Meiofauna are referred to metazoans,including some protozoans,that can pass through sieves between mesh size of 1 mm( or 0.5 mm) and 0.042 mm( or 0.031 mm). Meiofauna are one of the most important components of the benthic ecosystem and serve as a key link in the benthic food web. They are ubiquitous in nature,with short generation time,small body size and high metabolic rates. Thus their metabolic activity has a direct effect on the rate of matter and nutrient recycling within the benthic ecosystem. Althou...
