Exotic crabs in waterway invasion
View at BBC NEWS
An exotic Chinese crab that preys on British native species is on the verge of taking over the country's major waterways, environmental experts warn.
Mitten crabs were first brought into Europe in ships' ballast water.
The UK spread has been most marked northwards to the River Tyne and on the south coast westwards to the Teign.
A study by researchers at Newcastle University compared their invasion to that of grey squirrels, which pushed native reds to the verge of extinction.
