珊瑚是一种奇妙的海洋生物,它是动物却有着植物的功能,它像动物一样靠精卵结合生殖,他像植物一样出芽、分裂繁殖,它生长在温暖、清澈的海底。小小的珊瑚虫可结成群体,形成“岛屿”。别看它的构造是这样的简单,连免疫系统都没有,但它们化学防御能力却大得惊人。 Coral is a fantastic marine life. It is an animal that has the function of a plant. It reproduces like an animal by sperm and egg. He buds and splits like a plant and grows in a warm, clear sea. Small polyps can form groups, forming “islands.” Do not look at it's structure is so simple, even the immune system are not, but their chemical defenses are staggering.
