刺冠海星更偏好分枝的珊瑚。
一只棘冠海星每年可以吃掉5到6平方米的珊瑚虫。
A single Acanthaster can consume five to six square meters of coral polyps per year.
当刺冠海星爆发时，它们会使快速生长的珊瑚变薄，并可能给生长缓慢的珊瑚一个重新生长的机会。
When an outbreak of CoT starfish occurs, they thin out the fast-growing coral and may give the slower ones a chance to reestablish.
刺冠海星是一种以珊瑚虫为食的珊瑚礁捕食者。
The crown of thorns starfish is a coral reef predator that preys on coral polyps.
现在，让我们来看一个自然捕食者的具体例子，它会对珊瑚礁造成很大的伤害——那就是刺冠海星。
Now let's focus on a specific example of a natural predator that can cause a lot of damage to coral reefs—the Crown of Thorns, or CoT starfish.
刺冠海星生活在热带太平洋的珊瑚礁上，以珊瑚为食。
The Cot starfish is found on coral reefs in the tropical Pacific Ocean and it eats coral.
幸运的是，刺冠海星的数量渐渐地自发减少了，珊瑚礁也恢复了。
Luckily, the CoT starfish population gradually declined on its own and the reefs recovered.
年幼的刺冠海星在出生后的第一个月就以浮游植物为食，所以海洋中肥料越多，浮游植物就越多，也意味着海星越多，这对珊瑚礁非常不利。
Larval CoT starfish eat phytoplankton in their first month of life, so more fertilizer in the ocean means more phytoplankton, which means more starfish, bad for the reefs.
其他对于大堡礁及其生态系统的环境压力来自径流的水质问题，伴随着大规模珊瑚白化的气候变化以及棘冠海星的周期性爆发现象。
Other environmental pressures to the reef and its ecosystem include water quality from runoff, climate change accompanied by mass coral bleaching, and cyclic outbreaks of the crown-of-thorns starfish.
棘冠星鱼会捕食珊瑚虫，大量的海星会摧毁珊瑚。
The crown-of-thorns starfish preys on coral and large outbreaks of these starfish can devastate reefs.
此处讨论的加勒比海珊瑚礁在20世纪80年代中期遭受沉重打击，当时一种神秘疾病几乎使冠刺棘海胆(Diademaantillarum)灭绝。
The Caribbean coral reefs in question were dealt a blow in the mid 1980s when a mysterious disease almost completely wiped out the spiny urchin (Diadema antillarum).
