Each species account begins with a genus page. Then the authors and their affiliations top each account page that includes name or names. These cover commonly used names, scientific names, the specific epithets and the vernacular names – meanings of which are explained for each poison frog species. "Taxonomic Comments" begin with the description or discovery of the species and discusses taxonomic placement and arrangement over time to the present understanding of this species relationships, and sister species are noted when known.

A section on Reproduction covers the mode used, how many eggs are laid, parental care, and larval deposition sites and diet when known. "Distribution" covers the species range, indicating if the species is endemic. "Threats" address pressures the species faces on a case-by-case basis. "Conservation Status" indicates the current IUCN Red List status and when deemed appropriate the authors suggest reassessment and present the justifications.
