The holders of squid ink are known as SACS, which is an acronym for 'Squid Ink Collectors'. These individuals are responsible for collecting and preserving squid ink, which is a valuable resource used in many industries. Squid ink is used in the production of food, cosmetics, pharmaceuticals, and other products. It is also used as a natural dye and has been used for centuries in traditional medicine. SACS are highly skilled professionals who must have a deep understanding of the biology and ecology of squid and their ink. They must also be knowledgeable about the various methods of collection and preservation of squid ink.
