Sea stars are well known for their ability to regenerate their arms. What's less apparent is that they accomplish this task without a brain. This book focuses on the sea star's simple nervous system, and it explores some of the interesting things a sea star does without a brain. Readers will be enthralled to learn that a sea star pushes its stomach outside of its body in order to consume its prey. It's a no-brainer that young scientists will be fascinated with this learning experience.
Dinner with a Cannibal by Carole A Travis-Henikoff Pdf
Presenting the history of cannibalism in concert with human evolution, Dinner with a Cannibal takes its readers on an astonishing trip around the world and through history, examining its subject from every angle in order to paint the incredible, multifaceted panoply that is the reality of cannibalism. At the heart of Carole A. Travis-Henikoff’s book is the question of how cannibalism began with the human species and how it has become an unspeakable taboo today. At a time when science is being battered by religions and failing teaching methods, Dinner with a Cannibal presents slices of multiple sciences in a readable, understandable form nested within a wealth of data. With history, paleoanthropology, science, gore, sex, murder, war, culinary tidbits, medical facts, and anthropology filling its pages, Dinner with a Cannibal presents both the light and dark side of the human story; the story of how we came to be all the things we are today.
This ebundle includes: Blindsight, Echopraxia, and The Colonel. From Hugo, Nebula, and John W. Campbell award-nominated author Peter Watts, Firefall is a far-future, science fiction saga of first contact with an alien species at the edge of the solar system–and of the evolution of humanity into a myriad of subspecies. Blindsight: Two months since the stars fell. Now some half-derelict space probe, sparking fitfully past Neptune's orbit, hears a whisper from the edge of the solar system: a faint signal sweeping the cosmos like a lighthouse beam. Whatever's out there isn't talking to us. So who do you send to force introductions with unknown and unknowable alien intellect that doesn't wish to be met? You send a linguist with multiple personalities, her brain surgically partitioned into separate, sentient processing cores. You send a biologist so radically interfaced with machinery that he sees x-rays and tastes ultrasound. You send a pacifist warrior in the faint hope she won't be needed. You send a monster to command them all, an extinct hominid predator once called vampire, recalled from the grave with the voodoo of recombinant genetics and the blood of sociopaths. And you send a synthesist—an informational topologist with half his mind gone—as an interface between here and there. Pray they can be trusted with the fate of a world. They may be more alien than the thing they've been sent to find. Echopraxia: Daniel Bruks is a living fossil: a field biologist in a world where biology has turned computational, a cat's-paw used by terrorists to kill thousands. Taking refuge in the Oregon desert, he's turned his back on a humanity that shatters into strange new subspecies with every heartbeat. But he awakens one night to find himself trapped on a ship bound for the center of the solar system. Their pilgrimage brings Dan Bruks, the fossil man, face-to-face with the biggest evolutionary breakpoint since the origin of thought itself. The Colonel: Colonel Keaton is in trouble. His wife has retreated into a virtual heaven and his son remains missing after joining an extrasolar mission to track down an alien race. He is presently tasked by his superiors with the threat assessment of hived human intelligences, one of which successfully attacks a compound under his watch. Now, one of the strongest hive minds in the world approaches Keaton with an offer that could completely change his world.

When viewed from a quiet beach, the ocean can seem calm, even serene. But hidden beneath the sea's waves are a staggering variety of active creatures, engaged in the never-ending struggles of life--to reproduce, to eat, and to avoid being eaten. Marine scientist Ellen Prager takes us deep into the sea to introduce a cast of fascinating and bizarre creatures. From the tiny arrow worms whose voracious ways may lead to death by overeating, to the lobsters that battle rivals or seduce mates with their urine, Prager reveals the ways they interact as predators, prey, or potential mates. And while these animals make for some jaw-dropping stories--there's far more to Prager's account than entertaining anecdotes: again and again, she illustrates the crucial connections between life in the ocean and humankind, in everything from our food supply to our economy, and in drug discovery, biomedical research, and popular culture.--From publisher description.

