The breathing organs of fish, which are removed during processing since they decompose rapidly and may contaminate the fish.

The filamentous respiratory organs of fishes. Sharks have from 5 to 7 pairs of gills and most species must swim continuously to enable enough water to pass over the gills for the shark to get sufficient oxygen.
Gills are the respiratory organs of aquatic animals. They are specialized thin-walled regions of the body surface through which dissolved oxygen is taken into the blood and carbon dioxide released into the water. The gills of fish lie in gill slits on each side of the gullet. The gills of molluscs and fanworms have hair-like cilia that trap food pa...Gills are a respiratory organ found in animals which obtain oxygen from water, such as crustaceans, molluscs, fish and amphibians.
