Beyond the Human Realm

Beyond the Human Realm

Gene Helfman

Luminare Press
2021
pokkari
Time is running out for the iconic killer whales of the Pacific coast. Orca families have been decimated by humanity's greed and folly, their food supply wiped out, their infants dying from starvation and tainted mother's milk. Captive male orca Makai is destined for freedom, but a human-caused tragedy upends his world. Plotting revenge, acceptance into orca society, and reversal of his adopted family's decline, his success hinges on fellow orcas, whale researchers, and a runaway teenager with Orca Clan roots. But Makai's radical plan must first overcome millennia of orca cultural tradition. Profits from the sale of Beyond the Human Realm will be donated to orca conservation efforts.
Sharks

Sharks

Gene Helfman; George H. Burgess

Johns Hopkins University Press
2014
pokkari
Answering every conceivable question about sharks, authors Gene Helfman and George H. Burgess describe the fascinating biology, behavior, diversity (there are more than 1,000 species worldwide), and cultural importance of sharks, their close relationship to skates and rays, and their critical role in healthy ecosystems. Helfman and Burgess take readers on a round-the-world tour of shark habitats, which include oceans as well as lakes and even rivers (as far up the Mississippi as St. Louis). They describe huge, ferocious predators like (Great) White and Tiger sharks and species such as Basking and Whale sharks that feed on microscopic prey yet can grow to lengths of more than 40 feet. The mysterious and powerful Greenland shark, the authors explain, reaches a weight of 2,200 pounds on a diet of seal flesh. Small (less than 2-foot long) Cookiecutter sharks attack other sharks and even take a chunk out of the occasional swimmer. Despite our natural fascination with sharks, we have become their worst enemy. Many shark species are in serious decline and a number are threatened with extinction as a result of overfishing and persecution. Sharks: The Animal Answer Guide presents a perfect mix of current science, history, anthropology, intriguing facts, and gripping photographs. Whether your fascination with sharks stems from fear or curiosity, your knowledge of these animals will improve immensely when you consult this book.

Fishes

Fishes

Gene Helfman; Bruce Collette

Johns Hopkins University Press
2011
pokkari
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 on male bathers and must be removed surgically; and many other curiosities. With more than 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.
