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.

How is this calculated?

Sighting evidence is compiled from iNaturalist observation records within a set proximity radius, filtered for quality-grade observations. “Last confirmed” is the date of the most recent research-grade record. Record count covers a rolling 24-month window. Confidence reflects record count, recency, and consistency of seasonal signal.
