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.

Sea trout

Salmo trutta morpha trutta




A striking trout, with a strong thick tail, and black or brown spots along its shiny flanks.

This is the same species as the brown trout, which is common in freshwater rivers, but grows bigger and bulkier in seawater.


The Dyfi estuary is renowned for its trout, and is popular with anglers.
