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

Introduction

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 4400+ 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 258 species of cave and groundwater fishes, 41 species of interstitial fishes and 46 species with troglomorphic features from non-subterranean habitats (total 345 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.
