Product Description Discusses the characteristics and habits, the family life and intelligence of dolphins and porpoises. From School Library Journal Grade 46 Another science book from Patent that is clearly written and factual. The beautiful color photograph on the cover is inviting, and the blackandwhite photographs on almost every page illustrate the text perfectly. After establishing dolphins and porpoises as underwater mammals, their individual differences are describeddolphins have beaks and coneshaped teeth; porpoises do not have beaks, and their teeth are shaped like little shovels. Yet she admits that it's a confusing difference even to scientists, and that the terms are often used interchangeably. Current scientific discoveries about dolphins are included, e.g., dolphins' sense of taste is now known to detect sweet, sour, bitter, and salty. Patent's writing is lucid, with no wasted words, and the organization of information flows naturally. An essential addition to science collections for younger readers. Frances E. Millhouser, Prince William Library System, Va.Copyright 1989 Reed Business Information, Inc.
