"Killer Shrimp" found in Norfolk Broad
People using Barton Broad in Norfolk are being warned about the discovery of so-called "killer shrimps".
The non-native species Dikerogammarus villosus has been found in a small area of the Broad.
It poses no health risks to humans or pets but can have a devastating effect on the marine life of the Broad.
Sailors are being urged to wash down their boats and sailing equipment to prevent the shrimp from moving to other areas.
