Discover the wonderful sea creatures that inhabit the UK seas and shores
UK seas is a guide to the fauna and flora found around UK coasts. While the majority of species are marine, some species are included that are regularly encountered on land by the coast, so you’ll find descriptions of non-marine species such as reptiles, amphibians, insects and plants as well.
Colour variable, but usually has pale umbrella-shaped bell with brown V-shaped markings, a little like the divisions on a compass. Possibly the most typical-looking jellyfish, with round bell-shaped body and long tentacles. Also called “sea nettle”, this jellyfish stings.
Sometimes found with a juvenile fish sheltering amongst its tentacles, apparently unharmed by its stings.
Found mainly to the west, but can appear anywhere.
