Checklist of cave and groundwater fishes

This checklist covers all of the known troglobiotic (or stygobiotic) fishes. These live their whole lives in caves, which have relatively large conduit sizes, or in groundwater aquifers where the conduit size is often smaller. Both are habitats of total and continuous darkness and this leads, directly or indirectly (it depends on who you ask), to the suite of adaptations known as troglomorphy. The most obvious troglomorphisms are the reduction of eyes and of melanin pigment, both of which can regress to entire absence in some species. In addition to these regressive feature are a variable number of progress troglomorphisms, for example the elaboration of the mechanosensory lateral-line system. There are many sources which discuss troglomorphy in great detail but the folowing recent works are the best to begin with: Wilkens and Stecker (2017), Keene, Yoshizawa and McGaugh (2016), White and Culver (2012), Culver and Pipan (2009), Culver and Pipan (2014) and Wilkens, Culver and Humphreys (2000). A brief modern overview of the biology of subterranean fishes is provided by Borowsky (2018).
