Odontesthes regia is a fish belonging to the family Atherinopsidae, commonly referred to in English as Chilean silverside,[2] Peruvian silverside[2] or sea silverside, and in Spanish as pejerrey[2] or pejerrey de mar.[2]

This is an epipelagic species distributed from the north Pacific coast of Peru to the Aysén Region, in Chile.[3] The species has great economic importance as a fresh staple food.[2] Although the family Atherinopsidae includes 104 species (13 genera), only 17 species have been cytogenetically studied to date; cytogenetic studies in this group are still scarce.[4]
