Fishes:: The Animal Answer Guide Discover 25 Printable paper and disney wallpaper ideas disney. 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.
