gills
Fish breathing organs
Gills are the respiratory organs that allow fish and other aquatic animals to extract oxygen from water—rows of feathery or plate-like structures on either side of the head.
By extension, the thin radiating blades on the underside of a mushroom cap are also gills.
In informal speech, green around the gills describes someone looking nauseated or unwell.
