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 5300+ entries (1436 - date) is also provided.

There are also two secondary aims: One is to provide checklists and species accounts for the interstitial fishes and for troglomorphic fishes from non-subterranean habitats. The second is to provide a checklist and species accounts for the other obligate-subterranean vertebrates, which are all Amphibia. This second aim is work in progress and species accounts will appear in due course.

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 290 species of cave and groundwater fishes, 53 species of interstitial fishes, 49 species with troglomorphic features from non-subterranean habitats (392 fishes) and 15 troglobitic Amphibia (total 407 obligate subterranean vertebrates).

Recent additions

Reier et al (2022) is probably the most important recent paper on the fishes in the Dinaric karst.

Triplophysa qini new from China (Deng et al. 2022)

Panjio pathala new from India (Sundar et al. 2022)

Some major additions to the account for Troglocobitis starostini

Aenigmachanna mahabali is a synonym of Aenigmachanna gollum (Raghavan et al. 2022)

Probably the most important paper yet published on the conservation of subterranean habitats.

Luciogobius yubai added to interstitial fishes list.

I overlooked an important Symposium of the evolution of eye loss (Porter and Sumner-Rooney (2018): Evolution in the Dark: Unifying our Understanding of Eye Loss) from 2018. Papers from it were published in Integrative and Comparative Biology 58 (2018). All citations are now in the bibliography and you can find all ten of them by using a key-word search of Eye Loss Symposium.

With the addition of all papers that were presented at the 2022 AIM Meeting the number of references in the bibliography relating to cave Astyanax has reached 1000. The total for all subterranean and other troglomorphic fishes is 5080, so this represents ~20% of all known sources.

Important paper on subterranean speciation (it's on beetles but is very important)

New book on the genus Sinocyclocheilus available from April 2021. Link to buying a copy

Excellent presentation by Professor Daphne Soares on The Secret Lives of Cavefishes
