An engaging and beautifully illustrated introduction to some of the world’s most interesting and charismatic marine creatures Dive deep into the fascinating world of cephalopods—octopuses, squid, cuttlefish, and the mysterious nautilus—to discover the astonishing diversity of this unique group of intelligent invertebrates and their many roles in the marine ecosystem. Organized by marine habitat, this book features an extraordinary range of these clever and colorful creatures from around the world and explores their life cycles, behavior, adaptations, ecology, links to humans, and much more. With stunning photographs and illustrations as well as profiles of selected species, The Lives of Octopuses and Their Relatives is a comprehensive, authoritative, and inviting introduction to the natural history of these charismatic creatures.

Before there were mammals on land, there were dinosaurs. And before there were fish in the sea, there were cephalopods-the ancestors of modern squid and Earth's first truly substantial animals. Cephalopods became the first creatures to rise from the seafloor, essentially inventing the act of swimming. With dozens of tentacles and formidable shells, they presided over an undersea empire for millions of years. But when fish evolved jaws, the ocean's former top predator became its most delicious snack. Cephalopods had to step up their game. Many species streamlined their shells and added defensive spines, but these enhancements only provided a brief advantage. Some cephalopods then abandoned the shell entirely, which opened the gates to a flood of evolutionary innovations: masterful camouflage, fin-supplemented jet propulsion, perhaps even dolphin-like intelligence. Squid Empire is an epic adventure spanning hundreds of millions of years, from the marine life of the primordial ocean to the calamari on tonight's menu. Anyone who enjoys the undersea world-along with all those obsessed with things prehistoric-will be interested in the sometimes enormous, often bizarre creatures that ruled the seas long before the first dinosaurs.

"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.

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.

In pursuit of the wild, solitary, predatory octopus, popular naturalist Sy Montgomery has practiced true immersion journalism. From New England aquarium tanks to the reefs of French Polynesia and the Gulf of Mexico, she has befriended octopuses with strikingly different personalities—gentle Athena, assertive Octavia, curious Kali, and joyful Karma. Each creature shows her cleverness in myriad ways: escaping enclosures like an orangutan; jetting water to bounce balls; and endlessly tricking companions with multiple “sleights of hand” to get food. Scientists have only recently accepted the intelligence of dogs, birds, and chimpanzees but now are watching octopuses solve problems and are trying to decipher the meaning of the animal’s color-changing techniques. With her “joyful passion for these intelligent and fascinating creatures” (Library Journal Editors’ Spring Pick), Montgomery chronicles the growing appreciation of this mollusk as she tells a unique love story. By turns funny, entertaining, touching, and profound, The Soul of an Octopus reveals what octopuses can teach us about the meeting of two very different minds.

Jeanne Villepreux-Power was never expected to be a scientist. Born in 1794 in a French village more than 100 miles from the ocean, she pursued an improbable path that brought her to the island of Sicily. There, she took up natural history and solved the two-thousand-year-old mystery of how of the argonaut octopus gets its shell. In an era when most research focused on dead specimens, Jeanne was determined to experiment on living animals. And to keep sea creatures alive for her studies, she had to invent a contraption to hold them—the aquarium. Her remarkable life story is told by author, marine biologist, and octopus enthusiast Danna Staaf.

“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.
