UK Seas

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.


Porphyra umbilicalis




Rather flat and decidedly purplish in colour, this forms a slippery sheet on rocks when exposed to air by the tide.

It doesn’t look very appetising, but is commonly eaten. Carrageen is used as a common gelling agent in foodstuffs, and laver is a popular food in itself. Cooked with vegetables or bacon, and seasoned, it makes great eating as “laverbread” or other foods. Dried, it is highly regarded in Japan and called “nori”, often used to wrap food in edible parcels, or as a seasoning.
