Barracuda aggregate in the pass in tornados of several hundred individuals, rotating slowly in the current just inside the reef crest at 10 to 20 metres. The behaviour is thought to be a schooling strategy linked to tidal timing, with the schools forming on incoming tides and dispersing to hunt individually on the outgoing flow. Their silver bodies catch the filtered light in flashing unison, creating one of the most visually spectacular schooling displays in the Indian Ocean.

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.
