Nurse sharks sleep under it, angelfish and sergeant majors work the stools. Shallow enough that you can shoot the whole thing on one breath, and the single most shareable image in Miami's water. Sunk on 5 May 2000 in a José Cuervo-sponsored stunt inevitably nicknamed 'Sinko de Mayo', intended as the first station of a planned South Beach Underwater Trail that was never completed.
