A small but growing colony of grey seals has recolonised the Cíes Islands, marking one of the southernmost breeding populations in Europe. Underwater, juveniles are famously curious and will approach divers closely, twisting and spiralling through the kelp in playful investigation before surfacing to breathe.

Grey Seal is listed as a curated species here based on historical reports.

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.
