Long-snouted Seahorse

Hippocampus guttulatus

Sighting evidence at Sveti Nikola Island, Montenegro

Montenegro hosts one of the Adriatic's healthiest long-snouted seahorse populations, clinging to posidonia seagrass and algae in the 5 to 12 metre shallows around Sveti Nikola's eastern flats. Males brood eggs in a ventral pouch and can be observed at the same anchor points for months, making this a reliable macro subject for patient photographers. They feed by ambushing small crustaceans, pivoting their fused snout with explosive speed.

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.
