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.
