本文对16000多个大型底栖有孔虫（主要是直管状的海盘纲动物Bathysiphon folini和B. rusticus，但也hormosinids和石灰质物种）和外生体从996和4 416米之间的底栖雪橇样品进行了检查的后生动物居民。记录的1011种生物以星虫为主，但也包括线虫、多毛类、桡足类、等足类、端足类、塔奈类和水螅类。卵被观察到，无论是单独或与星虫，线虫，端足类动物，和tanaid。星虫和其他蠕虫在一些样品中占据了11%的深虹吸管和= 20%的高氨管。相反，钙质测试很少居住的后生动物。来自几个半深海岩芯样本的数据表明，少数（约4%）小型底栖生物生活在小型有孔虫试验中，通常是球海胆类。大多数后生动物都是在空的测试中发现的，显然是作为避难所...
Abstract The tests of more than 16000 large, benthic foraminifers (mainly the straight, tubular ammodiscaceans Bathysiphon folini and B. rusticus but also hormosinids and calcareous species) and xenophyophores from epibenthic sledge samples obtained between 996 and 4 416 m were examined for metazoan inhabitants. The 1 011 organisms recorded were dominated by sipunculans but also included nematodes, polychaetes, harpacticoid copepods, isopods, amphipods, tanaids, and hydroids. Eggs were observed, either alone or associated with sipunculans, nematodes, amphipods, and a tanaid. Sipunculan and other worms occupied 11 % of Bathysiphon tubes and = 20 % of Hyperammina tubes in some samples. In contrast, calcareous tests were rarely inhabited by metazoans. Data from several bathyal core samples indicate that a few (about 4 %) of the meiofaunal organisms were living in small foraminiferal tests, usually those of globigerinaceans. Most of the metazoans were found inside empty tests which apparently served as refuge...
