1. Cephalopod - Wikipedia, The Free Encyclopedia
   There are around 786 distinct living species of cephalopods. Two important extinct taxa are Ammonoidea, the ammonites, and Belemnoidea, the belemnites.

   Extractions: Neocoleoidea (most living cephalopods) The cephalopods Greek plural (kephal³poda); "head-foot") are the mollusc class Cephalopoda characterized by bilateral body symmetry , a prominent head, and a modification of the mollusk foot, a muscular hydrostat , into the form of arms or tentacles Teuthology , a branch of malacology , is the study of cephalopods. The class contains two extant subclasses . In the Coleoidea , the mollusk shell has been internalized or is absent; this subclass includes the octopuses squid , and cuttlefish . In the Nautiloidea the shell remains; this subclass includes the

   Extractions: Under Construction Richard E. Young, Michael Vecchione, and Katharina M. Mangold (1922-2003) Containing group: Mollusca The Cephalopoda is an ancient and very successful group of the Mollusca. Cephalopods have been among the dominant large predators in the ocean at various times in geological history. Two groups of cephalopods exist today: The Nautiloidea with a few species of the pearly nautilus, and the Coleoidea, containing the squids, cuttlefishes, octopods and vampire squids, which is represented by about 700 species. Cephalopods are the most active of the molluscs and some squids rival fishes in their swimming speed. Although there are relatively few species of living cephalopods, they occupy a great variety of habitats in all of the world's oceans. Individual species are often very abundant and provide major targets for marine fisheries. Cephalopods first appeared about 500 million years ago in the Upper Cambrian Period. Although considerable uncertainity still exists, the two extant lineages may have separated 470 mya with the possible origin of the Bactritida or earlier. The long separation of the two lineages has, today, resulted in lineages with cephalopods that are very different in structure.

   Extractions: Octopus Movement NAUTILUS OCTOPUS Research on Cephalopods The cephalopods include the octopus, nautilus, squid and cuttlefish that are the most highly developed of all invertebrate groups. This class of molluscs have well developed nervous system, brain and eyes, with octopus being the subject of experiments where they successfully solved problems. Most cephalopods 'live hard and die young' having fast growth rates and only a 1-3 year life-span. There are hundreds of cephalopod species worldwide in all undersea habitats, and surprisingly few inhabiting the coral reefs. Dr Mark Norman and Andy Dunstan, head the Undersea Explorer cephalopod project - a non profit study of Australian cephalopods funded by the Gro-Sea Foundation. Dr Norman has studied cephalopods throughout the Western Pacific and has commented on how little the group is known to science. He's personally discovered more than 100 new species, 44 of them in Australia. This project aims to look at octopus species and cuttlefish along the northern Great Barrier Reefs and at Osprey Reef in the Coral Sea. Included in the overall cephalopod project is the ongoing study of the nautilus population in the depths of Osprey Reef - a capture-record-tag-release program has been underway for five years.

Fautin Kingdom: Animalia Phylum: Mollusca Class: Cephalopoda Members of this Class There are approximately 650 to 700 extant species of cephalopods in two subclasses and five orders. Cephalopods are strictly marine and are found in all of the world's oceans. All cephalopods are carnivorous. The strong beak is at the entrance to the buccal cavity , on the floor of which lies the radula. There are two pairs of salivary glands , one of which may be poisonous. The digestive tract consists of three parts: esophagus , which may contain a crop; stomach , which mashes food; and caecum , where most digestion and absorption occur. The posterior portion of the caecum contains a diverticulum that serves as an ink gland, producing a suspension of melanin that can be expelled through the mantle cavity. Locomotion in cephalopods is accomplished mainly by jet propulsion. To close its mantle completely, a squid fits two cartilaginous ridges on the mantle wall into two cartilaginous grooves on the opposite funnel wall; contraction of circular muscles around the mantle cavity then forces water out the funnel. The funnel can be aimed, allowing the animal to change its direction. Locomotion in other cephalopods can be accomplished by other means. Octopoids can use their arms to "walk," and sepioids and teuthoids possess lateral fins that can propel the animal.

    Extractions: Cephalopods usually have three hearts. Two hearts pump blood to the gills, and one central heart pumps oxygenated blood to the body. Cephalopod blood is blue because it binds oxygen using a blue, copper-containing protein called hemocyanin. Human blood is red because the oxygen-binding protein hemoglobin contains iron. Brain

    Extractions: In marine environments, cephalopods clearly rank at the top of the Protostomes, in terms of size, intellegence, and trophic dominance. At the top of the Deuterostomes are either the modern teleost fish or the marine mammals. For my purposes, I am going to use fish as the Deuterostome example, because they reflect a more primary adaptation to aquatic habitats, and occur in a wider range of sizes and habitats. (Competition between fish and marine mammals may be relevant to the more recent success of the teleosts, compared to other groups of fish, but that's a story for another day.) "The constraints on cephalopods: why squid aren't fish", R. K. O'Dor & D. M.Webber, Canadian Journal of Zoology, 64: 1591-1605 (1986). They summarize by saying: "Despite the functional similarities created by competition in the nekton, ... squid are no longer so much competing with fish as trying to stay out of their way."

