The reef’s scattered rocky outcroppings and ledges provide homes for an abundance of marine life. Crabs, lobsters, soft corals, sponges, sea stars and other organisms form a dense carpet of living creatures, covering the nooks and crannies of Gray's Reef and giving it the name “live bottom." The reef attracts more than 200 species of fish, including black sea bass, snappers, groupers and mackerels. Loggerhead sea turtles, a threatened species, forage and rest year-round at Gray's Reef, and the reef is within the only known winter calving ground for the highly endangered North Atlantic right whale. Gray's Reef also attracts people: recreational boaters, anglers and divers are among the sanctuary's user groups. The bottom 1/3 of Gray's Reef is a research area where fishing and diving are prohibited. Boats may transit across the research area as long as they don't stop and all fishing gear is stowed and unavailable for use. The research area is used exclusively for controlled scientific studies. The 22-square-mile sanctuary is the only protected natural reef and one of a few natural marine protected areas in the Atlantic Ocean between Cape Hatteras, North Carolina and Cape Canaveral, Florida. However, given the sanctuary's remote location 16 miles east of Sapelo Island, Georgia, most people experience Gray's Reef through pictures or videos. Unlike reefs built by corals, Gray’s Reef comprises scattered limestone rock outcroppings that stand above the sandy surface of the nearly flat continental shelf. http://graysreef.noaa.gov/pgallery/welcome.html

Have you tried color hunting at Gray's Reef?

Gray's Reef National Marine Sanctuary is teeming with marine life of all shapes, sizes, and colors, from loggerhead sea turtles that rest at the reef, to the more than 200 unique species of fishes and sharks, and 900 species of invertebrates. Animals on the reef utilize color in a myriad of ways... Some may use their vivid colors to camouflage with their surroundings, and some may be warning that they are venomous and not safe to eat!

Try your hand at color hunting on the reef! Make sure to always follow best diving and fishing practices when exploring your national marine sanctuaries!

It's a turtle shellebration!!

The Gray's Reef Ocean Discovery Center hosted some special guests last weekend: diamondback terrapin hatchlings! Thank you to the Skidaway Audubon who joined the Gray’s Reef team in shellebrating the Georgia sea (and marsh) turtle hatching season.

And thank YOU for hanging out and meeting some of Georgia’s newest shelled residents, participating in a sea turtle spotting activity around the center, diving with sea turtles in VR, and even making your own hatchlings out of reclaimed egg cartons!

Happy Hatching!

Time for a Creature Feature!

Twinkle twinkle little star... you may run into this little star while diving on Gray's Reef National Marine Sanctuary! The Spiny Sea Star is a common visitor of the reef which typically have five rays extending from a central disc and use their tube feet to move around the seafloor and feed on clams, snails, and mussels.

Next time you're on the reef, be sure to enjoy the sea floor full of stars!

You can learn more about the animals that live in live-bottom habitats, like Gray's Reef National Marine Sanctuary, on our website! https://graysreef.noaa.gov/

Can you spot the camouflaged creatures?

Many animals on the reef use camouflage to blend into their surroundings, helping them hide from predators or ambush their next meal! Fish like flounders and bandtail sea robins are perfectly colored to blend in with the sandy seafloor, while many urchins and crabs decorate themselves with shells (or even other animals!) to avoid detection.

While diving on the reef, keep an eye out for these more cryptic species! Or, visit us at the Ocean Discovery Center for a creature scavenger hunt among our replica reef structures!

Once Upon A Tide Story Time!

Dive into a good book with us! Every Tuesday at 11:00 a.m., join us for Once Upon a Tide story time and craft activity.

Each week we read a new book connected to the underwater worlds of our blue planet, from salt marshes to the deep ocean and everything in between! After each story, stay to make a take-home craft related to the book of the week.

All programming at the Ocean Discovery Center is free and open to the public. All ages are welcome!

Happy !

To celebrate this spectacular day, we wanted to share some of the wildlife in and around Gray's Reef National Marine Sanctuary. While the sanctuary itself is offshore, many boaters travel through the marshes before hitting the open ocean. From the marshes to the open ocean, there is an abundance of wildlife to view.

There are so many ways you can help wildife! Volunteer with Gray's Reef National Marine Sanctuary's Ocean Discovery and inspire others through interpretive tours to learn and protect the wildlife found on live-bottom reef. If you are out on the water and see a stranded or injured marine animal, be sure to report it! Check out the links below for information on volunteering and how to report injured marine animals in your area.
