Introduction Cephalopods (squid, cuttlefish, and octopus) were dominant pelagic predators in marine environments prior to the evolution of teleost fishes. They are still significant members of marine communities in coastal and oceanic waters, although the biology, ecology, and life histories of many speices are poorly described. Chesapeake Bay is home to a small, short-lived cephalopod, the brief squid Lollinguncula brevis Biology of the brief squid, Lolliguncula brevis The distribution, swimming physiology, and swimming mechanics of the brief squid, Lolliguncula brevis , were examined by Ian Bartol as part of his dissertation work. Field collections from local waters coupled with extensive laboratory experiments provided data which shed light on both the ecology and evolution of swimming behavior in this species.

Cephalopods like the Late Cretaceous Scaphites In primitive cephalopods like the pearly nautilus, this shell is external and superficially like that of a gastropod snail. Such a shell serves two functions: defence and buoyancy. More advanced cephalopods have internal shells. The cuttlefish is a cephalopod with an internal shell. While still providing buoyancy, it is no longer protective. These more active cephalopods rely on camouflage or speed to evade predators. The most advanced cephalopods, such as the squids and octopuses do not have chambered shells at all. In squid the shell is a simple, often feather-like, strut while in the octopus it is reduced to small plates around the brain. When swimming, these cephalopods do not rely on buoyancy from the shell. ammonites , below). Some cephalopods had counterweights to maintain a correct orientation. In the nautiloids these weights took the form of solid, calcareous deposits within some of the chambers, usually the ones near the apical end. Among the coleoids, the belemnites had solid counterweights as well, but they surrounded the outside of the shell (but underneath the skin). These counterweights, or guards, are common fossils (see section on

Cephalopods - A World Guide
cephalopods a world guide. Mark Norman, Ikan Underwasserarchiv (Germany),hard cover, 320 pages. Mark Norman is no stranger to cephalopods.
http://www.capricornica.com/book_reviews/cephalopods.htm

Extractions: Mark Norman, Ikan Underwasserarchiv (Germany), hard cover, 320 pages Reviewer: Patty Jansen Review published in: Australasian Shell News No. 110 (June 2001) Another underwater guide published by Helmut Debelius, this is a colourful guide to the worlds octopuses and related animals. The book is presented in the usual colourful, rather screaming and somewhat cluttered style used by Helmut. Leaving the layout aside, this is really a most wonderful book. Almost all animals are photographed in the wild by an impressive gathering of the worlds best underwater photographers. A large part of the book is an identification guide, but what makes Helmuts books so interesting are the case studies, stories of animal behaviour or strange underwater encounters. Mark Norman is no stranger to cephalopods. Just last year he had another book published, Guide to Squid, Octopuses and Cuttlefish of Australia (co-author Mandy Reid, CSIRO Publishing). After a short introduction each order of cephalopods is introduced separately, after which a number of species are described. The descriptions contain information about identification features, distribution, habitat and behaviour. The book contains an index and a list of references. But it is not a scientific guide and really the main strength of the book are the photographs. There are too many great pictures to mention, covering shallow and deep water cephalopods (one photographed at 2400 metres), cephalopod larvae and eggs, cephalopod breeding and many shots of cephalopods in action.
Cephalopods, April 2001
cephalopods Analysis April 2001. PRODUCTION. In 1999, exports of fresh and frozencephalopods have increased by 21% to almost 1.4 miilion MT (US$ 2.4 million).
http://www.globefish.org/publications/commodityupdate/200104/200104.htm

Extractions: Total cephalopod production increased by 28% in 1999 over 1998, a very poor year, to almost 3.4 million MT as a result of increasing output of all main producing countries. The Republic of Koreas production increased by a strong 90% between 1998 and 1999 reaching 590 000 MT and thus keeping this country in the top position among cephalopod producers. Japan is the second main producer with 560 000 MT in 1999, up 25% from 1998 but still below the ten year average (620 000 MT). Thirty-four percent of the total cephalopod catch is taken in the SW Atlantic (1.1 million MT), 29% in the NW Pacific (980 000 MT) and almost 10% in the WC Pacifc (330 000 MT). These shares have increased by 58%, 7% and 9% respectively since 1998. Global octopus production reached its peak in 1999 with 354 000 MT, up 17% from 1998 and 20% more than in 1990. This increase was the result of a doubling in Moroccan (the worlds top octopus producer) output in 1999 to 84 600 MT. Japan holds a 16% share of the worlds octopus catch (1999).Japanese octopus production was 57 300 MT in 1999, slightly less (-7%) than the previous year. Japans production has remained fairly stable over the period. Senegal and Spain are other important octopus catching countries with 37 300 MT and 31 800 MT respectively in 1999. Senegal had a record catch in 1999. The bulk (almost half) of the octopus caught in the world originates from the EC Atlantic , that is 173 000 MT in 1999, 65% more compared to 1998. Nineteen-ninety-nines production is also the highest during the period. The second most important octopus fishing ground is the NW Pacific with an output of 77 000 MT in 1999, 22% of the total octopus production despite the 13% drop since 1998.

Extractions: Only about half a dozen cephalopod species have external shells, and these are members of the nautilus family. They are really natures submarines. They have chambers inside that they can control buoyancy with. They fill these chambers like a submarine does to go up or down in the water column of the ocean. Squids and Octopuses are also in this class of mollusks. Nautilus pampilius Chambered Nautiluses are carnivores, which means they catch other live prey for food. Chambers Also in this class of shells you will find the common spirula shell. It is a shell that is found contained within the body of a squid like animal. The Brown Paper Nautilus to the left are very fragile, and actually used by a female squid-like animal, as an egg case.

Extractions: Photo: Courtesy of Erling Svensen General: Among the cephalopods there are the largest invertebrates on earth. Their nervous system is developed to a much higher degree than that of other molluscs. The complex behaviour of cephalopods makes them comparable to the vertebrates rather than to other invertebrates. Schematic body plan of a cuttlefish ( Sepia The construction of their body shows that cephalopods are molluscs. They have no trace of a skeleton, neither internal nor external. Like that of other molluscs, cephalopods' bodies are divided in head, visceral sac and foot, the mantle (pallium) as a protective coat of the visceral sac. The more modern cephalopods of the subclass called Coleoidea do not have an external shell like the other molluscs. Only members of the most ancient cephalopod groups, the subclass Nautiloidea with it's only recent genus Nautilus , still swim the ocean with a shell ressembling that of a snail. The rest of the cephalopods have an inner shell. That of the cuttlefish for instance is called cuttlebone, though it is neither bone nor skeleton, but a shell rest. Cuttlebones are known to the bird keeper to provide the bird with something to sharpen it's beak. Mostly the spawn packets of squid and their inner shells are the only parts of them that can be found by somebody walking on the beach. Among some squid (
