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.


Chondrus crispus




Dark red, almost purple, with short fronds that quickly dry with an encrusting of salt when out of water. Plants growing high up the shore can be a pale green colour, like the one in the photograph.

One of the most commonly eaten seaweeds, found in a whole range of prepared foods - its “agar jelly” helps thicken desserts, especially icecream and milkshakes, as well as processed meat and beer!


All around the UK, except sandy east coasts.
