Caulerpa (caulerpa lentillifera), commonly known as “sea grapes”, “green caviar”, “umi-budo”, is a single celled seaweed with amazing properties, which have been recently used successfully in the cosmetic industry. It has been named after small round offshoots, which burst like fish eggs under light pressure, not to mention its outward similarity with caviar of green color. “Green caviar” is a storehouse of mineral substances (magnesium, sodium, calcium), proteins and vitamins.
