Overview

Cluster of volcanic boulders with tunnels and arches forming an underwater maze. Resident green turtles, frequent spinner dolphin passes, and excellent macro in the cracks. Calmer conditions than Sapata make it accessible to less experienced divers.

How we summarise this

We aggregate confirmed occurrence records from GBIF and OBIS within a fixed radius of each dive site. Occurrence records confirm presence and reveal seasonality clustering, but they DO NOT measure per-dive probability — there is no eligible-effort denominator. We deliberately do not publish a numeric '% chance of sighting' from this data.
