invasion – Giant oysters

Giant oyster specimens have been found on Germany’s North Sea island of Sylt. Marine biologists are unanimous in their explanation for the causes of the Pacific oyster invasion.

“Cold winters can bring the spread of wild oysters to a halt, but warm winters enable the oyster larvae to flourish,” said a marine biologist with Sylt’s Alfred-Wegener Polar and Marine Research Institute. “Their increase is a direct result of global warming.”, 8 Mar 2008
