Is Octopus Ink Similar to Fountain Pen Ink?
Topic: Pens, Pencils
Is Octopus Ink Similar to Fountain Pen Ink? -- "The ink of the octopus, or any cephalopod, is composed of highly concentrated melanin. This is the same dark pigment that we humans have, and which is responsible for skin color and the color of dark hair. It is a natural dye that cephalopods manufacture in an ink sac. Most, but not all octopuses have an ink sac and produce ink, but a few, such as the deep-sea octopuses, have lost this ability." Read more at His Nibs (Image from Cephalopods - a World Guide)
