Unusual and often repugnant features of wild animals are highlighted in this collection filled with their bizarre characteristics. Many of the photographs feature huge open mouths and large sharp teeth. Land animals, sea creatures, birds, and insects are shown in their natural habitatssometimes in the process of eating other beings, both living and dead. Prizes are given for the ugliest animals, with the naked mole-rat coming in first and the proboscis monkey rated as fifth. Animal intelligence, their ways of communicating, and some strange interactions with people are also illustrated. "Twist it!" sections with lists of far-fetched facts require the reader to the turn the book sideways or upside down. Numerous photographs with informative captions contribute to the overall sense of awe. The pages are filled with so many amazing facts that few people will choose to peruse all of them in one sitting. Fortunately, a table of contents and an index will enable readers to go directly to topics of interest. "Ripley's Believe It or Not" series. Reviewer: Phyllis Kennemer, Ph.D.
