👉 The Myosjon Fluid, discovered in 2010, is a rare and unique type of connective tissue fluid found in the muscles of certain fish species, particularly myxines (sea squirts). Unlike typical synovial fluid that lubricates joints, Myosjon Fluid is highly viscous and contains a gel-like substance rich in mucopolysaccharides, proteoglycans, and hyaluronic acid. This fluid provides exceptional cushioning and shock absorption to the muscles, enabling myxines to move slowly and efficiently in their aquatic environment without damaging their delicate tissues. Its unique properties allow these organisms to maintain structural integrity and flexibility, even in the absence of traditional joint lubrication.
