Residents on the Isle of Man are being told not to worry about parts of the sea around the coast appearing red.

Particularly at Douglas, Laxey and Ramsey bays a natural phenomenon is occuring, called 'noctiluca scintillans'.

Scientists at the IOM Government Laboratory, operated by the Department of Environment, Food and Agriculture, have analysed samples and confirmed the discolouration is caused by a type of algae.

Whilst non-toxic, it is possible that dense blooms will also congregate other organisms such as jellyfish which will feed on noctiluca.

The public are therefore advised to avoid swimming through patches of water that are clearly discoloured.
