At the first underwater museum in the U.S., you’ll find a motley crew of characters. There's an oversized skull, a deer, a pineapple, and a model of undersea explorer Jacques Cousteau's scuba mask.

Seven sculptures in total are coming to the Underwater Museum of Art—UMA for short, pronounced like the actress—which will make its debut off the coast of South Walton, Florida, in late June.

Unlike most museums, visitors don't need to buy tickets. But they will need their own scuba or freediving gear, plus a boat to get to the diving spot, which is located less than a mile off the coast of Grayton Beach.

The sculptures lie at a depth of 60 feet in an area containing an artificial reef, which has grown over the years in an effort to encourage marine life. And statues certainly aren't the only thing to admire underwater—divers have a good chance of spotting turtles, snappers, groupers, and all types of reef fish, according to Andy McAlexander, president of the South Walton Artificial Reef Association (SWARA), which founded the museum in collaboration with the Cultural Arts Alliance of Walton County (CAA).

"It's the Gulf of Mexico. Anything could swim by you," McAlexander says.

McAlexander played a key role in helping UMA get off the ground, and organizers plan to continue expanding their underwater art collection. "We plan on doing it every year, so we'll select between five and seven [artworks] a year from now on," he tells Mental Floss.

When the CAA put out the call for artists who wanted to submit (and submerge) their artwork, they received about 20 entries. Above all else, the sculptures had to be environmentally-friendly and toxin-free, so materials were limited to steel, concrete, and aluminum. That was no problem for artist Rachel Herring, whose father owns a metal fabricating shop. She had taken a few welding lessons from him in the past and put that knowledge to use to construct a large, metal pineapple.

"The pineapple is the symbol of friendship and welcoming, and what better way to welcome wildlife and tourists alike to the Underwater Museum of Art?" Herring writes on her website. "It is intentionally hollow to shelter small fish and wildlife. From above, the leaves splay out to create the view of a sun from above, which is the symbol of life."

Another sculpture mimicking Aqua Lung, a scuba mask invented in the '40s by Cousteau and Émile Gagnan, was created with help from local school students.

The museum may be the first permanent underwater sculpture exhibit in the U.S., but there are other places to see submerged art. In Key Largo, Florida, an underwater sculpture dubbed "Christ of the Abyss" depicts Jesus with outstretched arms.
