How is cuttlefish ink made?
Cuttlefish ink was formerly an important dye, called sepia. To extract the sepia pigment from a cuttlefish (or squid), the ink sac is removed and dried then dissolved in a dilute alkali. The resulting solution is filtered to isolate the pigment, which is then precipitated with dilute hydrochloric acid. The isolated precipitate is the sepia pigment.

What is a cuttlebone?
Cuttlebone is an “internal shell” taken from a sea animal called a cuttlefish. The cuttlebones are made of about 85% calcium, containing air inside that helps with buoyancy. Cuttlefish are cephalopods, related to octopus and squid. Remarkably, cuttlefish are thought to be one of the most intelligent invertebrate animals.

Overview
Human uses
Cuttlefish are caught for food in the Mediterranean, East Asia, the English Channel, and elsewhere.
In East Asia, dried, shredded cuttlefish is a popular snack food. In the Qing Dynasty manual of Chinese gastronomy, the Suiyuan shidan, the roe of the cuttlefish, is considered a difficult-to-prepare, but sought-after delicacy.
Fossil record
The earliest fossils of cuttlefish are from the Cretaceous period. represented by Ceratisepia from the Late Maastrichtian-Paleocene. Whether the earlier Trachyteuthis is assigned to this order, or to the Octopodiformes, remains unclear.
Range and habitat
The family Sepiidae, which contains all cuttlefish, inhabits tropical and temperate ocean waters. They are mostly shallow-water animals, although they are known to go to depths of about 600 m (2,000 ft). They have an unusual biogeographic pattern; they are present along the coasts of East and South Asia, Western Europe, and the Mediterranean, as well as all coasts of Africa and Au…
Anatomy and physiology
Cuttlefish, like other cephalopods, have sophisticated eyes. The organogenesis and the final structure of the cephalopod eye fundamentally differ from those of vertebrates such as humans. Superficial similarities between cephalopod and vertebrate eyes are thought to be examples of convergent evolution. The cuttlefish pupil is a smoothly curving W-shape. Although cuttlefish cannot see …
Lifecycle
The lifespan of cuttlefish is typically around one to two years, depending on the species. They hatch from eggs fully developed, around 6 mm (1⁄4 in) long, reaching 25 mm (1 in) around the first two months. Before death, cuttlefish go through senescence when the cephalopod essentially deteriorates, or rots in place. Their eyesight begins to fail, which affects their ability to see, move, and hunt efficiently. Once this process begins, cuttlefish tend to not live long due to predation b…
Communication
Cephalopods are able to communicate visually using a diverse range of signals. To produce these signals, cephalopods can vary four types of communication element: chromatic (skin coloration), skin texture (e.g. rough or smooth), posture, and locomotion. Changes in body appearance such as these are sometimes called polyphenism. The common cuttlefish can display 34 chroma…
