| anatomy of a squid: Octopus, Squid, and Cuttlefish Roger Hanlon, Mike Vecchione, Louise Allcock, 2018-10-31 Cephalopods are often misunderstood creatures. Three biologists set the record straight.—Science News Largely shell-less relatives of clams and snails, the marine mollusks in the class Cephalopoda—Greek for “head-foot”—are colorful creatures of many-armed dexterity, often inky self-defense, and highly evolved cognition. They are capable of learning, of retaining information—and of rapid decision-making to avoid predators and find prey. They have eyes and senses rivaling those of vertebrates like birds and fishes, they morph texture and body shape, and they change color faster than a chameleon. In short, they captivate us. From the long-armed mimic octopus—able to imitate the appearance of swimming flounders and soles—to the aptly named flamboyant cuttlefish, whose undulating waves of color rival the graphic displays of any LCD screen, there are more than seven hundred species of cephalopod. Featuring a selection of species profiles, Octopus, Squid, and Cuttlefish reveals the evolution, anatomy, life history, behaviors, and relationships of these spellbinding animals. Their existence proves that intelligence can develop in very different ways: not only are cephalopods unusually large-brained invertebrates, they also carry two-thirds of their neurons in their arms. A treasure trove of scientific fact and visual explanation, this worldwide illustrated guide to cephalopods offers a comprehensive review of these fascinating and mysterious underwater invertebrates—from the lone hunting of the octopus, to the social squid, and the prismatic skin signaling of the cuttlefish. |

| anatomy of a squid: Squid as Experimental Animals W.J., Jr. Adelman, J.M. Arnold, D.L. Gilbert, 2013-06-29 The predecessor to this book was A Guide to the Laboratory Use of the Squid Loligo pealei published by the Marine Biological Laboratory, Woods Hole, Massachusetts in 1974. The revision of this long out of date guide, with the approval of the Marine Biological Laboratory, is an attempt to introduce students and researchers to the cephalopods and particularly the squid as an object of biological research. Therefore, we have decided to expand on its original theme, which was to present important practical aspects for using the squid as experimental animals. There are twenty two chapters instead of the original eight. The material in the original eight chapters has been completely revised. Since more than one method can be used for accomplishing a given task, some duplication of methods was considered desirable in the various chapters. Thus, the methodology can be chosen which is best suited for each reader's requirements. Each subject also contains a mini-review which can serve as an introduction to the various topics. Thus, the volume is not just a laboratory manual, but can also be used as an introduction to squid biology. The book is intended for laboratory technicians, advanced undergraduate students, graduate students, researchers, and all others who want to learn the purpose, methods, and techniques of using squid as experimental animals. This is the reason why the name has been changed to its present title. Preceding the chapters is a list of many of the abbreviations, prefixes, and suffixes used in this volume. |

| anatomy of a squid: Handbook of Pathogens and Diseases in Cephalopods Camino Gestal, Santiago Pascual, Ángel Guerra, Graziano Fiorito, Juan M. Vieites, 2019-03-07 The aim of this open access book is to facilitate the identification and description of the different organs as well as pathogens and diseases affecting the most representative species of cephalopods focussed on Sepia officinalis, Loligo vulgaris and Octopus vulgaris. These species are valuable ‘morphotype’ models and belong to the taxonomic groups Sepioidea, Myopsida and Octopoda, which include most of the species with a high market value and aquaculture potential. The study is based on photographs at macroscopic and histological level in order to illustrate the role of the most important pathogens and related diseases from the view of a pathological diagnosis. The reader is able to familiarize with functional anatomy, necropsy and general histology of adults and paralarvae, as well as with the identification of different pathogens and pathologies. This work is thus an invaluable guide for the diagnosis of cephalopod diseases. Besides including pathogens for non-European cephalopod species, it also provides a useful contribution encouraging marine pathologists, parasitologists, veterinarians and those involved in fishery sanitary assessments, aquarium maintenance and aquaculture practices aiming to increase their knowledge about the pathology of cephalopods. |
| anatomy of a squid: Kraken Wendy Williams, 2011-03-01 The enthralling examination of one of the most popular and most intriguing animals in the deep blue sea The ocean is the last remaining source of profound mystery and discovery on Earth with eighty percent of it still largely unexplored; thus, it is of perennial fascination. In Kraken: The Curious, Exciting, and Slightly Disturbing Science of Squid, journalist Wendy Williams introduces one of the ocean’s most charismatic, monstrous, enigmatic, and curious inhabitants: the squid. More than just calamari, squid species are fascinatingly odd creatures, with much to teach us about our own species, not to mention the obsessive interest so many of us can't help but have for the enormous beast that is the giant squid, which is quick to attack sperm whales, and even submarines and boats. Williams also examines other equally enthralling cephalopods, including the octopus and the cuttlefish, and explores their otherworldly abilities, such as camouflage and bioluminescence. Kraken takes the reader on a wild ride through the world of squid science and adventure, along the way answering some riddles about how the human brain works, what intelligence really is, and what monsters lie in the deep. Wendy Williams weaves a rich narrative tapestry around her subject, drawing powerfully on the passions and discoveries of scientists, fisherman, and squid enthusiasts around the world. |

