A book of this sort has been needed for this age level, and this- while not as popularly slanted as it might have been, should prove a useful, rather sober handbook on plant and animal life along the seashore. Vactioners from twelve up, who fall for the fascination of collecting shells, seawoods and starfish and all their relatives, will find this informative, sound and fairly comprehensive, whatever their happy hunting ground, though the information is more extensive for the eastern seaboard than the Pacific. The text covers in introductory chapters- general discussion of ocean, answering such common questions as why is the sea salty? what are tides? how do tides affect plant and animal life? and so on. The bulk of the text is concerned with types of plant and animal life, from seawoods and sponges, through most of the marine invertebrates, including the familiar lobsters, crabs, bivalves and univalves (shelled animals of the sea), corals, jellyfish, starfish, and dollars and so forth. There is sound scientific data here, and scientific terminology (clarified for the layman by popular ""beach names"") gives this a note of authority. The style is somewhat pedestrian, but this need be no deterrent if what is wanted is information. Forty photographs, numerous drawings and diagrams, will make this a practical guidebook, while instructions on preservation of specimens gives it added value for collectors. Excellent supplementary reading for High School biology.
