This is an analysis of how conditions in the oceanic environment differ from those in the familiar terrestrial world, describing the techniques and ingenuity required to reveal the populations inhabiting the colossal volume of the deep oceans and how its inhabitants have adapted to survive and flourish within it. Many issues of deep sea marine life are covered including: surface phytoplankton's roles; chemosynthesis at hydrothermal vents and cold seeps; reduction of biomass with depth and energy conservation; mechanoreception; chemoreception; vision; animal life styles, seasonability, sex and size; and the unique variety of life in the deep ocean both on the sea floor at in midwater.
Devoted to the fauna of the deep sea, the intention of this text is to provide an integrated overview of the design, physiology, ecology, and behavior of organisms, small and large. Chapters discuss the challenges and possibilities of studying the deep sea environment, the ways that organisms find energy, the environmental qualities of the benthic environment, patterns of life, biological mechanisms of energy efficiency, sensory apparatuses, the use of camouflage and color, reproductive strategies, and biodiversity. Also included is an appendix that provides listings of the marine phyla. Annotation c. Book News, Inc., Portland, OR (booknews.com)
