Cleaner wrasse operate permanent cleaning stations on the lagoon bommies, advertising their services with a distinctive undulating dance that signals safety to visiting fish who suspend normal predator-avoidance to present themselves for parasite removal. The ecological importance of these tiny fish is immense — experimental removal of cleaner wrasse from reefs causes rapid declines in fish health, diversity, and abundance, demonstrating that cleaning stations underpin the entire reef fish community.

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.
