While the Marine Atlas Volume 1 dealt with anemones (Anthozoa) and crustacea (Decapoda), Volumes 2 and 3 present us with additional invertebrates. However, due to the scope of the subject, only a representative number of invertebrates can be presented, even though these two volumes (2 & 3) together consist of more than 1,300 pages. Approximately 1,000 species of anemones and about 10,000 species of crustacea are known. All of them will never be photographed. The invertebrates in the following two volumes were selected on the basis of their abundance in nature, the depths at which the organisms occur (to 120 feet, corresponding to the diving range of novices), and on the possibility of actually maintaining most of these species in an aquarium. No other book concerning invertebrates has dealt so exhaustively with the husbandry of these beauties, and very few, if any, books provide such expansive information. With over 700 photos (and more than 500 in Volume 3) and explicit textual information, the reader is introduced into a multitude of marine organisms. Soft cover.
