HOME CEPH CARE SCIENCE FOSSILS ... ABOUT US Visit to the National Resource Center for Cephalopods (NRCC) Ceph Articles Two TONMO.com moderators met face to face in the autumn of 2002: Colin Dunlop traveled from Scotland to Texas to help Nancy King set up her saltwater aquarium and to accompany Nancy and her husband Bill to Galveston, where Colin and Nancy visited the NRCC. This is a report of that visit. By Colin Dunlop and Nancy King Galveston Island is most famous for its hurricanes, its architecture and its sandy beaches. But did you know it is also the epicenter for cephalopod study? So we decided to visit this internationally-known cephalopod resource and research center, the NRCC, located on a barrier island about fifty miles from Houston in the city of Galveston. As a branch of the University of Texas Medical Branch (UTMB), secreted away along the side of a pier and barely identified by a small NRCC sticker near the door stands the place where so many cephalopod breakthroughs have been made. It is also the place where many documentaries such as Incredible Suckers have been filmed.

42. Mollusks Lesson Plans And Activities bivalves animals with two shells such as clams, oysters, and scallops. cephalopods - soft bodied animals with no shell such as octopus, squid, and cuttlefish. http://www.geocities.com/Athens/Atrium/5924/mollusks.htm

There are more mollusks on earth than fish, birds, mammals, reptiles or amphibians! Wow! That's a lot! Background: Mollusks are soft bodied animals. They are invertebrates which means that they don't have a backbone. The largest three categories of mollusks are: univalves - animals with one shell such as a conch, oyster drill, and abalone bivalves - animals with two shells such as clams, oysters, and scallops cephalopods - soft bodied animals with no shell such as octopus, squid, and cuttlefish. The word cephalopod means "head foot." Giant squid are the largest cephalopod (octopus, cuttlefish, squid) and the largest mollusk. The largest recorded giant squid was 59 feet long. The average size of the giant squid is 20 to 43 feet long and between 110 and 660 pounds. The octopus and squid are considered to be the most intelligent of all invertebrates. They have well developed eyes and brains. Their eyes are similar to human eyes. Activities: Bring in boxes of shells which students classify into two groups: bivalves and univalves. Try to have an abalone shell because the kids always have a discussion as to how to classify it.

44. AMAZING CUTTLEFISH - Cephalopods Cuttlefish are softbodied marine cephalopods, with a large head ringed by tentacles and an internal cuttlebone. Cuttlefish display http://www.windspeed.net.au/~jenny/cuttlefish/cephalopods.html

Cuttlefish belong to the Class Cephalopoda, which forms part of the Phylum Mollusca. Cephalopods are: soft-bodied marine animals with a large head and a ring of sucker-bearing tentacles have three hearts, a systematic heart that pumps blood throughout the body and two brachial hearts that pump blood to the gills use a form of jet propulsion to move utilize amazing natural camouflage skills to blend in can squirt out sepia ink when threatened are fast moving and relatively intelligent They are the most highly evolved invertebrates and exhibit quite complex behaviour. The Cephalopod group includes the (1) Octopus, (2) Squid, (3) Nautilus and of course, the (4) Cuttlefish. Cephalopods are an ancient group that first evolved sometime during the Late Cambrian. Scientists believe that the ancestor of modern cephalopods was a mollusc that developed an air space within it's shell and worked out a method for regulating the air in it. Predators could be avoided by just floating up off the ocean bottom and the cephalopods could transport themselves over large distances without expended much energy to search of food. Some scientists also believe that the sub-class Coleoidea which contains the octopus, squid and cuttlefish, diverged from the more primative sub-class Nautiloidea (the Nautilus) as far back as in the Ordivician.

CEPHALOPODA, GASTROPODA CEPHALOPODS Phylum Mollusca (Precambrian-Recent) Class Cephalopoda (Cambrian-Recent) Subclass Coleoidea (Devonian-Recent) Subclass Nautiloidea (Cambrian-Recent) Subclass Ammonoidea (Devonian-Cretaceous) Class CEPHALOPODA The cephalopods are a class of mobile mollusks, most of which are nektic or nekto-benthic. Cephalopods have a bilaterally symmetrical body, a prominent head, and a modified foot in the form of tentacles. Although during the Paleozoic and Mesozoic, cephalopods achieved great diversity and abundance in marine habitats, only two genera possessing skeletons are known today. See the example of a Nautilus. Superficially the shell or conch of cephalopods resemble gastropods; however, most cephalopods coil in a plane, whereas gastropods are helicoiled. Furthermore, in cephalopods with an external conch, the coiled shell is chambered. Cephalopod Morphology Some morphologic terms you should become familiar with are given below.

