浮游动物

And Octopus ocellatus belongs to zooplanktons -benthos type.

短蛸属浮游动物和底栖生物食性类型。

It is said that millions of sardines migrates from cold sea area for spawn in Capetown to the east for zooplanktons to prey. However, what wait for them are armies of predators, including of porpoies, doradoes, sharks, sea dogs and whales. Some solans and sea-gulls also dive into the sea to attempt to prey sardines, but sometimes they themselves become victims of sharks.

据悉，每年数以百万计的沙丁鱼将从开普敦较冷的产卵水域向东迁徙寻找浮游动物为食，然而等待它们的却是一群猎食大军，其中包括：海豚、剑鱼、鲨鱼、海豹和鲸，在水面之上还有塘鹅和海鸥盘旋着，试图寻找机会潜入水中捕食沙丁鱼，但有时潜入水中的鸟类也会成为鲨鱼的捕食对象。

Species of zooplanktons were identified in Huangjiahu Lake (31 protozoa, 39 rotatoria, 13 cladocera, 5 copepod).

随着湖泊水草生物量的增加，浮游动物的多样性指数也随之而增加。

Results showed that 57 species in total were identified. Among them copepod was the dominant group, containning 20 taxa. The zooplankton community was composed of 18 rotatoria species, 8 cladocera species, 2 tunicata species, and 1 species in each of Protozan, polychaeta, heteropoda, medusae and euphausiacea, and 2 species unidentified.

经鉴定有浮游动物57种，其中桡足类占优势，有20种；其次为轮虫和枝角类，分别为18和8种；此外，被囊动物2种，原生动物、多毛类、异足类、水母类、糠虾类各1种；还有阶段性各种幼虫以及未知种类2种。

The plant floating-bed technology application in Miaojia river showed that the water quality of the plant foating-bed technology applied had preceded evidently than the comparing water, though the water quantity was exchanged largely. There existed a micro-ecosystem at the root aera of floating-bed plant which mainly consists of organic grain, algae, zooplankton, zoobenthos. The mode of "Oenanthe javanica -Ipomoea aqutica" floating-bed mode application realized the whole year run of plant foating-bed technology on polluted water. Hence, the mode is suggested in the following application.

植物浮床技术在苗家河的示范应用研究说明：在水量交换较大的情况下植物浮床技术仍然使示范河段水质优于对照段；浮床植物根际区存在着以有机颗粒、藻类、浮游动物、底栖动物为网络骨干的根系微生态系统：&水芹菜-水蕹菜&浮床模式可实现四季净化污染河水的周年运转，在后续应用中推荐使用此模式。

Though corals get most of their food from the byproducts of zooxanthellae algae's photosynthesis, they also have barbed, venomous tentacles they can stick out, usually at night, to grab zooplankton and even small fish.

虽然珊瑚类得到很多它们的食物从副产品的动物黄藻类的光合作用，它们也有刺，有毒的触须能够粘住不放，通常在晚上，去夺取浮游动物和甚至小鱼。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
