The docks are well-known for moon jellyfish, the UK’s most common species, which float with the movement of the water.
According to the Wildlife Trust, they are around the size of a plate and are recognisable by the four circles visible through the translucent white bell.
However, there is no need to worry as moon jellyfish don't sting humans.
