Bleaching occurs when corals expel their symbiotic zooxanthellae - pigmented, algae-like protozoa that live within the coral's cells. High temperature, pollution or other stresses can cause the coral to expel its zooxanthellae, leading to a lighter or complete loss of color.
Other impacts may sometimes be seen on coral reefs. These include evidence of bomb or cyanide fishing, sedimentation, pollution or trash
