The sea-griffin (German: Fischgreif; Polish: rybogryf, gryf morski) is a heraldic charge in form of an aquatic griffin with the head, upper-half, wings, and talons of an eagle and the lower-half of a fish.
[1] The symbol originates from the region of Lands of Schlawe and Stolp in Pomerania, Central Europe.
It was used in the coat of arms of the Swienca family, which hold powerful offices in the area from 13th to 14th centuries.
Following them dying out in around 1316, the area went back under the direct rule of the House of Griffin, which continued to use the sea-griffin in the regional coat of arms.
[3][4] It was a white (silver) sea-griffin facing viewer's left and placed within a red field.
