Sepia is a genus of cuttlefish in the family Sepiidae encompassing some of the best known and most common species. The cuttlebone is ellipsoid in shape. The name of the genus is the Latinised form of the Ancient Greek σηπία (sēpía) "cuttlefish".
Cuttlefish possess up to millions of chromatophores, each of which can be expanded and contracted to produce local changes in skin contrast. By controlling these chromatophores, cuttlefish can transform their appearance in a fraction of a second. They use camouflage to hunt, to avoid predators, but also to communicate.
No creature on the planet can change its camouflage as fast and effectively as an octopus, cuttlefish or squid. These speed merchants of adaptive coloration can change their skin's color, brightness, contrast and pattern in as little as 200 milliseconds - one-fifth of one second - as fast as a human eyeblink.
