Mangrove Snapper

Lutjanus argentimaculatus

Sighting evidence at Tori-Ike Connected Lakes, Miyako Islands

Mangrove snappers use the lake's sheltered shoreline as nursery habitat, juveniles threading through the prop roots of red mangroves that fringe the water's edge. Adults patrol the open water near the chemocline boundary, exploiting the elevated prey density that aggregates at the oxygen transition zone. The enclosed lake supports a self-sustaining population disconnected from the open reef community outside.

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.
