The sea bishop or bishop-fish is a legendary creature first recorded in the 16th century. According to legend, it was taken to the King of Poland, who wished to keep it. It was also shown to a group of Catholic bishops, to whom the bishop-fish gestured, appealing to be released. They granted its wish, at which point it made the sign of the cross and disappeared into the sea.
