The liver is a large and oily organ that comprises 25% of the total body weight of the shark. The two purposes of this organ in the shark are to store energy and oil. The liver is a hydrostatic organ. This organ helps with buoyancy since the liver stores oils, decreasing the density of the shark's body. The shark liver is also full of an oily-like substance called shark liver oil that helps the sharks be more buoyant and acts as an energy storer, where it can be utilized when needed.
