Exploring and making use of the world’s marine resources is the focus of marine or aquatic biotechnology, sometimes known as “blue biotechnology.” For many years, aquatic or marine life has been fascinating and a source of subsistence. Oceans and aquatic systems are home to about 75–80% of all known living forms since a large portion of the world is covered by water. It examines the enormous variety in the physiology and structure of marine species. They are distinctive in their own ways and lack a land-based counterpart.