| anatomy of a squid: Cephalopods Peter Boyle, Paul Rodhouse, 2008-04-15 Squid, cuttlefish and octopuses, which form the marine mollusc group the cephalopods, are of great and increasing interest to marine biologists, physiologists, ecologists, environmental biologists and fisheries scientists. Cephalopods: ecology and fisheries is a thorough review of this most important animal group. The first introductory section of the book provides coverage of cephalopod form and function, origin and evolution, Nautilus, and biodiversity and zoogeography. The following section covers life cycles, growth, physiological ecology, reproductive strategies and early life histories. There follows a section on ecology, which provides details of slope and shelf species, oceanic and deep sea species, population ecology, trophic ecology and cephalopods as prey. The final section of the book deals with fisheries and ecological interactions, with chapters on fishing methods and scientific sampling, fisheries resources, fisheries oceanography and assessment and management methods. This scientifically comprehensive and beautifully illustrated book is essential reading for marine biologists, zoologists, ecologists and fisheries managers. All libraries in universities and research establishments where biological sciences and fisheries are studied and taught should have multiple copies of this landmark publication on their shelves. |

| anatomy of a squid: Octopuses, Squid & Cuttlefish Ole G. Mouritsen, Klavs Styrbæk, 2021-05-06 Humans everywhere have always been fascinated by octopuses, squid, and cuttlefish, known biologically as cephalopods. They evolved hundreds of millions of years ago and are related to molluscs such as mussels and snails. They can grow to an enormous size with eyes as big as footballs, but they still live for only a couple of years. They mate once in their lifetime and die shortly after. They have blue blood and three hearts and they can shoot out jet-black ink. They have a brain and have behaviours that could be interpreted as signs of intelligence, even though more than half of their brain is distributed in their arms. They are colour blind, but they can change the colour of their skin in a flash. They are masters of disguise and are able to alter the texture of their skin and the patterns displayed on it at lighting speed. They can also ‘taste’ using the suckers on their arms. They can move extremely fast thanks to a jet-propulsion system built into their body cavity. Although they are soft-bodied and look vulnerable, cephalopods are formidable predators. Octopuses have arms that are so strong that they can exert a force equal to hundreds of times their own body weight. Squid and cuttlefish can shoot out a tentacle to capture prey at the speed of a javelin thrown by an expert athlete. Cephalopods are, however, so much more than just fascinating creatures with strange physical characteristics. They are a nutritious, delicious protein source that has found a place for thousands of years in many food cultures around the world. As squid, cuttlefish, and octopuses are native to virtually all parts of the ocean, they are an excellent and available alternative to meat from terrestrial animals. This book is written to promote the overall place of cephalopods in home kitchens and to inspire the uninitiated to add them to their diet. It describes the many facets of their anatomy that play a central role in their potential use as healthy, diverse, and interesting food sources, with a particular emphasis on their taste and texture. By way of an assortment of recipes, the authors hope to dispel the myth that it is difficult to prepare delicious dishes using squid, cuttlefish, and octopuses. In addition, there are contributions to the on-going discussions about how marine resources can be exploited more responsibly in a sustainable manner. Ole G. Mouritsen is a professor of gastrophysics and culinary food innovation at the University of Copenhagen,president of the Danish Gastronomical Academy, and director of the Danish national research and communication centre Taste for Life.

| anatomy of a squid: Monarchs of the Sea Danna Staaf, 2020-09-15 Before mammals, there were dinosaurs. And before dinosaurs, there were cephalopods. Publisher’s Note: Monarchs of the Sea was previously published in hardcover as Squid Empire. Cephalopods, Earth’s first truly substantial animals, are still among us: Their fascinating family tree features squid, octopuses, nautiluses, and more. The inventors of swimming, cephs presided over the sea for millions of years. But when fish evolved jaws, cephs had to step up their game (or end up on the menu). Some evolved defensive spines. Others abandoned their shells entirely, opening the floodgates for a tidal wave of innovation: masterful camouflage, fin-supplemented jet propulsion, and intelligence we’ve yet to fully measure. In Monarchs of the Sea, marine biologist Danna Staaf unspools how these otherworldly creatures once ruled the deep—and why they still captivate us today. |

It also includes the main conclusions which have been drawn from the research and the future challenges in this field. This makes this book not only an ideal introduction to cephalopod culture, but also a valuable resource for those already involved in this topic. |
| anatomy of a squid: Vision in Cephalopods Frederike Diana Hanke, Daniel Colaco Osorio, 2018-03-13 Cephalopods usually have large and mobile eyes with which they constantly scan their environment. The eyes of cephalopods are single-chamber eyes which show resemblance to vertebrate eyes. However there are marked differences such as the cephalopod eye having an everted retina instead of an inverted retina found in vertebrates. Their visual system allows the cephalopods, depending on species, to discriminate objects on the basis of their shapes or sizes, images from mirror images or to learn from the observation of others. The cephalopod visual system is also polarization sensitive and controls camouflage, an extraordinary ability almost exclusive to all cephalopods; they are capable of rapidly adapting their body coloration as well as altering their body shape to any background, in almost any condition and even during self-motion. Visual scene analysis ultimately leads to motor outputs that cause an appropriate change in skin coloration or texture by acting directly on chromatophores or papillae in the skin. Mirroring these numerous functions of the visual system, large parts of the cephalopod brain are devoted to the processing of visual information. This research topic focuses on current advances in the knowledge of cephalopod vision. It is designed to facilitate merging questions, approaches and data available through the work of different researchers working on different aspects of cephalopod vision. Thus the research topic creates mutual awareness, and facilitates the growth of a field of research with a long tradition - cephalopod vision, visual perception and cognition as well as the mechanisms of camouflage. This research topic emerged from a workshop on “Vision in cephalopods” as part of the COST Action FA1301. |
