The study history of cave invertebrate in China is summarized in this paper. We list new species of Chinese troglobiotic invertebrate found over the past twenty years, and two types of cave invertebrate are divided according to the differences of the habitat: terrestrial community and aquatic community. The review also emphasizes the current research on Arachnolida, Diplopoda, Insecta, Crustacea and Castropoda.

Biological Activated Carbon Filter could provide ideal habitats for invertebrates, but invertebrates may lead to aesthetic problems and adverse health effects of drinking water. This paper studied the invertebrates in biological activated carbon filters in a water plant of the south of China during Sep. 2006 to Sep. 2007. The results implied that BAC filters were colonized by invertebrates, in which 23 species of invertebrates were found, the dominating organism group was the rotifer, and others included Copepoda, Cladocera, Oligochaeta, Nauplii and Nematoda.

生物活性炭(Biological activated carbon， BAC)滤池能够为无脊椎动物提供理想的生境，但无脊椎动物可能给饮用水带来负面的健康效果和感观问题。2006年9月～2007年9月，对南方某水厂BAC滤池无脊椎动物滋生状况进行了为期13个月的调查研究，共发现无脊椎动物23种，优势类群为轮虫，其他类群还有桡足类、枝角类、寡毛类、无节幼体、线虫等。

BIOLOGIST: For example the Tuatara and the night frogs, the flightless crickets and these incredibly bizarre forms, it's a mere sized invertebrate with tast on it which only comes out at night and eats other invertebrates, saucer sized predatory snails, earthworms we meet a lot, things like the Moana kiwi.

生物学家：例如大蜥蜴和夜蛙，不能飞的蟋蟀以及有着不可思议的奇怪外型的动物，它是一种小型的无脊椎动物，只在夜间活动，捕食其他无脊椎动物，茶托状的食肉蜗牛，蚯蚓是常见的动物，还有摩阿纳鹬鸵。

Because the sex determination of Bombyx is a model of epistatic systems in inverteberates, the clarification of the sex-determining mechanism of this insect would be helpful for a comprehensive understanding of sex determination in invertebrates.

家蚕的性别决定是无脊椎动物中的一个上位体系模式，因此，家蚕的性别调控机制研究将有助于理解无脊椎动物复杂的性别调控机制。
