测定了S.在马萨诸塞州的葡萄园湾（Vineyard Sound）饲养的秀丽隐杆线虫（elegans），在0°C的温度下，通过将从实验室观察获得的消化时间（10.2 h）应用于肠内容物的分析。大型个体的比日摄食量约为体干重的1-2%，小型（3.5 mm）的约为46%。除了最小的动物外，所有动物的摄食率都与呼吸数据预测的相似;最小的个体消耗超过其估计的无生长需求。
Feeding rates were determined for S. elegans feeding in Vineyard Sound, Massachusetts, at a temperature of 0°C by applying a digestion time (10.2 h), obtained from laboratory observations, to an analysis of gut contents. The specific daily ration of large individuals was about 1–2% of body dry wt·d−1, that of small chaetognaths (3.5 mm) was about 46%. Feeding rates for all but the smallest animals are similar to those predicted from respiration data; the smallest individuals consumed more than their estimated no-growth requirements.
