sanguinolentus

Sanguinolentus is a Latin-derived term used in biological nomenclature as an adjective that appears in some species' scientific names. Etymology and meaning: from sanguis ('blood') and lentus ('full of' or 'stained'), the word conveys 'blood-stained' or 'bloody.' In taxonomy it commonly signals a red coloration, a blood-red pigment, or a historic association with blood, though the exact sense varies by genus. Sanguinolentus is not a standalone genus; rather, it is used as a specific epithet in species across diverse groups such as plants, fungi, and animals. The epithet's use reflects descriptive observation by the original describers and is subject to Latin grammatical agreement with the genus name, often producing masculine, feminine, or neuter endings. There is no single taxon named sanguinolentus; rather, it appears in multiple species names over history. See also: Latin binomial nomenclature, taxonomic epithets, ICZN.
