The amphipodGammarus pulex L. displayed aggregative behavior when stimulated by exudates from the isopodAsellus aquaticus L. in laboratory experiments, while the isopod avoided its predator by chemotaxis. Nonvolatile exudates from the amphipod significantly increased the respiration rate of the isopod. Exudation of free amino acids was greatly enhanced when both species were present in the same water, and it was calculated that the increased exudation by the prey was equivalent to a loss of 4-5% of its assimilated energy.
在实验室实验中，当受到水生等足目动物Aquilus aquaticus L. 的分泌物刺激时，片脚类动物蚤状溞Gammarus pulex L. 表现出聚集行为，而等足目动物则通过化学趋性避免其捕食者。非挥发性分泌物显著增加了等足目动物的呼吸速率。当两种生物在同一水中存在时，游离氨基酸的分泌大大增强，据计算，猎物增加的分泌量相当于其同化能量的 4-5%的损失。
