A single Acanthaster can consume five to six square meters of coral polyps per year.
一只棘冠海星每年可以吃掉5到6平方米的珊瑚虫。
The destruction of coral through land use activities would cause a decrease in the number of predators that feed on Acanthaster larvae.
通过土地利用活动对珊瑚的破坏会导致以棘星幼虫为食的捕食者数量减少。
It is difficult to understand how reduced predation would lead to sudden increases in Acanthaster numbers in several places at the same time in specific years.
