Costumed musicians made a splash off the Florida Keys with a wet and wild underwater concert on Saturday.
More than 500 divers and snorkelers turned the sea floor into a dance floor for the annual Lower Keys Underwater Music Festival to see acts like "Eel-vis Presley" and "Bob Marlin" near a coral-barrier reef about six miles from Big Pine Key, event organizers said.
Although mermaids and Elvis impersonators toted instruments like a "clambourine," and fish-shaped horns and guitars, the music was actually broadcast by speakers hooked to the undersides of boats.
The set list included aquatic hits like the Beatles' "Yellow Submarine," and "Fire" by Jimmy Buffet.
It was the 27th year for the show that aims to raise awareness about the fragile underwater ecosystem.
"We have a lot of fun, we dress up in costumes, but there's a serious side," said festival director Bill Becker in a statement. "Coral reef conservation is the message."
