Cornetfish

Fistularia commersonii

Sighting evidence at Electric Beach, Oahu

Long, pipe-bodied cornetfish hover in mid-water near the discharge plume, shadow-hunting smaller fish by aligning their elongated forms with larger species to approach undetected. Their tubular snouts create a rapid vacuum strike that captures prey faster than the eye can follow, and their pale blue-green coloration provides near-perfect camouflage against the open water column.

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.
