KITAZATO, HIROSHI（静冈大学地球科学研究所）。 1989.沉积物内底栖有孔虫的垂直分布（初步报告）。底栖动物研究（Bull.Jap.Assoc.Bethology），35/36：41-51。我分析了沉积物内底栖有孔虫的垂直分布。样本是从面向日本中部的太平洋采集的。我还在实验室培养了近海到中深海的底栖有孔虫以进行生态观察。底栖有孔虫在沉积物内垂直分层。底栖有孔虫物种的表层生活习性和动物体内生活习性均得到认可。生活习性相同的有孔虫，其外壳性状相似，细胞质颜色也相似。表面栖息的有孔虫具有低矮的转轴螺旋或平面螺旋室排列，并且还具有厚而坚固的室壁。生活在沉积物中的有孔虫具有较高的转轴螺旋测试。它们有薄而透明的室壁。透过室壁的细胞质呈黑色。这些物种的细胞质中可能存在共生体。
KITAZATO, HIROSHI (Institute of Geosciences, Shizuoka University). 1989. Vertical Distribution of Benthic Foraminifera within Sediments (Preliminary Report). Benthos Research (Bull. Jap. Assoc. Benthology), 35/36: 41-51. I analyzed the vertical distribution of benthic foraminifera within sediments. Samples are collected from the Pacific, facing to the Central Japan. I also cultured sublittoral to middle bathyal benthic foraminifera in laboratory for ecological observations. Benthic foraminifera are vertically stratified within sediments. Both epi-and infaunal life habits are recognized among benthic foraminiferal species. Foraminifera belonging to the same life habits have similar shell characters, and have similar colours of cytoplasm. Surface dwelling foraminifera have low trochospiral or planispiral chamber arrangements, and also have thick and strong chamber walls. Foraminifera which are living within sediments have high trochospiral tests. They have thin, transparent chamber walls. Cytoplasm through chamber wall shows black in colour. It is probable that these species have symbionts in their cytoplasm.
