Dark Spots Disease (in depth)

  • Relevant in the Florida Keys and wider Caribbean
  • Affected areas are dark purple, gray or brown
  • circular or irregular in shape scattered on surface of a colony or at colony's margin
  • discolored area increases in size and radiates outward as affected area dies
  • Darkened polyps are often depressed and appear smaller in size
  • Popular on S. siderea (massive starlet coral), blushing star coral, and M. annularis


Black Band Disease

  • Characterized by blackish concentric/crescent-shaped band (given by photosynthetic pigment of the dominant cyanobacteria)
  • Consumes live coral tissue as it passes over colony surface
  • Caused primarily by cyanobacteria along with sulfide-oxidizing and sulfur-reducing bacteria
  • Most commonly affects massive reef-building corals all over the world
  • Leaves behind bleached coral


Red band disease

  • Narrow bands of filamentous cyanobacteria
  • First type, RBD-1, closely resembles BBD except that bands are maroon in color
  • Second type, RBD-2, has cyanobacterial filaments spread like a net over colony's surface
  • Microbial mat is easily dislodged from surface of coral tissue
  • Affects massive and plating stony corals, and also sea fans throughout the wider Caribbean
  • Leaves behind bleached coral


White Band Disease


White Plague Disease


Yellow Blotch Disease
