The encrusting sponge community that grows between clam clusters provides rich habitat for dorid nudibranchs, with Chromodoris willani and related species found on virtually every dive at Nu'usefata. These molluscs sequester toxins from the sponges they eat, making their vivid warning coloration honest advertising of unpalatability to predatory reef fish.

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.
