What are some interesting facts about cuttlefish?
Interesting Facts About the Cuttlefish 1 Weird Eyes – Unlike humans and many other animals, which have round pupils, cuttlefish have “W” shaped pupils. Their odd eyes are unique because they have no blind spots at all. These cephalopods can see in objects front of them, and objects behind them, at the same time. 2 Cuttlebone – While fish have a swim bladder, and sharks have an oil-filled liver, cuttlefish have a different way to remain buoyant in the water. They use a porous structure, conveniently called a cuttlebone, to stay neutrally buoyant. This allows them to “float” in place in the water, without sinking or rising. No other animal, not even other cephalopods, have the same structure. 3 Safe to Eat? – Before chowing down on, or playing with, any cuttlefish you find, it is important to remember that some species can be dangerous. A few species have toxic venom, and when they bite you it can make you very sick. One species has highly toxic poison in its muscles, which can kill you if you eat it! 4 Colorfish – Like other cephalopods, these species have the ability to change the color of their skin. Their pores contain sacs called chromatophores that have different colored pigments inside. They use these chromatophores to change colors, and even produce color patterns or flashes across the skin.

Most species live in shallow waters, but some species will range as far as 2,000 ft. beneath the surface of the water. Different species live in seagrass beds, coral reefs, rocky outcrops, ...
What is the difference between a cuttlefish and a shark?
Cuttlebone – While fish have a swim bladder, and sharks have an oil-filled liver, cuttlefish have a different way to remain buoyant in the water. They use a porous structure, conveniently called a cuttlebone, to stay neutrally buoyant. This allows them to “float” in place in the water, without sinking or rising.

What class is a cuttlefish?
For the card game, see Cuttle. 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, which is used for control of buoyancy .
What is the cuttlebone made of?
Cuttlefish possess an internal structure called the cuttlebone, which is porous and is made of aragonite. The pores provide it with buoyancy, which the cuttlefish regulates by changing the gas-to-liquid ratio in the chambered cuttlebone via the ventral siphuncle. Each species ' cuttlebone has a distinct shape, size, and pattern of ridges or texture. The cuttlebone is unique to cuttlefish, and is one of the features that distinguish them from their squid relatives.
How many arms does a cuttlefish have?
Cuttlefish have eight arms and two additional elongated tentacles that are used to grasp prey. The elongated tentacles and mantle cavity serve as defense mechanisms; when approached by a predator, the cuttlefish can suck water into its mantle cavity and spread its arms in order to appear larger than normal.
Why are cuttlefish called chameleons?
As with real chameleons, cuttlefish are sometimes referred to as the " chameleons of the sea" because of their ability to rapidly alter their skin color – this can occur within one second. Cuttlefish change color and pattern (including the polarization of the reflected light waves), and the shape of the skin to communicate to other cuttlefish, to camouflage themselves, and as a deimatic display to warn off potential predators. Under some circumstances, cuttlefish can be trained to change color in response to stimuli, thereby indicating their color changing is not completely innate.
Why do cuttlefish have blood?
The blood of a cuttlefish is an unusual shade of green-blue, because it uses the copper-containing protein haemocyanin to carry oxygen instead of the red, iron-containing protein haemoglobin found in vertebrates' blood. The blood is pumped by three separate hearts: two branchial hearts pump blood to the cuttlefish's pair of gills (one heart for each), and the third pumps blood around the rest of the body. Cuttlefish blood must flow more rapidly than that of most other animals because haemocyanin carries substantially less oxygen than haemoglobin. Unlike most other mollusks, cephalopods like cuttlefish have a closed circulatory system.
How big are cuttlefish?

The bite introduces a toxin, to quickly immobilise any troublesome prey .

How do cuttlefish move?
Cuttlefish have a fin fringe running along their sides. By undulating these fins cuttlefish are able to hover, crawl and swim. They can also move by ‘jet propulsion’, which can be an effective escape mechanism. This is achieved by assuming a streamline body shape and quickly squeezing water from a cavity in their body, through a funnel-like siphon which thrusts them backwards.
Why do cuttlefish produce clouds of ink?

How do cuttlefish control buoyancy?
Cuttlefish control buoyancy using an internal shell called the cuttlebone. By adding different amounts of liquid or gas into tiny holes within this structure, these animals can change their buoyancy, making them float up or down. They can also move using jet propulsion: filling their body cavities with water then forcefully squirting it out to propel themselves backward.

Overview
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, which is used for control of buoyancy.

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…
