在实验室培养中，用光学显微镜和电子显微镜测定了作为食物的阿耳特米亚（卤虾）的命运。猎物与有孔虫根茎之间的接触会导致直接的依恋。分泌黏附物质，根足侵入猎物的缝隙。穿透角质层下，开始破坏猎物组织。一些组织团块和细胞被移出，并在试验外开始消化，这是由溶酶体酶包围着部分降解的猎物组织，在根茎周围形成的空间内。被移出的猎物组织被隔离在食物液泡中，并被携带到壳内细胞质中，在那里也发生消化。消化酶是由高尔基体在膜结合囊泡（溶酶体）中分泌的，这些溶酶体贯穿细胞质并与食物液泡融合产生消化。被消化的猎物的甲壳或角质层被丢弃，未消化的废物被残留在空泡中。
The fate of Artemia (brine shrimp) nauplii offered as food to Hastigerina pelagica in laboratory cultures was determined using light and electron microscopy.Contact between prey and foraminiferal rhizopodia leads to immediate attachment. Adhesive substance is secreted and rhizopodia invade crevices of the prey. penetrate beneath the cuticle, and begin disruption of prey tissue. Some tissue masses and cells are dislodged and digestion is begun outside of the test as indicated by lysosomal enzymes surrounding partially degraded prey tissue within spaces created by surrounding rhizopodia. Dislodged prey tissue is sequestered into food vacuoles and carried into the intrashell cytoplasm where digestion also occurs. The digestive enzymes are secreted by the Golgi apparatus in membrane-bound vesicles (lysosomes) which are carried throughout the cytoplasm and fuse with the food vacuoles to produce digestion. The carapace or cuticle of digested prey is discarded and undigested waste material in residual vacuoles i...
