benthic

1.Benthic meiobenthos is one of the most important community to biomedical research.

深小型底栖物具有重要物医学研究价值。

2.In the stream with strong bed load movement there is no benthic macroinvertebrate.

乱且床运动剧烈支流物种丰度和密度均很低甚至为零，态条件差。

3.Closely associated with the benthic community are organisms collectively called periphyton or aufwuchs.

但是当水变浅时，物相会改变。