A Galaxy of Sea Stars by Jeanne Zulick Ferruolo Pdf
A Bank Street Best Book of 2021 A Galaxy of Sea Stars is Jeanne Zulick Ferruolo’s second middle-grade novel—a heartwarming story about family, loyalty, and the hard choices we face in the name of friendship. Sometimes, the truth isn’t easy to see. Sometimes, you have to look below the surface to find it. Eleven-year-old Izzy feels as though her whole world is shifting, and she doesn’t like it. She wants her dad to act like he did before he was deployed to Afghanistan. She wants her mom to live with them at the marina where they’ve moved instead of spending all her time on Block Island. Most of all, she wants Piper, Zelda, and herself—the Sea Stars—to stay best friends, as they start sixth grade in a new school. Everything changes when Izzy’s father invites his former interpreter’s family, including eleven-year-old Sitara, to move into the marina’s upstairs apartment. Izzy doesn’t know what to make of Sitara—with her hijab and refusal to eat cafeteria food—and her presence disrupts the Sea Stars. But in Sitara Izzy finds someone brave, someone daring, someone who isn’t as afraid as Izzy is to use her voice and speak up for herself. As Izzy and Sitara grow closer, Izzy must make a choice: stay in her comfort zone and risk betraying her new friend, or speak up and lose the Sea Stars forever.
Most of us never think about how we get from one place to another. For most people, putting one foot in front of the other requires no thought at all. Yet the fact that we and other species are able to do so is one of the great triumphs of evolution. To truly understand how life evolved on Earth, it is crucial to understand movement.ÊRestless CreaturesÊmakes the bold new argument that the true story of evolution is the story of locomotion, from the first stirrings of bacteria to the amazing feats of Olympic athletes. By retracing the four-billion-year history of locomotion, evolutionary biologist Matt Wilkinson shows how the physical challenges of moving from place to placeÑwhen coupled with the implacable logic of natural selectionÑoffer a uniquely powerful means of illuminating the living world. Whales and dolphins look like fish because they have been molded by the constraints of underwater locomotion. The unbending physical needs of flight have brought bats, birds, and pterodactyls to strikingly similar anatomies. Movement explains why we have opposable thumbs, why moving can make us feel good, how fish fins became limbs, and even whyÑclassic fiction notwithstandingÑthere are no flying monkeys nor animals with wheels. Even plants arenÕt immune from locomotionÕs long reach: their seeds, pollen, and very form are all determined by their aptitude to disperse. From sprinting cheetah to spinning maple fruit, soaring albatross to burrowing worm, crawling amoeba to running humanÑall are the way they are because of how they move. There is a famous saying: Ònothing in biology makes sense unless in the light of evolution.Ó As Wilkinson makes clear: little makes sense unless in the light of locomotion. A powerful yet accessible work of evolutionary biology,ÊRestless CreaturesÊis the essential guide for understanding how life on Earth was shaped by the simple need to move from point A to point B.
The past one hundred years of ocean science have been distinguished by dramatic milestones, remarkable discoveries, and major revelations. This book is a clear and lively survey of many of these amazing findings. Beginning with a brief review of the elements that define what the ocean is and how it works—from plate tectonics to the thermocline and the life within it—Wolf H. Berger places current understanding in the context of history. Essays treat such topics as beach processes and coral reefs, the great ocean currents off the East and West Coasts, the productivity of the sea, and the geologic revolution that changed all knowledge of the earth in the twentieth century.
Finalist for the National Book Award for Nonfiction * New York Times Bestseller * Starred Booklist and Library Journal Editors’ Spring Pick * A Huffington Post Notable Nonfiction Book of the Year * One of the Best Books of the Month on Goodreads * Library Journal Best Sci-Tech Book of the Year * An American Library Association Notable Book of the Year “Sy Montgomery’s The Soul of an Octopus does for the creature what Helen Macdonald’s H Is for Hawk did for raptors.” —New Statesman, UK “One of the best science books of the year.” —Science Friday, NPR Another New York Times bestseller from the author of The Good Good Pig, this “fascinating…touching…informative…entertaining” (The Daily Beast) book explores the emotional and physical world of the octopus—a surprisingly complex, intelligent, and spirited creature—and the remarkable connections it makes with humans. 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.
