The Jellyfish Phenomenon of the Mersey Estuary
The Liverpool docks are well-known for moon jellyfish, the UK’s most common species, which float with the movement of the water. I am no expert but these that I have pictured at the nearby River Alt appear to be the same type. Aurelia aurita (the moon jelly, moon jellyfish, common jellyfish, or saucer jelly) is a widespread species,
All species in this genus are very closely related, and it's not that easy to identify Aurelia medusae for example without genetic sampling.
Year after years these guys float onto the beaches when the weather warms up. I was lucky enough to be on the estuary when the high tide had deposited a great many jellyfish.
Countless jellyfish were trapped in the tidal pools.
My son Jason had never seen so many jellyfish
Beaches absolutely littered with jellyfish this week
They are so unusual and create such public interest that I believe that they should have a blog page all of their own...
