National Marine Sanctuaries Gallery

In 1972, exactly 100 years after America's first national park was created, the nation made a similar commitment to preserving its marine treasures by establishing the National Marine Sanctuary Program. These sanctuaries protect more than 18,000 square miles of ocean waters and habitats, an area nearly the size of Vermont and New Hampshire combined. The program is part of the National Oceanic and Atmospheric Administration (NOAA), which works cooperatively with the public to balance enjoyment and use with long-term conservation.

Florida Everglades

The cornerstone of this gallery is an American alligator display, with a focus on the Everglades as a whole. The exhibit shares the success story of the American alligator’s return from near extinction, and raises awareness of other issues facing the Everglades, such as habitat destruction and water quality.

Channel Islands National Marine Sanctuary

The Channel Islands are located 25 miles off the coast of Santa Barbara, California. The waters that swirl around the five islands within the sanctuary combine warm and cool currents to create an exceptional breeding ground for many species of plants and animals.

Cordell Bank National Marine Sanctuary

Cordell Bank is located approximately 52 miles northwest of the Golden Gate Bridge at the edge of the continental shelf. Upwelling of nutrient-rich ocean waters and the bank’s topography create one of the most biologically productive areas on the West Coast. The site is a lush feeding ground for many marine mammals and seabirds.

Fagatele (Fohng-ah-the-leh) Bay National Marine Sanctuary

Fagatele is located on Tutuila, the largest island of American Samoa, and is the only true tropical coral reef in the National Marine Sanctuary Program. This complex ecosystem, with its exceptionally high level of biological productivity, is the smallest and most remote of all sanctuaries.

Florida Keys National Marine Sanctuary

This sanctuary is a complex marine ecosystem surrounding the Florida Keys archipelago, an island chain known worldwide for its extensive offshore coral reef. The waters surrounding most of the 1,700 islands that make up the Florida Keys have been designated a sanctuary since 1990. The Florida Keys marine environment is the foundation for the commercial fishing and tourism-based economies that are vital to southern Florida.

Flower Garden Banks National Marine Sanctuary

Flower Garden is located about 110 miles off the coast of Texas and Louisiana. It harbors the northernmost coral reefs in the continental United States and serves as a regional reservoir of shallow-water Caribbean reef fishes and invertebrates.

Gray’s Reef National Marine Sanctuary

Gray's Reef is located 17 miles off Sapelo Island, Georgia. It is one of the largest near-shore sandstone reefs in the southeastern United States. The rocky platform, some 60–70 feet below the Atlantic Ocean’s surface, is wreathed in a carpet of attached organisms. This flourishing ecosystem provides not only vertical relief, but also a solid base for the abundant invertebrates to attach to and grow upon.

  • Horn Shark

    The horn shark gets its name because it has a short venomous “horn” in front of each of its dorsal fins for protection. The horn shark is typically a brownish color, covered in black spots, and its underbelly has a yellowish tint.

  • Scarlet King Snake

    The scarlet king snake has a tri-color pattern of black, red, and yellow bands that mimic the venomous coral snake. Juveniles usually have the same colors as adults, but often have rings that look more off-white than yellow. As they mature, their rings turn more yellow.
