1·The chiton’s pinkbackground camouflages it from predators as it feeds on coralline algae.

在石鳖吃珊瑚线藻时，它的粉色背景起到了伪装作用，使它免遭捕食者伤害。

2·The pink coralline algae is an early sign of recovery: The algae form a substrate on which new coral can attach itself and grow.

粉红色的珊瑚藻是复苏的前期征兆：它们可以形成新珊瑚依附和生长的基质。

3·By grazing on algae, these and other herbivores keep reefs free of seaweed, enabling pink coralline algae to take hold and form a substrate for new coral.

通过啃食藻类，食草鱼类会帮助珊瑚礁清理海草，让粉红珊瑚藻得以扎根，形成新珊瑚生长的基质。

4·Mollusks, crustaceans, and even coralline algae are among theliving things that use calcium in their structures, a process that could beimpeded by higher acidity levels in seawater.

软体动物，甲壳纲动物，甚至珊瑚藻都需在其身体结构生长中用上钙，而海水酸度变高则会阻碍这一过程。
