This list's taxonomic treatment (designation and sequence of orders, families, and species) and nomenclature (common and scientific names) follow the conventions of Clements's 5th edition. The family accounts at the beginning of each heading reflects this taxonomy, as do the species counts found in each family account. Introduced and accidental species are included in the total counts for Slovenia.
