New insights into the world's most-feared predator.
Sharks are exquisite creatures refined and honed by competitive forces that have lived in balance with ocean prey for millions of years. They live in every ocean habitat on Earth, from shallow tide pools to the deep abyss, and from the open ocean to where rivers meet the sea. In Sharks a top research scientist explores what has made sharks such successful predators, how they differ from other animals in their biological success and what unique advantages evolution has conferred. Sharks is illustrated with uniquely sourced photography demonstrating newly observed behavior, scientific findings and recent developments in our understanding of how they live. Sharks is both a spectacular visual celebration, and a scientific document that explores in detail their unique physiology.
A powerful swimming stroke is delivered from sharks' muscles directly to their tough skin shell forcing their body to "inflate" like a car tire with each flex, then quickly become fluid to glide as the muscles relax. By diving through the various water layers, a shark may locate and follow chemical scent trails that could lead to food concentrations. Thus a shark moving from one temperature layer to the next can expose its sensory equipment to new chemical cues and potentially new food sources. Some deep-sea sharks also lure prey with their light-producing organs.
Salvador Jorgensen has combined the latest discoveries of new species, newly-documented shark behavior, and the best photographs, to give a "state-of-knowledge" picture of sharks. Unique pictures of shark births, recently discovered creatures from the Ocean Census research, and details of sharks' skin, eyes, teeth and heads (including a comparison of nine different hammerhead varieties) make this a book every shark enthusiast will want. It will also debunk many myths about shark behavior, and give readers a true, 21st-century documentation of a very popular wild animal.
Sharks features illustrated profiles of species living in the shallow reefs and also those living in the open ocean along with a unique "cladogram" family tree that opens into a gatefold and profiles every known species.
Fascinating color photos let you see whales in their natural habitat. Learn about their behavior, external anatomy, and physical features. Discussed in the text are the humpback, minke, finback, and the rarely seen right whales, baleen whales that eat by taking in thousands of gallons of water and schools of fish or plankton and filtering the water through the baleen. Discover their behaviors, including breaching, lob tailing, and flipper slapping. This book is a fascinating look at the largest mammals to roam the Earth today.
You have just got to love a colorful, large-format encyclopedia on sharks, and this is one of the best.
--American Reference Books Annual
An up-to-date encyclopedia of the world's most ancient predators.
The Encyclopedia of Sharks is a richly illustrated and fact-filled reference on all the world's species of sharks. The author debunks the fearful myths and fierce legends, providing straightforward facts and the latest research on sharks. More than 200 striking photographs show sharks in their natural habitats. Detailed drawings illustrate the anatomical features unique to sharks, such as their fearsome but short-lived teeth.
The book includes authoritative and updated information on:
- Evolution and design of the shark
- Classifications and orders
- Understanding the shark
- The life of the shark -- how it feeds, breeds and migrates
- Shark "supersense" -- how it survives in the aquatic environment
- The need for protection and conservation -- how sharks are now endangered by over fishing and "finning."
Also included is a 50-page comprehensive, all-color section featuring and explaining the world's most important breeds.
Through its lively text, spectacular photography, and charts, maps and illustrations, The Encyclopedia of Sharks will encourage an understanding of these complex creatures.
From one of the world's most renowned cave divers, a firsthand account of exploring the earth's final frontier: the hidden depths of our oceans and the sunken caves inside our planet
More people have died exploring underwater caves than climbing Mount Everest, and we know more about deep space than we do about the depths of our oceans. From one of the top cave divers working today--and one of the very few women in her field--Into the Planet blends science, adventure, and memoir to bring readers face-to-face with the terror and beauty of earth's remaining unknowns and the extremes of human capability.
Jill Heinerth--the first person in history to dive deep into an Antarctic iceberg and leader of a team that discovered the ancient watery remains of Mayan civilizations--has descended farther into the inner depths of our planet than any other woman. She takes us into the harrowing split-second decisions that determine whether a diver makes it back to safety, the prejudices that prevent women from pursuing careers underwater, and her endeavor to recover a fallen friend's body from the confines of a cave. But there's beauty beyond the danger of diving, and while Heinerth swims beneath our feet in the lifeblood of our planet, she works with biologists discovering new species, physicists tracking climate change, and hydrogeologists examining our finite freshwater reserves.
Written with hair-raising intensity, Into the Planet is the first book to deliver an intimate account of cave diving, transporting readers deep into inner space, where fear must be reconciled and a mission's success balances between knowing one's limits and pushing the envelope of human endurance.
For two months, journalist Heller was aboard the pirate ship the Farley Mowat as it stalked its prey--a Japanese whaling fleet. Now, Heller chronicles this hair-raising journey, whose mission was to stop illegal whaling in the stormy, remote seas off Antarctica. 288.
