Cuttlefish arent very cuddly, and they arent fish, but they are amazing creatures. Cuttlefish can change the color and texture of their skin to camouflage themselves with their surroundings, dazzle their prey, and signal to other cuttlefish. Some species have a visual vocabulary of several dozen signals consisting of different color patterns. Cuttlefish also make their own ink, to cloud the waters and mask their escape from predators. Cuttlefish ink has been used in the past as writing ink, a stain for photographs (sepia-tone is named after the cuttlefish genus sepia) and even as an additive to pasta for extra flavor. If you want a modern sepia brown ink that doesnt make your homework smell like a mollusk, then get a bottle of Cuttlefish Brown from Anderillium inks.
