メイオベントス（meiobenthos）

意味

Meiobenthos are the smaller benthos. They are smaller than the more visually obvious macrobenthos (e.g., segmented worms, echinoderms, clams, snails, etc.). Conversely, they are larger than the microbenthos – a term restricted primarily to Protista, unicellular algae, and bacteria. Meiobenthos (benthos=bottom living) refers specifically to those meiofauna that live on or in sediments.
