Anyone left dying of curiosity after reading Moby Dick will surely find surcease here. There seems no end to the material on whales (and porpoises too) collected in this book. (e.g., Cleveland Amory in the June 12, 1965 TV Guide nominated a whale as number one actor....). There is serious information as well, paragraphs of it quoted directly. There appears to be a greater amount of detail than is usually found in books for adolescent readers (e.g., the chapter on the ""Private Life"" of the quickly copulating whale). Whales are one of the sea's most fascinating beasts and both adults and juvenile titles on them find a ready readership.
