Common octopus are abundant among the rocks and posidonia rubble, hunting crabs and bivalves at dawn and dusk. Their jet-ink defense and rapid colour-change make close-up encounters endlessly rewarding for underwater photographers.

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.
