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.
