In this mesmerizing book of photography, acclaimed photographer David Liittschwager reveals the unnerving beauty of three notoriously mysterious sea creatures--the jellyfish, octopus, and seahorse--and how they perceive the world. The jellyfish, the octopus, and the seahorse are among the most wondrous species on Earth--as well as some of the most difficult to document using traditional photography methods. Enter celebrated photographer David Liittschwager, who has spent decades developing specialized portraiture techniques to capture these creatures' pulsating bioluminescence, translucent bodies, and ethereal movements. This luminous collection showcases 200 of Liittschwager's most revealing photographs, paired with penetrating essays that explain how a creature without a brain or without bones perceives the world. Bestselling science writers Elizabeth Kolbert, Jennifer Holland, and Olivia Judson explain the biology and advanced cognitive abilities of these spineless denizens of the deep, exquisitely evoking their unnerving yet undeniable charisma. In these pages, you'll glimpse a seahorse only half an inch tall, a moon jelly spinning off a snowflake-shaped clone, and the blinking comb jelly, which may be the most ancient living animal on Earth. Both enlightening and profound, this enchanting book documents the expanding frontiers of marine science, creating a powerful testament to the value and beauty of these little-seen--and endangered--species.
The visually arresting and often misunderstood octopus has long captured popular imagination. With an alien appearance and an uncanny intellect, this exceptional sea creature has inspired fear in famous lore and legends—from the giant octopus attack in 20,000 Leagues Under the Sea to Ursula the sea witch in The Little Mermaid. Yet its true nature is more wondrous still. After decades of research, the authors reveal a sensitive, curious, and playful animal with remarkable intelligence, an ability to defend itself with camouflage and jet propulsion, an intricate nervous system, and advanced problem-solving abilities. In this beautifully photographed book, three leading marine biologists bring readers face to face with these amazingly complex animals that have fascinated scientists for decades. From the molluscan ancestry of today’s octopus to its ingenious anatomy, amazing mating and predatory behaviors, and other-worldly relatives, the authors take readers through the astounding life cycle, uncovering the details of distinctive octopus personalities. With personal narratives, underwater research, stunning closeup photography, and thoughtful guidance for keeping octopuses in captivity, Octopus is the first comprehensive natural history of this smart denizen of the sea.

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.

"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.
