pbs.org/wgbh/nova/sharks/island/sansamigos.htmlBig Dos Amigos features a submerged archway that has been likened to an aquatic cathedral. "Light dances off every surface, and the mass of fish and sharks tease and tantalize the eye . . ." wrote one recent visitor. To the south sits Small Dos Amigos, where many species of rays glide through the midwater, and the snappers are so large you barely notice the whitetip reef sharks.
