaite.
