Common Starfish

Echinaster sepositus

Sighting evidence at Ras el Aouah Reef, Djerba

Bright red starfish carpet the rocky terraces in densities that indicate a healthy benthic invertebrate community, feeding on encrusting organisms and detritus. Their abundance reflects the low anthropogenic disturbance on this reef compared with heavily visited Mediterranean sites. They serve as an important food source for large wrasse and certain benthic-feeding rays.

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.
