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.

"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.

An introduction to these bizarre and beautiful creatures of the sea, filled with color photos and illustrations: “Fascinating.”—Boing Boing Jellyfish are the oldest multi-organed life form on the planet, having inhabited the ocean for more than five hundred million years. With their undulating umbrella-shaped bells and sprawling tentacles, they are compelling and gorgeous, strange and dangerous. In many places they’re also vastly increasing in number, and these population blooms may be an ominous indicator of the rising temperatures and toxicity of the oceans. Jellyfish presents these aquarium favorites in all their glory. Fifty unique species, from the purple people eater to black sea nettles, are presented in stunning photos along with the most current scientific information on their anatomy, history, distribution, position in the water, and environmental status. Foremost jellyfish expert Lisa-ann Gershwin provides an insightful look at the natural history and biology of each of these spellbinding creatures, plus a timely take on their place in the rapidly changing and deteriorating condition of the oceans. Learn about immortal jellyfish who live and die and live again—as well as those who camouflage themselves amid sea grasses and shells, hiding in plain sight. Discover the jellyfish that’s the world’s most venomous animal, and the jellyfish that helped scientists win the Nobel Prize. They’re all here and more in this delightful volume. “A thorough coverage of jellyfish history, biology and ecology. Gershwin, a marine biologist who has discovered over 200 new species of jellyfish, does an excellent job of combining a compelling narrative of 50 different jellyfish with luscious, I-can’t-believe-they’re-real photos.”—Boing Boing

“A pleasant, chatty book on a fascinating subject.” — Kirkus Reviews Octopuses have been captivating humans for as long as we have been catching them. Yet for all of our ancient fascination and modern research, we still have not been able to get a firm grasp on these enigmatic creatures. Katherine Harmon Courage dives into the mystifying underwater world of the octopus and reports on her research around the world. She reveals, for instance, that the oldest known octopus lived before the first dinosaurs; that two thirds of an octopus’s brain capacity is spread throughout its arms, meaning each literally has a mind of its own; and that it can change colors within milliseconds to camouflage itself, yet appears to be colorblind.

"Craig Foster and Ross Frylinck regularly dive together in the awe-inspiring kelp forests off South Africa, without wetsuits or oxygen tanks. Craig had dived this way for years, including alongside the octopus that inspired My Octopus Teacher. In Ross, he found a kindred spirit, someone who also embraced the ancient methods of acclimating his body to frigid waters, but whose eyes had not yet adjusted to the transcendent wonder Craig saw each time they dove. In the heart-wrenching stories that make up this unforgettable book, we swim alongside Ross as he grows from skeptic to student of the underwater wild. And in the revelatory marine science behind the stunning photos, we learn how to track sea hares, cuttlefish, and limpets, and we witness strange new behaviors never before documented in marine biology. We realize that a whole world of wonder, and an innate wildness within us all, emerge anew when we simply observe. "--publisher's website.
