The lure of the life that inhabits the ocean's reefs and open waters is no secret to scuba enthusiasts and snorkellers who enjoy gazing upon this wonderful world through their dive masks.

This practical and comprehensive guidebook for divers, naturalists and ocean lovers identifies the most commonly encountered animals and other organisms in the tropical marine environment and identifies them in more than 1,000 beautiful colour photographs to provide a window into this magnificent world.
