Giant trevally hunt in coordinated groups through the channel, exploiting the strong tidal currents to ambush schooling fish compressed against the reef. They are highly site-faithful and frequently use the same ambush points across tidal cycles. Large individuals weighing over 30 kilograms are regularly encountered at this site.

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.
