Coral Disease
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
