Gaston is the name of a brown fur seal that lived in Prague Zoo in years 1991-2002. He became famous during the 2002 European floods when he escaped from the zoological garden, when the rising waters of the Vltava river flooded his tank at Prague zoo. He swam more than 300 km (190 mi) from Prague to Dresden (Germany) on rivers Vltava and Elbe. He was recaptured north of Dresden and subsequently died due to exhaustion and infection.
