Ever wondered why there’s a gigantic panorama of fish and other sea creatures wrapped around a four-story building in the median of the Overseas Highway in Key Largo?

Actually, it’s the brainchild of an internationally acclaimed marine life artist who just happens to live in the Upper Keys.

The 7,500-square-foot wraparound mural, located at mile marker 99.2, depicts the living coral reef that parallels the Florida Keys — the only living coral barrier reef in the continental U.S. And thanks to artist and environmentalist Wyland, Keys visitors can preview that reef’s breathtaking ecosystem without getting wet.

For some 30 years, Wyland has used his artistic talent to raise awareness about the need to preserve and protect the oceans and their inhabitants. An avid diver who’s spent hundreds of hours happily submerged in Florida Keys waters, he credits the Keys reef for inspiring much of his work.

“The Florida Keys is one of the best places in the world to dive,” said Wyland. “Every time I dive I learn more, and then I try to incorporate that into my paintings and my sculptures and my murals.”

In fact, just a few miles from the Key Largo mural site lies John Pennekamp Coral Reef State Park, the first underwater preserve in the United States.

Pennekamp is incorporated into the Florida Keys National Marine Sanctuary, which covers about 2,800 square nautical miles of coral reefs, seagrass beds and mangrove swamp on both sides of the Keys island chain — with an indigenous population that includes more than 600 species of fish and 55 varieties of coral. Savvy underwater enthusiasts call the area one of the most fascinating dive sites on the planet.

Wyland’s Key Largo mural, completed in 2007, features manatees, manta rays, corals, sea turtles, fish and bottlenose dolphins.

“This mural is really the gateway to the Florida Keys,” said the artist, who has painted 99 other mammoth marine life murals on buildings around the United States, Australia, France, Japan and other far-flung locations including New Zealand.

Another of his marine life panoramas graces a former warehouse in Key West’s Historic Seaport district, and a third overlooks the Overseas Highway at mile marker 50 in Marathon. Like all of Wyland’s murals, they’re designed to motivate environmental awareness and responsibility — particularly in children.

“Art is something that can touch people’s emotion,” he said. “You can choose not to go into a gallery or a museum, but you can’t ignore a giant mural. If people see this beauty, I know they’ll want to get involved in protecting it.”

Next time you drive into or out of the Keys, immerse yourself in the island chain’s coral reef ecosystem at mile marker 99.2. It’s a great introduction to the underwater world … and you don’t even need to leave your car.
