A group of wildlife enthusiasts were looking forward to their lunch during an expedition to the Arctic island of Svalbard.
But they soon discovered a hungry polar bear was also rather keen to try their cauliflower soup.
The giant predator poked his head through the open porthole into the kitchen of the ship, which had weighed anchor so the passengers could enjoy the fabulous icy landscape.
