cuttlefish : any of various marine cephalopod mollusks (order Sepioidea, especially genus Sepia) having eight short arms and two usually longer tentacles and differing from the related squid in having a calcified internal shell — Merriam-Webster   See also   OneLook


Cuttlefish or cuttles are marine molluscs of the order Sepiida. They belong to the class Cephalopoda, which also includes squid, octopuses, and nautiluses. Cuttlefish have a unique internal shell, the cuttlebone. Cuttlefish also have large, W-shaped pupils, eight arms, and two tentacles furnished with denticulated suckers, with which they secure their prey. They range in size from 15 to 25 cm (6 to 10 in), with the largest species, Sepia apama, reaching 50 cm (20 in) in mantle length and over 10.5 kg (23 lb) in mass. — Wikipedia

    Shape and color changing are key survival traits for many animals. Chameleons can change their body to hide from predators, to reflect their moods, or even to defend their territory, while some soft-bodied animal-like octopuses, squids, and cuttlefish can change both their color and shape to signal or camouflage.
