Our Eyes and Our Vision
Eyesight is one of our most precious possessions, and it lets us enjoy our life to the fullest and appreciate the world around us. We use our eyes every day, but we dont think much about how they work. Written by two experts on the eye, Our Eyes and Our Vision explains the miracle of eyesight. Youll discover what can go wrong with your vision, how to prevent and cure problems, how ancient scholars treated ocular diseases, and what the future has in store for helping to protect and restore vision. Some eyesight problems can be prevented or corrected, but others can only be postponed. Its critical to understand the landscape so that problems can be avoided or addressed as soon as possible. Youll gain deep insights into how we see, and youll also learn how weve gained knowledge about treating eye diseases over the years. If you are interested in general health issues, human anatomy and physiology, biology in general as well as history or just an average reader wanting to learn more about your eyesight, youll be fascinated by Our Eyes and Our Vision.
The Fisherman's Ocean
Tides, currents, fish senses and behavior "Reading Dave Ross's work will give you in-depth knowledge of the ocean, its processes, and marine fish, which can only make you a better saltwater angler."--Joe Healy editor, Saltwater Fly Fishing Here at last, in layman's terms, is a fisherman's guide to the habitat and behavior of saltwater fish. The author, an oceanographer and avid fly fisherman, explains the marine environment and the factors that affect where game fish congregate, how they move with tides and currents, what they see, smell, taste, and hear. The copiously illustrated text covers inshore and offshore habitat and will prove invaluable to anyone who fishes in saltwater, whether in the surf, on the flats, or out at sea. The ocean is vast. It pays to be educated.
Fishes
One fish, two fish, red fish, nearly thirty thousand species of fish -- or fishes, as they are properly called when speaking of multiple species. This is but one of many things the authors of this fascinatingly informative book reveal in answering common and not-so-common questions about this ubiquitous group of animals. Fishes range in size from tiny gobies to the massive Ocean Sunfish, which weighs thousands of pounds. They live in just about every body of water on the planet. Ichthyologists Gene Helfman and Bruce Collette provide accurate, entertaining, and sometimes surprising answers to over 100 questions about these water dwellers, such as "How many kinds of fishes are there?" "Can fishes breathe air?" "How smart are fishes?" and "Do fishes feel pain?" They explain how bony fishes evolved, the relationship between them and sharks, and why there is so much color variation among species. Along the way we also learn about the Devils Hole Pupfish, which has the smallest range of any vertebrate in the world; Lota lota, the only freshwater fish to spawn under ice; the Candiru, a pencil-thin Amazonian catfish that lodges itself in a very personal place of male bathers and must be removed surgically; and many other curiosities. With over 100 photographs -- including two full-color photo galleries -- and the most up-to-date facts on the world's fishes from two premier experts, this fun book is the perfect bait for any curious naturalist, angler, or aquarist.
