Researchers have disproven the secondary outbreak hypothesis in the Central Pacific. One of the greatest biological threats to tropical coral reefs can be a population outbreak of crown-of-thorns (COT) sea stars (Acanthaster planci). Outbreaks can consume live corals over large areas, a change that can promote algal growth and alter reef fish populations.
