    Extractions: date: Calling this a newly discovered large squid just doesn't do it justice. It looks like a manta ray attached to ten twenty-foot lengths of wire, or some '50s monster movie's rendition of a giant space virus. I recommend all the quicktime movies on this page date: A 13-foot-long, 165-pound octopus was caught off New Zealand. Is it the largest ever found or isn't it? "Nothing remotely comparable to the size of the New Zealand specimen has ever been described before," Dr O'Shea said. But The Octopus News Magazine Online ran this comment: The record for the largest octopus ever seen was for a Giant Pacific Octopus that weighed 272 kg (600 pounds!) and was 30 feet from arm tip to arm tip, according to several scientific papers. While there is some concern over how accurately the animal was weighed, it was clearly well over the "new" record described above. - Dr. James B. Wood date: Live giant squid seen for the first time but only juveniles, and they didn't survive in captivity.

    Extractions: Cephalopods have large heads with tentacles ringed around the mouth. Cuttlefish are soft-bodied marine cephalopods with natural camouflage, jet propulsion and sepia ink squirting abilities. 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. They use a form of jet propulsion to move, utilize amazing natural camouflage skills to blend in and can squirt out sepia ink when threatened. All cephalopods have three hearts, a systematic heart that pumps blood throughout the body and two brachial hearts that pump blood to the gills. Cephalopods are fast moving and relatively intelligent. They are the most highly evolved invertebrates and exhibit quite complex behaviour. Other cephalopods include the Octopus, Squid and Nautilus. 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.

    Extractions: No. of Visitors jenny@windspeed.net.au All cuttlefish are "amazing". They are intelligent and exhibit quite complex behaviour. Cuttlefish are soft-bodied marine animals that can change both the colour and texture of their skin rapidly to provide natural camouflage. When threatened, a cuttlefish will squirt sepia ink into the water and hurry away using a form of jet propulsion. Cuttlefish glide through the water by gently rippling their skirt-like fins. They have neutral buoyancy and can vary their depth easily by changing the proportion of liquid to air in their internal skeleton, the cuttlefish bones. Cuttlefish belong to the Class Cephalopoda and like all cephalopods, they have a large head that is ringed by tentacles. Web-site updated by Netweb Design (Sept' 00)

NAUTILOIDS Nautiloids are the first form of cephalopod. They first appear in the Cambrian Period, and are characterized by smooth, usually flat or gently infolded chamber walls. The chambers are filled with gas, which the nautiloid uses to buoy itself in the water. Straight nautiloids are the most primitive, and transitional partly coiled and fully coiled nautiloids are also known. Coiled nautiloids eventually gave rise to the ammonoids - goniatites, ceratites, and ammonites. Nautiloids are the only surviving shelled members of the cephalopods. Nautiloid

    Extractions: Cephalopods The nautiloid cephalopods (feet before head) are an ancient and spectacular success story. Small and rare during the late Cambrian, the nautiloids evolved very quickly along many different lines. At least ten different orders flourished at this time, all but one appearing for the first time during the early or middle part of the Ordovician. This astonishing diversity included straight, curved, loosely coiled, and tightly coiled shelled types, and even one group (the Ascocerids ) that in order to become lighter and more streamlined lost a large part of their shell altogether. These intelligent carnivorous mollusks replaced the Cambrian Anomalocarids as the dominant life form and top predator of the world's ocean. The biggest, such as the endocerids , attained huge size; with shells 3 to 5 meters or more in length they were the largest animal that had ever lived.

    Extractions: This order (photos above and below) includes the common 'octopus,' and the finned octopods found deep in the oceans and sometimes in shallow polar waters. Finned octopods, or Cirrata, have cirri (hair-like structures, probably for feeding) lining each of their arms. The Incirrata have no fins, and their arms are lined exclusively with suckers. This image courtesy of the University of Arizona, Tree of Life One species of Vampyromorpha is known to exist - the vampire squid. These creatures share traits with both octopods and decapods, but have special adaptations for deep-sea life. They are gelatinous and their second pair of arms are special sensory filaments. Their chromatophores cannot change color as quickly as other cephalopods', and they do not have ink sacs; instead, they have photophores, which exude glowing particles!

    Extractions: E.Widder/Harbor Branch Oceanographic Institution * 1999 There has been some debate in the past about whether or not cephalopods actually bioluminesce. Past studies have speculated that observed luminescence is due to reasons ranging from infection due to luminous bacteria to reflection of ambient light by iridophores. However, it has since been reported that at least some octopods possess a circumoral organ which has the ability to luminesce significantly in conditions that eliminate any type of outside luminescence. It should be noted that this organ is only present in the female gender of the species studied ( Eledonella pygmaea and Japetella diaphana) . This fact points to the conclusion that bioluminescence is advantagous in the mating behavior of octopods.

    Extractions: See examples of cephalopod fossils Cephalopods are highly specialized free-swimming marine organisms. The body consists of a single shell with the front end of the foot developing a series of tentacles that surround the head. We will study features and evolution of cephalopods under three subheads representing the three subclasses Nautiloidea, Ammonoidea and Coleoidea. Nautiloids occur in rocks over a wide range of ages from Cambrian to Recent . It is represented by the living genus Nautilus. The animal protect itself inside the shell which has an opening called aperture . The animal lives inside the body cavity and it keeps on adding body cavities by depositing walls known as septa . The cavities thus formed are called camerae . The chambers are filled with gas which provides the necessary buoyancy for the animal to float. The septa are all concave towards the body cavity. The camerae are connected to each other by a tube called siphuncle . The siphuncle is held by a series of septal necks from all the septa. The septal necks point away from the aperture. The septa meets the inner wall of the cephalopod shell to form

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.

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.

    Extractions: Image (C) Kevin Davidson Octopods Squid Cuttlefish Sepiolids Deep-sea Vampire Squid Nautiluses Class Cephalopoda Cephalopods are a small class of mollusks arguably containing the most intelligent of all the invertebrates. 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.
