References and Credits Introduction to Cephalopods What group of animals can change color faster than a chameleon plus change texture and body shape, has three hearts pumping blue blood, is jet powered, has members in all oceans of the world - from the tropics to the poles - the intertidal to the abyss, has inspired legends and stories since recorded history, is thought to be the most intelligent of invertebrates and yet is related to animals such as clams and oysters, has members that can squeeze through the tiniest of cracks, is related to garden slugs yet has eyes and other senses that rival our own, and can make their own 'smoke screen' or 'decoys' out of ink? Cephalopods, the group in which scientists classify octopuses, squid, cuttlefish and nautiluses can do all these things and more. Octopuses, squids, cuttlefish and the chambered nautilus belong to class Cephalopoda, which means 'head foot'. Cephalopods are mollusks and therefore are related to bivalves (scallops, oysters, clams), gastropods (snails and slugs), scaphopoda (tusk shells), and polyplacophorans (chitons). Some of these mollusks, like the bivalves, don't even have a head, much less something large enough to be called a brain! Yet cephalopods have well developed senses and large brains and are thought to be the most intelligent of all invertebrates. Most mollusks are protected by a shell and many of them are not very mobile. Although the ancient nautilus has an external shell, the trend in cephalopods is to internalize and reduce the shell. The shell in cuttlefish, when present, is internal. The cuttlebone from cuttlefish is sold in many pet shops to supply calcium to birds. Squid also have a reduced internal shell called a pen. Octopuses lack a shell all together.

For comments, questions and corrections email cephbase@hotmail.com Welcome to CephBase A database-driven web site on all living cephalopods (octopus, squid, cuttlefish and nautilus) March 20, 2003 CephBase is a dynamic relational database-driven web site. The purpose of CephBase is to provide taxonomic data, life history, distribution, images, videos, references and scientific contact information on all living species of cephalopods (octopus, squid, cuttlefish and nautilus) in an easy to access, user-friendly manner. In collaboration with The Sea Around Us Project (Daniel Pauly, Principal Investigator), the species-specific occurrence records already in CephBase and geographical distributions of commercial species in the 1984 FAO Species Catalogue, have been allocated to 18 FAO Statistical Areas, 64 Large Marine Ecosystems and the Exclusive Economic Zones of about 200 maritime countries and territories. See the Biogeography page. Links to country lists are now available on each species page, where applicable. Plots of the occurrence records continue to be available, courtesy of the Kansas Geological Survey Hexacorallia Team, and the distribution range maps can be viewed.

13. IZ Facts - Cephalopods Giant squid longer than 60 feet probably do not exist. How do giant squidmove? Giant squid are jet propelled as are all other cephalopods. http://www.nmnh.si.edu/iz/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?

19. Nautiloid Cephalopods The Nautiloid cephalopods are the group of cephalopods that have a simple suture pattern to the shell. The suture is either gently curved or nearly straight.

Nautiloid Cephalopods The Nautiloid Cephalopods are the group of Cephalopods that have a simple suture pattern to the shell. The suture is either gently curved or nearly straight. Chambered Nautilus The Chambered Nautilus is a living species of the Nautiloid Cephalopods. As you can see in the picture below the shell of the Nautilus is subdivided into various rooms which are connected by a tube called the siphuncle. They are able to use the shell as a buoyance compensation device. They can fill the rooms (camera) with water, air, or possibly sediment to balance their body in the water. This makes the Cephalopod an excellent predator. Ordovician Nautiloid Cephalopod This specimen is from the Ordovician, (Richmond) of southwestern Ohio. The specimen was collected on the banks of the Stillwater River, close to Triangle Park in Dayton, Ohio. This is a popular spot for classes of the Dayton Museum of Natural History, summer program.
