Discover the wonderful sea creatures that inhabit the UK seas and shores

Know the name of the creature you are looking for?

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.

Egg wrack

Ascophyllum nodosum




An olive brown necklace of egg-like beads. The “eggs” are capsules of air (to help the weed float towards sunlight when the tide is in) or filled with a gooey liquid containing reproductive spores.

Sheltered Scottish sealochs are home to a variety of eggwrack that floats unattached to the seabed.


All UK rocky shores.
