This is Willie, the harbour seal from Sylt

Willie, short for Wilhelmine, is a famous seal that regularly visits the harbour of Hoernum on the island Sylt in northern Germany. She is feral, but she knows where to get easy fish. Tourists love her and a fish and chips stand at the harbour sells raw fish for tourists to feed her. Many stand at the edge of the harbour, calling her name until she appears. If you hold the fish out of the water, she will stretch up and bounce like a buoy to get to the fish. She is a magnificent creature, a grey seal. This footage was recorded back in September 2012.
