When a coral colony is destroyed, it removes wildlife in the area and makes preservation almost impossible in the ...
The most common way to tell if a coral is healthy is by looking at its coloration. A dead or unhealthy coral will be bleached, which means they have 40%-50% or more of their pigmentation missing. [7] Some coral diseases take the form of a narrow band of diseased tissue separating the living tissue from the exposed skeleton.
Coral-associated fish populations tend to be in decline due to habitat loss; however, some herbivorous fish populations have seen a drastic increase due to the increase of algae colonization on dead coral. [173] Studies note that better methods are needed to measure the effects of disturbance on the resilience of corals. [168] [174]

[1] The spotted area distinguishes skeletal eroding band from black band disease, [1] which also forms an advancing black band but leaves a completely white dead area behind it.

Due to the loop of hypoxia and coral reef mortality, the fish and other marine life that inhabit the coral reefs have a change in behavioral in response to the ...
