Coral Bleaching is the lack of color on various types of coral. This colorlessness is due to the death of the coral's symbiotic partner, the zooxanthellae algae. As the algae provides the coral with most of its color, the death of these creatures can prove quite detrimental to the life of corals. While some corals can live for short periods of time without their zooxanthellae partner, the majority of events that result in loss of zooxanthellae also result in death for the corals. Apart from these direct consequences that bleaching events have on the coral themselves, the stark white environment the bleaching creates can also render the area unsustainable for the otherwise vibrant fish. The white backgrounds create an environment that don't allow the fish to camouflage themselves to hide from predators as well as stalk prey. | |||

The Role of Color on the Reef
Introduction
Fish vision
Rods and cones
Different from humans[1]
Broad color spectrum picked up
UV visual sensitivity
communication signals[2]
Fish Coloration
Specific colors and patterns
blue, red, orange, yellow, green, gray, white, black, brown, silver[3]
brightness
bands, stripes, bars, speckles, spots, lines, blotches, eye markings, ocellated spots
The Role of the Environment in Coloration
Depth, temperature, etc
Roles of Colors
Protection Against Predation: warning colors, camouflage
[4]
Mate Selection
Life cycle phases
purpose of color as a juvenile vs. adult[5][6]
specific examples: Queen Angelfish, Schoolmaster, Dusky Damselfish
Polymorphism
Permanent color variations in species (geographical)[7]
Color and marking phases
temporary changes to enhance camouflage, to indicate mood, or for intraspecies communication (courtship)
instantaneous or over a long period of time
Bioluminescence
brief description and purpose
Coral Coloration
The role of the Environment on coloration
Depth, sedimentation, etc
Symbiotic relationship with algae
algae give coral its color
Fluorescent proteins
give color to algae[8]
cyan, green, yellow, red, purple-blue, chromo-red
Coral Bleaching
mainly focus on effects of lack of color
