Flow velocities through and immediately adjacent to the excurrent openings (oscula) were measured in eight species of marine sponges in their natural environments with a two-channel thermistor flowmeter. Flow through the oscula was positively correlated with both normal and artificially augmented ambient flow in both normally pumping and inactive animals. These results indicate that the passage of water through these sponges is, in part, induced by ambient currents.
使用双通道热敏电阻流量计，在自然环境中对八种海洋海绵动物的出水孔及其紧邻区域的流速进行了测量。在正常抽水的和不活动的动物中，通过出水孔的水流与正常的和人为增强的环境水流均呈正相关。这些结果表明，水通过这些海绵动物的过程部分是由环境水流引起的。
