The elements comprising the coat of arms of San Marino include a shield featuring three mountains with three towers, each adorned with an ostrich feather weather vane. These towers symbolize the citadels of San Marino (La Guaita, La Cesta, and La Montale), while the hills represent the three summits of Monte Titano. The motto "LIBERTAS" in Latin, meaning freedom, is also part of the coat of arms.

Salmon is the common name for several species of ray-finned fish in the family Salmonidae. Typically, salmon are anadromous: they hatch in fresh water, migrate to the ocean, then return to fresh water to reproduce. Folklore has it that the fish return to the exact spot where they hatched to spawn. Tracking studies have shown this to be mostly true.
