Mediterranean Feather Star

Antedon mediterranea

Sighting evidence at Paleokastritsa Wall, Corfu

Feather stars cling to gorgonian branches and rocky projections on the wall, extending their delicate pinnules into the current to filter particles from the water column. They are mobile and will reposition themselves to optimise their feeding orientation in shifting conditions. Their crinoid arms — up to 15 centimetres long — harbour numerous commensal shrimp and small fish that are invisible until careful examination reveals them nestled in the pinnule bases.

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.
