The Galapagos Species Checklists were descriptive documents covering either a concrete taxonomic group or a group of species forming part of a specific analysis. Each checklist included a list of authors, a description of the taxonomic group or subject, and a list of species, downloadable as PDF and CSV.

This format was discontinued in 2018 and no new checklists have been produced since. The data reflects the knowledge available at the time of publication and is outdated. Up-to-date information on all species is available in the Galapagos Species Database.
