The USS Harlequin (AM-365) was an Admirable class minesweeper built for the United States Navy during World War II. She served in the Atlantic, was decommissiond on May 27, 1946 and sold to the Mexican Navy on October 2, 1962, along with 17 other ships. She was commissioned as ARM (Armada de Mexico) DM-20. During 1978, the vessel was converted into an Oceanographic Research Vessel and renamed ARM Oceanografico (H02). In 1993 the ship was reclassified and named the ARM General Pedro Maria Anaya (A08). She was scuttled during May 2000 by then Mexican president Ernesto Zedillo, a diver himself, to serve as an artificial reef and SCUBA dive site. The vessel came to rest upright on a sandy bottom at 80 ft. On October 21-22, 2005 the category 4 Hurricane Wilma broke the shipwreck into two pieces, dragged the bow some distance away, left the stern section on its side, and the aft section upright and intact.