13. Cephalopods In A Blanket, Educational Resources For K-16
    cephalopods in a Blanket, Educational Resources for K16, Kentucky Geological Survey.  
    http://www.uky.edu/KGS/education/ceph.htm
    
    Extractions: Cephalopods in a Blanket This recipe uses a variation of the old pigs-'n-a-blanket theme in order to make edible cephalopods. Cephalopods were squid-like animals that lived in shells. They were very common in Paleozoic-era seas. They would probably have tasted like calamari (a fancy name for squid to trick people into eating it), but what are your chances of getting a child to eat squid? You'll need: Preparation time: 30 to 45 minutes Recipe: 3. Bake in the oven according to the directions on the batter roll, usually until the dough is slightly golden. 4. Remove from the oven. If the "tentacles" haven't opened, open them up with a knife. 5. You can use your imagination for putting eyes on the cephalopod. The easiest way to do this is to place a drop of mustard on the side of the cephalopod first, and then put a dab of ketchup on a toothpick or the end of a fork, so as to place a smaller spot of red ketchup within the larger yellow circle of mustard. For regular-sized hot dogs, place the eye on the hot dog between the "tentacles" and the crescent-dough shell. For appetizer hot dogs there isn't enough room for the eye on the hot dog, so just put it on the crescent-dough shell. You can also slice an olive and pimento and attach with a dab of ketchup. 6. Eat and enjoy!

15. Polarized Signaling Underwater And The P-vision Of The Octopus
    As other cephalopods, they have chromatophores and iridescent cells forming special So, why is Pvision so prevalent in cephalopods? How do they do it?  
    http://polarization.com/octopus/octopus.html
    
    Extractions: Home Vikings Bees Rainbow ... Space Undercover Underwater The case for polarized communication Some cephalopods can change the polarization of the skin and may use it for stealthy signaling The underwater world is polarized and many of its inhabitants are aware of it. They have polarization vision (P-vision). But can any of them actively control the polarization of light and use it for signaling? Maybe so. Moody and Parriss discovered P-vision in octopuses and soon after others found it in the rest of the octopods and decapods (sweet words in the ears of a shoemaker). Indeed, if you have eight or ten arms and a big head you've probably got P-vision. Could it be the secret of how the Giant Squid avoids encounters with eager underwater photographers? Nobody has yet been able to study those creatures of Jules Verne's nightmares, but their smaller relatives are much more amenable for experimentation (and a favorite of neuroscientists). The European Cuttlefish (Sepia officinalis) is a relative of the squid with a calcified internal shell. They live in coastal waters throughout the Mediterranean Sea and eastern Atlantic from England to North Africa. They can be quite cute or cute-less, depending of the profile they show the camera (but beware of hurting their feelings: they may ink you), as seen in these photographs from the National Resource Center for Cephalopods , in Galveston, Texas.

16. Cephalopods
    All the recent cephalopod shells are composed of aragonitic layers prismatic layers, nacreous layers and spherulitic prismatic layers.  
    http://biomin.geol.u-psud.fr/ydweb/cephalo/index.htm
    
    Extractions: Cephalopods It must be noticed that the "prismatic" layers in Cephalopod shells are not similar to those of other Molluscs ; they are always aragonitic, and composed of small fibres, ressembling to the fibres of the coral skeletons. The outer layer of the outer wall is spherulitic prismatic in Nautilus and Sepia , and prismatic in Spirula . The nacreous middle layer is almost entirely organic in the Spirula shell, more or less mineralized in the Sepia shell. The inner layer is prismatic in the three genera. It may be supposed that the rostra of belemnites and other fossil Coleoids are hypertrophied outer spherulitic prismatic layers. Return to Studied material Last Updated on 2 October 1997 by Dauphin

Some of them lurked back in the rocks, others were closer to the front of the tank, but all of them were facing the same direction. Except for the undulations of their fins and the languid posturing of their tentacles, they were motionless. Their bodies rippled with changing color patterns.

    http://invertebrates.si.edu/cephalopods.htm
    
    Extractions: Can an octopus leave the water? Octopus, at least some species, on rare occasions reportedly can leave the water to hunt for food. Briareus , from the Florida Keys is one species claimed to crawl out of water, over rocks, and up walls. They remain out of the water only for a short period of time since they breathe using gills. What is the largest octopus? The largest octopus is the North Pacific giant octopus ( Octopus dofleini ). It lives in the Northeast and the Northwest Pacific Oceans and weighs about 15kg. Some of the largest ones weigh up to 50kg and measure up to 3-5 meters total length. How do octopuses reproduce? The male has a modified arm called a hectocotylus that he stretches out to the female and inserts into her mantle cavity. The arm transfers spermatophores from a storage sac into her mantle cavity near the oviduct where the eggs are fertilized. Shortly after the eggs hatch, the female dies. How does a giant squid eat? A giant squid has two long tentacles that make up much of the total length of the animal. Each tentacle terminates with a flattened club that has several hundred suckers on one side. The tentacles grab prey and transfer it to the 8 arms where the squid’s muscular, beak-like mouth bites out chunks to swallow. The food then travels down the esophagus, which runs through the squid’s brain. How big can a giant squid grow?
