Plumose Anemone

Metridium senile

Sighting evidence at Agdenes Wreck, Trondheim Fjord

Plumose anemones form dense white and orange colonies on every hard surface of the Agdenes wreck, filtering the nutrient-rich fjord current. Their feathery tentacles create a living curtain effect unique to cold-water European diving. The wreck's constant current keeps them fully expanded, producing the spectacular 'anemone wall' aesthetic that defines Norwegian cold-water photography.
