The tiny microscopic animals that secrete this polypary live by the billions in the depths of their cells.

这些以分泌物累积成珊瑚树的细小微生动物，是数以亿万计地生活在细胞里面。

A coral is a unit of tiny animals assembled over a polypary that's brittle and stony in nature.

珊瑚是一群聚集在易碎的和石质伪珊瑚树上的微生物的总体。

For some it's a polypary, and for others, such as Professor Milne-Edwards, it's a single, solitary individual.

另外一些，像爱德华先生，却认为它是独立的、单一的个体。

The sponge is definitely not a plant, as some naturalists still believe, but an animal of the lowest order, a polypary inferior even to coral.

海绵并不是植物，像现在还有些… 生物学家承认的那样。它是动物，不过是最低一目的动物，是比珊瑚更低的水熄丛。
