Abrolhos Chromis

Chromis multilineata

Sighting evidence at Parcel das Paredes, Abrolhos Banks

Dense schools of this endemic chromis hover above the chapeirão formations, feeding on plankton drifting in the nutrient-rich currents. Their iridescent bodies catch the slanting tropical light, creating shimmering curtains of silver and gold above the reef surface. As a species strongly associated with the chapeirão habitat type, they represent the tight ecological link between Abrolhos' unique geology and its marine biodiversity.

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.
