Did you spot a jellyfish on a beach of the Mediterranean or Black Sea? We need your help! The jellyfish phenomenon is spreading across our seas and scientists don't have the tools for determining patterns of distribution because... they're here today, gone tomorrow.
Give scientists a hand by joining them by submitting a record of your sighting of jellyfish as part of the PERSEUS Jellyfish Spotting Campaign.
