Summary The lipid-rich pelagic teleost Maurolicus muelleri has large lipid depots located subcutaneously, intramuscularly and around the digestive tract. The lipid is contained within conventional adipocytes and is composed largely of triacylglycerols rich in 20:1 (n-9) and lipid-rich mesopelagic teleost Benthosema glaciale, except that the lipid is predominantly wax esters whose fatty alcohols and fatty acids are both rich in 20:1 (n-9) and 22:1 (n-11) moieties. An origin for the lipids of both species in the wax esters of calanoid copepods is indicated. The anatomical distribution of the lipids in these teleosts and their intracellular location point to their being fundamentally an energy store. The twin roles of neutral lipids in providing metabolic energy and buoyancy are discussed.