Fish vs. Cephalopods 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.) There are many similarities between cephalopods and fish that suggest that they are a prime example of convergent evolution driven by their competition for the same resources, in the same recent era. This view has been forcefully stated in the review article: "Cephalopods and Fish: the limits of convergence", A. Packard, Biological Reviews 47: 241-307 (1972). This article discusses "the remarkable fact that cephalopods are like fish in almost every feature except their basic anatomical plan." A contrasting view has been presented in: "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."

Illinois State Geological Survey Coiled Cephalopod (Metacoceras) (sef' ah lo pods) Cephalopod fossils have been found in rocks of many ages, and numerous representatives are alive today. Squids, octopuses, cuttlefish, and the pearly nautilus are among the cephalopods living in modern seas. All are members of the large phylum Mullusca. Cephalopods are the most advanced class of the mulluskes. They have a distinct head, a highly developed nervous system, and eyes much like those of humans. The cephalopod's mouth is surrounded by long tentacles commonly armed with suckers. Beneath the tentacles is a tube, the siphon, through which the animal can force a jet of water and thus move about by jet propulsion. Coiled cephalopods live today only in the South Pacific, but in the geologic past they were scattered throughout the world. Modern squids live in shallow coastal waters over much of the globe. Most of the cephalopods we find as fossils had a calcareous outer shell. Some were loosely coiled, some tightly coiled, and others were shaped like a tapered tube.

55. Cephalopods In Cinema 20,000 TENTACLES UNDER THE SEA cephalopods IN CINEMA. By Roland C. Anderson. A very few movies show cephalopods sympathetically. http://www.nhm.ac.uk/hosted_sites/tcp/awful.html

20,000 TENTACLES UNDER THE SEA CEPHALOPODS IN CINEMA By Roland C. Anderson This article originally appeared in Of Sea and Shore, 15(2):78-84, 1992 and is printed here with the permission of the editor. This is an updated version. Octopuses and squids, usually of the giant variety, have long figured prominently in movies. They are usually portrayed as 'monsters of the deep' with insatiable appetites for human flesh, reaching gigantic proportions, able to drag down ships or submarines with ease, and use hardhat or SCUBA divers for appetizers or dessert. They frequently have a propensity for lurking in sunken ships, particularly guarding the treasure chest of gold or pearls we know all sunken ships have on board. Early movies just assumed octopuses and squids were of gigantic proportions, capable of terrorizing whole cities and gulping people like popcorn. More modern movies, hopefully reflecting the sophistication of modern audiences, have to rely on radiation, genetic creation, or pollution to create hybrid monsters of the deep. A very few movies show cephalopods sympathetically. After looking for cephalopods in about 200 movies on marine related subjects, I have found about 60 that have cephalopods in them, from 1916 to 1997. This list is by no means comprehensive, as I have had to rely primarily on films available on video or seen on TV. By perusing comprehensive movie guides, I have discovered another 5 or 10 that are possibilities for having cephalopods in them that I have been unable to obtain or rent.

There are approximately 650 living species, ranging from the tiny paper nautilus to the giant squid. The name "Cephalopoda" literally means "head-foot", as the foot is directly attached to the head. This is one of several characteristics that most members of this class share. The most noticeable characteristic is the tentacles. Ranging in number from 8 to 90 depending on the species, these tentacles form a crown around the head and are specialized for grasping prey. These tentacles are specialized feet, and are sometimes equipped with suckers for extra grip. These suckers may be further equipped with hooks. This class has a very specialized foot known as the siphon, or hyponome, and enables them to locomote. Water is drawn into the mantle cavity and then forcibly expelled through the siphon, creating a jet propulsion that shoots them forward, backward, up, down, side to side, depending on what direction the siphon is pointed. Most cephalopods have a chambered shell, the most notable example being the nautilus with its large, snail-like shell. Other cephalopods, such as squid or cuttlefish, have a smaller, internal shell. Octopods lack shells entirely.

Although the living cephalopods, as a group, are mostly the shell-less octopi and squid, throughout geological history the fossil record has been dominated by species with external or internal shells. Cephalopods are characterized by a well-developed head, generally large brain and eyes, and a series or arms or tentacles. Most cephalopods (except the octopi and squid also have a symmetrical, cone-shaped shell with internal partitions called septae. The shells may be straight or coiled. Even or contorted sutures are usually visible on the outside of the of the shell marking the internal septae. Cephalopods are marine and predaceous. The cephalopods occur in the fossil record from the late Cambrian to the Recent. The cephalopods are divided into six primary orders.
