Nybakken takes a community ecology approach to his discussions of the marine environment. There are chapters that address communities of the plankton, nekton, deep sea, nearshore subtidal regions, intertidal habitats, estuaries and marshes, the tropics and the poles, and so forth.

The photographs and illustrations are good, the text is well written, and examples are widely known. It may be true that Nybakken tends to pull more heavily on examples from the West Coast of the USA, but there are also ample numbers of examples from other areas of the world that support the text.

Each chapter is supported by a list of references from the professional (primary) scientific literature -- something a serious biology student would appreciate and use.

This is an easy book to teach from and to learn from. The information is excellent, the examples are clear, and the supporting graphics are good.

It is also notable that Nybakken not only discusses the biology of marine organisms, but he addresses the stewardship we have to conserve the planet's vital assemblage of marine resouces and biodiversity.
