The comparative physiology of seemingly disparate organisms often serves as a surprising pathway to biological enlightenment. How appropriate, then, that Robert Elsner sheds new light on the remarkable physiology of diving seals through comparison with members of our own species on quests toward enlightenment: meditating yogis.

As Elsner reveals, survival in extreme conditions such as those faced by seals is often not about running for cover or coming up for air, but rather about working within the confines of an environment and suppressing normal bodily function. Animals in this withdrawn state display reduced resting metabolic rates and are temporarily less dependent upon customary levels of oxygen. For diving seals—creatures especially well-adapted to prolonged submergence in the ocean’s cold depths—such periods of rest lengthen dive endurance. But while human divers share modest, brief adjustments of suppressed metabolism with diving seals, it is the practiced response achieved during deep meditation that is characterized by metabolic rates well below normal levels, sometimes even approaching those of non-exercising diving seals. And the comparison does not end here: hibernating animals, infants during birth, near-drowning victims, and clams at low tide all also display similarly reduced metabolisms.

By investigating these states—and the regulatory functions that help maintain them—across a range of species, Elsner offers suggestive insight into the linked biology of survival and well-being.

Bat biologist Barbara A. Schmidt-French and writer Carol A. Butler offer a compendium of insightful facts about bats in this accessible and expertly written question-and-answer volume. Numbering more than one thousand species in our world today, bats in the wild are generally unthreatening. Like most other mammals, bats are curious, affectionate, and even playful with one another.

Highly beneficial animals, bats are critical to global ecological, economic, and public health. Do Bats Drink Blood? illuminates the role bats play in the ecosystem, their complex social behavior, and how they glide through the night sky using their acute hearing: echolocation skills that have helped in the development of navigational aids for the blind. Personal in voice with the perspective of a skilled bat researcher, this book explores wide-ranging topics as well as common questions people have about bats, providing a trove of fascinating facts.

Featuring rare color and black-and-white photographs, including some by renowned biologist, photographer, and author Merlin Tuttle, Do Bats Drink Blood? provides a comprehensive resource for general readers, students, teachers, zoo and museum enthusiasts, farmers and orchardists, or anyone who may encounter or be fascinated by these extraordinary animals.

Who hasn’t fantasized about the unique thrill of working among charismatic and clever dolphins in the wild? Now we no longer have to rely solely on our imaginations . With Dolphin Confidential, Maddalena Bearzi invites all of us shore-bound dreamers to join her and travel alongside the dolphins. In this fascinating account, she takes us inside the world of a marine scientist and offers a firsthand understanding of marine mammal behavior, as well as the frustrations, delights, and creativity that make up dolphin research. 

In this intimate narrative, Bearzi recounts her experiences at sea, tracing her own evolution as a woman and a scientist from her earliest travails to her transformation into an advocate for conservation and dolphin protection. These compelling, in-depth descriptions of her fieldwork also present a captivating look into dolphin social behavior and intelligence. The central part of the book is devoted to the metropolitan bottlenose dolphins of California, as Bearzi draws on her extensive experience to offer insights into the daily lives of these creatures—as well as the difficulties involved in collecting the data that transforms hunches into hypotheses and eventually scientific facts. The book closes by addressing the critical environmental and conservation problems facing these magnificent, socially complex, highly intelligent, and emotional beings.  

An honest, down-to-earth analysis of what it means to be a marine biologist in the field today, Dolphin Confidential offers an entertaining, refreshingly candid, and always informative description of life among the dolphins.
