An appealing addition to the ""Ocean Library"" series that describes various means of sea locomotion, considering creatures that paddle, leap, fly, jet, drift, creep, and walk. Vivid color photos focus on features that aid locomotion--from flippers and fins to siphons and suction disks. While much of the information here can be found in other sources, the attractive presentation and helpful appendices make this a useful browsing title. Table of sea facts; glossary; suggestions for further study; list of common and scientific names for the creatures discussed; selected bibliography; extensive index.
