Warnings for swimmers over poisonous fish
Bathers along Britain's coastline are being warned to be on the look out for the country's most poisonous fish.
Weever Fish are about 15cm long and have venomous spines along the dorsal fin.
They like shallow water and are so well camouflaged that many people do not see them until they have stepped on them.
The pain from the sting is described as excruciating, turning the foot red and swollen.
