The binomial name, family, and order of each species is available, as well as commonly-used synonyms and English, Spanish and French common names (when available). Information is also available on the taxonomic authority, which refers to the authors and date of the species description, and taxonomic notes, which (when present) clarifies difficult or confusing issues. Taxonomy follows the Catalog of Fishes, an online searchable database hosted by the California Academy of Sciences.
Comprehensive information on the geographic range (including depth), population size and trends (which includes detailed fisheries dependent or independent data where available), habitats and ecology, major threats, use and trade, and conservation measures are provided, along with relevant references. The area of occupancy (AOO) is typically based on the area of known habitat or the general depth distribution. The extent of occurrence (EOO) is based on a minimum convex polygon around the AOO.
The best available data for each species are compared to the quantitative thresholds for each criterion to assign a category of extinction risk. The category, criteria and detailed justification are presented, as well as information on the assessment itself (e.g., date, assessors, reviewers, etc.).
A generalized distribution map is available for each species, based on the known and inferred limits of the geographical range, and habitat and depth preferences.
Each species is coded against:
