The deepest and largest known springs in the world are found in Florida. This book is a guided tour of these beautiful environments, offering many rare underwater photographs. Beginning with a history of the formation of Florida's springs eons ago and ending with a strong caution on cave diving safety, the reader journeys through these crystal realms, the emphasis always on the natural inhabitants. With many striking photos of these creatures in their natural habitat, this book also serves as a field guide for identification. The photographs represent hundreds of hours of underwater exploration. An appendix offers detailed information on all inhabitants presented. There is a chapter on the saltwater visitors to springs near the sea and a chapter on Florida's most famous—and most endangered—marine mammal, the manatee.

Residents and visitors alike will appreciate the detailed descriptions and maps of Florida's major spring parks and the opportunities for learning about and enjoying their natural wonders through swimming, diving, canoeing, tubing, and other activities. Included are well-known parts such as Silver Springs, Weeki Wachee, Wakulla Springs, Ichetucknee Springs, as well as many lesser-known but equally beautiful spring parks.
