The sea lemon is one of Iceland's most conspicuous nudibranchs, its warty yellow-orange body reaching up to 7 cm and standing out vividly against the dark barnacle crust of the pilings. It feeds on sponges and can be found crawling across every available surface from the low tide zone down to the sandy floor. Egg ribbons in characteristic spiral shapes are found near adult individuals throughout spring and summer.

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.
