The profiles are designed to provide coastal managers, engineers, and biologists with a brief comprehensive sketch of the biological characteristics and environmental requirements of the species and to describe how populations of the species may be expected to react to environmental changes caused by coastal development. Each profile has sections on taxonomy, 1 ife history, ecological role, environmental requirements, and economic importance, if appl icable. A three-ri ng binder is used for this series so that new profiles can be added as they are prepared. This project is jointly planned and financed by the U. S. Army Corps of Engineers and the U.S. Fish and Wildlife Service.
