Schools of electric-blue tang surgeonfish graze the algae-covered reef top at Molly Beday in synchronised waves, their grazing keeping the coral structures clear of smothering algae growth. Juveniles transition through vivid yellow and bicoloured phases visible among the adult schools.

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.
