NORTHUMBERLAND beach goers and sea users are being urged to take part in a national survey about jellyfish.
Fascinating to some and frightening to most, jellyfish numbers appear to be on the increase in UK seas.
The Marine Conservation Society (MCS) aims to understand more about where and when they occur around the UK though.
While encouraging beach lovers and coastline visitors to report their findings, the organisation also warns to ‘look but not touch’ as some jellyfish can sting – particularly the lion’s mane.
The full-colour MCS jellyfish photo-ID guide can be downloaded from www.mcsuk.org
People can also visit the website to report jellyfish encounters in detail.
