Flower Garden Banks National Marine Sanctuary, located about 115 miles off the coasts of Texas and Louisiana, harbors the northernmost coral reefs in the continental United States and serves as a regional reservoir of shallow water Caribbean reef fishes and invertebrates. The coral reefs rise to within 55 feet of the surface and form the basis for a complex, yet balanced ecosystem. The Banks themselves are surface expressions of salt domes whose formation began 160 to 170 million years ago in what was a shallow sea, subject to evaporation. Today it has become a premier diving destination and attracts scientists from around the world. This Encyclopedia is meant to provide natural history information, video clips, still images, and additional resources to find more information about the marine life found within the sanctuary. We hope you find this to be a valuable resource.
