In particular the most Western point, Brittany, is the perfect place for muck diving. Especially in the shallow bays of the estuary. In some places the bottom is littert with rocks of all sizes; some as big as cars others the size of peas. Some places are overgrown with seagrass where you can find lots of juvenile wrasses, sea bream, sea bass and cuttlefish who lay there eggs on the seagrass. Here you can also find pipefish and seahorses. On the rocks you find all sorts of life forms from sponges an anemones to little shrimps that use them for living in. All sorts of nudibranches that feed on the algae and hydro polyps. Sea urchins, starfish, shellfish and all sorts of fish from sharks and rays to the smallest blennies.
