管水母行为对其自然饮食的影响：攻击性模仿的证据

潜水员的收集可以确定 II 属管水母物种的天然饮食。管水母能快速游动以张开触手捕获小型猎物，而那些游动非常微弱的管水母则捕获更大的猎物。两种游泳能力较弱的物种的线囊电池与桡足类和鱼类幼虫非常相似。形态、行为和饮食表明这两个物种通过模仿其他浮游动物来吸引大型猎物。
Collection by divers permitted determination of the natural diets of siphonophore species within II genera. Siphonophores that swim rapidly to spread their tentacles capture small prey, whereas those that swim very weakly capture much larger prey. Nematocyst batteries of two species of weak swimmers closely resemble copepods and fish larvae. Morphology, behavior, and diet suggest that these two species attract large prey by mimicking other zooplankton.
