In recent years, progress in fish biology has advanced at an unprecedented rate and has led to many breakthroughs in the field. This book provides a wealth of information on the strategies that fish adopt with respect to waters with markedly different physical and chemical characteristics. It shows how their physiology, behaviour and lifestyles are adapted to exploit particular niches and gives comprehensive insight into fish life under extreme conditions. The readers are introduced to the ways in which fish exemplify many phenomena of general biological interest - the existence of competitors, chaos, and predator-prey interaction. Fish pathology as well as the components of the immune system are addressed. In this book, original and at times controversial views are presented, areas which have so far received inadequate attention are highlighted and avenues for further research are suggested.

Imagining Rama reveals insights about time, space, consciousness and human freedom, presenting intriguing ways to see the world and a fresh perspective about life. James Harlow Brown takes you on a fascinating and thoughtful tour of some of the unexplored horizons of life in the 21st Century, in a profound yet simple way. He illuminates what lies just out of sight in your everyday life, but within easy reach. As one reader said, "Reading Imagining Rama is a wonderful step away from the everyday grind."

"Ichthyology Handbook" provides comprehensive information on how an ectothermic chordate occupying the base of evolutionary scale, successfully confronts the diverse, everfluxing and stressful milieu. This book introduces the reader to the insights of diverse facets of fish life with emphasis on evolution and phylogeny; skin as an outfit of offence and defence; feeding repertoires; predator-prey relationship; motion, equilibrium and stability; secondary vascular system; respiratory tissues and designs; elimination of nitrogenous waste-products; modes of reproduction, and their functions; sophistication of sensors of natural stimuli; electrogenic and photogenic tissues; migratory behaviour and imprinting; life in unique niches; diseases and control systems and regeneration. The entire text of organ-systems is a testimony to the mastery of this fascinating organism for survival in an aquatic environment.
