List of Fishes of the Galapagos Archipelago, Ecuador (Version 3.0)

In preparation for the revised new edition of the 1997 book “The Fishes of the Galapagos Islands” by Jack Stein Grove and Robert J. Lavenberg, to be published by the EPCA, the East Pacific Corridor Alliance Foundation (www.epcafoundation.org), we have been reviewing literature and museum records and obtaining additional underwater photographs and specimens of fishes from Galapagos waters. Our Version 2.0 of the species list in Victor et al. (2024) added a number of cryptobenthic species, new records, and unresolved taxa, many documented from the expedition sponsored by the EPCA in May 2024, which included widespread surveys, intensive underwater photography, and collecting of tissues for DNA sequencing. We update the fish species list here, adding mostly deeper or mesopelagic species, but also clarifying and correcting a number of species in the prior lists, applying strict scientific criteria (Grove et al. 2022, Victor et al. 2024). The addition of deeper and mesopelagic species is based on a detailed review of collections at the Scripps Institution of Oceanography’s Marine Vertebrate Collection (SIO), where collections from the extensive EASTROPAC offshore oceanic trawl surveys are housed and where original collection notes are preserved, many available online (at https://sioapps.ucsd.edu/collections/mv/).
