Nautilida The Cephalopods ("head-foot") are the mollusc class Cephalopoda characterized by bilateral body symmetry, a prominent head, and a modification of the mollusc foot into the form of arms or tentacles. Teuthology is the study of cephalopods, and teuthologists are the scientists who study them. The class contains two extant subclasses . In the Coleoidea , the mollusc shell has been internalized or is absent; this subclass includes the octopuses squids , and cuttlefish . In the Nautiloidea the shell remains; this subclass includes the nautilus . There are around 786 distinct living species of Cephalopods. Two important extinct subclasses are Ammonoidea, the ammonites and Belemnoidea , the belemnites. Cephalopods are found in all the oceans of the world and at all depths. They are regarded as the most intelligent of the invertebrates and have well developed senses and large brains . They have special skin cells called chromatophores that change color and are used for communication and camouflage . The nervous system of cephalopods is the most complex of the invertebrates.

The Cephalopod Page (TCP) was created and is maintained by Dr. James B. Wood and is hosted by Dalhousie University and the University of Texas Medical Branch. How can you tell octopus and squid apart? Octopuses, squid and cuttlefish all have 8 arms. In addition, cuttlefish and squid have 2 tentacles. Tentacles are longer then arms and they usually only have suckers at their tips. The public often interchanges the two terms, as they are not aware that they have different meanings. The presence/absence of tentacles is one way to distinguish an octopus from a squid. In addition, cuttlefish have a shell (the cuttlebone) on their back. Are cephalopods dangerous? Much of the "dangerous" image of cephalopods is Hollywood fantasy where you can have tales of cephalopods attacking ships and devouring sailors. 20,000 Leagues Under the Sea and Toilers of the Sea by Victor Hugo are good examples. Since cephalopods can be large, strong, and intelligent and because most people don't know much about them, they make great monsters of the deep. Yes, people have died from octopuses. However, the 'killer octopuses' are very small (smaller than your hand) and rather beautiful. These octopuses, called blue ringed octopuses, are only found in Australia. To get bit, you have to pick one up, or pick up its home (it lives in empty shells). There are giant octopuses (O. dofleini) - they live in the Northeast and Northwest Pacific. An average giant pacific octopus weights around 15 kg or so and is regularly encountered by divers off the West coast of North America. They can weigh up to 50 kg.

See the world (and its fossils) with UCMP's field notes. HOME SEARCH GLOSSARY ... Mollusca The Cephalopoda Squids, octopuses, nautilus, and ammonites FUN FACT: From the dark abyss to shallow tide pools, research has recently revealed some of the mysterious behaviors of two famed cephalopods, the Giant Squid and the deadly Blue-ringed octopus (click image below for an enlargement). Cephalopods are the most intelligent, most mobile, and the largest of all molluscs. Squid, octopuses, cuttlefish, the chambered nautilus, and their relatives display remarkable diversity in size and lifestyle with adaptations for predation, locomotion, disguise, and communication. These "brainy" invertebrates have evolved suckered tentacles, camera-like eyes, color-changing skin, and complex learning behavior. Their lengthy evolutionary history spans an impressive 500 million years and the abundant fossils they've left behind (mostly shelled nautiloids and ammonoids) record repeated speciation and extinction events. From myths about their enigmatic fossilized remains to fantastic accounts of tentacled sea monsters, cephalopods also figure prominently in the literature and folklore of human societies around the world. Today, biologists and paleontologists continue to captivate the human mind and imagination with details of these molluscs' behavior, natural history, and evolution. Fossil record There are about 17,000 named species of fossil cephalopods, compared to the 800 identified living species of cephalopods. Clearly the lineages of extinct taxa were prolific and diverse. So diverse in fact, that paleontologists have identified three distinct fossil clades that are entirely extinct: Endoceratoidea, Actinoceratoidea, and Bactritoidea (cladogram A, at right). All members of these clades were squid-like, but had straight external shells called orthocones. They flourished in Paleozoic oceans between the Ordovician (488 mya) and Triassic periods (200 mya) with shells that, in some species, reached nearly 10 meters in length.

] Subscribe To This Site The Rise And Fall of The Ammonites Ammonites have intrigued mankind for thousands of years. This fossil has created enough interest to inspire dozens of stories, legends and myths The name comes from its appearance: it resembles a ram’s horn. In Egyptian mythology, the God Ammon looked like a man with horns like a ram. The ancient fossil was considered Ammon’s stone, thus inheriting the name, ammonite. Ammonites first appeared in the lower Devonian Period . It is thought by some that they evolved from the older nautiloids. Septa The septa are the walls that devide the chambers within the shell. Nautiloids had simple septa with a single arc. The ammonites developed septa that had intricate folds called lobes and saddles . They also developed delicate lacey patterns on the outer shell. There are three basic patterns for ammonite septa. irregular zigzags-this is called goniatite regular wavy-called ceratite intricate feathery or fern like patterns- ammonite The pattern of the septa can be reflected on the outside of the shell. These are called sutures These patterns along with the shape of the shell and the structure of the septa are how this cephalopod is classified.
