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.

EMAIL US Please wait for the clips to load Octopus Intelligence Reef Cuttlefish Cuttlefish Pulse 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.

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."

Visit Hours Getting to the Zoo Zoo Map ... Humboldt Squid Fact Sheet Related Resources Octopus micropyrsus ) to giant squid ( Architeuthis ), some of which measure over 18 meters long. Although cephalopod species have many differences among them, they all share several common features: Habitat All cephalopods inhabit marine environments. There are no freshwater cephalopod species. Diet Cephalopods are strictly carnivorous. They all possess a hard beak used for defense and tearing prey. Most species hunt for prey, while some are scavengers. Life Span Generally, cephalopods grow quickly and have short life spans. Most live from one to two years, with the exception of the nautilus , which may live more than 15 years. Body Plan Appendages Three Hearts and Blue Blood 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 Cephalopods have the largest brains of any invertebrate, and species of octopus, squid, and cuttlefish are capable of learning and retaining information.

16. Exciting Cephalopods Their chromatophores cannot change color as quickly as other cephalopods , and they do not have ink sacs; instead, they have photophores, http://www.earlham.edu/~merkeka/exciting_cephalopods.htm

Biological Diversity 2001 This image courtesy of CephBase Kingdom: Animalia Phylum: Mollusca Class: Cephalopoda There are three subclasses of cephalopods: Coleoidea, Nautiloidea, and Ammonoidea, which is extinct. Our conservation issues focus on the superorders Decapodiformes (squids and cuttlefishes) and Octopodiformes (octopuses), which are part of the subclass Coleoidea. Subclass: Coleoidea Superorder: Octopodiformes Order: Octopoda photos curtesy of CephBase 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. Order: Vampyromorpha 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!

17. IZ Facts - Cephalopods Giant squid are jet propelled as are all other cephalopods. They pull water into their mantle cavities and then squeeze it out through a funnel at the http://invertebrates.si.edu/cephalopods.htm

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?
