　　Red mangrove roots arch across thousands of Sonneratia alba mangrove root spikes snorkeling up through a mudflat in Kosrae Island, Micronesia.
　　Intricate both above and below ground, mangrove roots hold the plants upright in sodden soil, supply them with air when the tide rises, and, in some species, even remove salt from seawater.

　　在密克罗尼西亚的科斯瑞岛，拱状的美国红树树根盘据在成千上万的杯萼海桑树根之上，笋状的杯萼海桑树根是其在泥滩上的透气管。这些树根无论在地上或是地下都是错综生长的，其使得红树直立在湿透的土壤中，并在涨潮时提供空气，甚至有些种类的树根，还可以将海水中的盐分除去。
