Coconut octopus are common on the sandy substrate around the cave approach, where they cache shells and debris to construct portable shelters. They are highly intelligent and frequently interact with divers, sometimes pausing to observe before jetting away. Night dives around the cave entrance regularly reveal multiple individuals hunting along the reef edge.

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.
