Wadden Sea

They are also found in the Eastern Atlantic Ocean, for example in the UK, as well as in the North Sea's Wadden Sea (where they are the dominant large clam).

Many anomalously white coloured individuals have been confirmed, mostly in the North Atlantic, but also notably around Turkish and British coasts, and in the Wadden Sea, Bay of Fundy and around the coast of Cornwall.

Predation of blue mussels is greatest during the three weeks it spends as a planktonic larva.

After the closing of the Zuiderzee they were still found in the Wadden Sea until the 1960s.

In Denmark, they both breed and winter throughout much of the country, but in particular the Wadden Sea region attracts many white-tailed eagles, mostly immatures, from elsewhere in Denmark and neighbouring countries during the winter.

In another study in the Wadden Sea, females primarily ate lugworms and ragworms while males relied almost exclusively on mud shrimps.

Breeding on Novaya Zemlya, Dolgy Island, Kanin Peninsula, Yugorsky Peninsula and the Barents Sea coastline in the Russian Arctic, wintering in the Wadden Sea area in southwest Denmark, northwest Germany and the Netherlands.

Asian populations migrate to subtropical areas in winter, south to northern India and southern China, but this species is largely resident in Europe, apart Scandinavian and some eastern European populations which migrate southwest, and from movements to favoured late summer moulting grounds, such as the Wadden Sea on the north German coast.

Human activities such as dredging and trawling damage eelgrass meadows; practices used in scallop and mussel harvesting in the Wadden Sea have cleared much eelgrass from the sea bottom there.

European oyster once formed large beds in the region and was still present until a few decades ago, when extirpated due to a combination of disease and the continued spread of the invasive Pacific oyster, which now forms large beds in the Wadden Sea.

Larsen is the only other researcher to have identified Guillardia in the wild within the Wadden Sea in Denmark.

In temperate regions such as the Wadden Sea they have been found to change roost sites each week and their feeding range may be as much as 800 km2 (310 sq mi) during the course of a week.
