Analyses of various marine polychaete worms (phylum Annelida) reveal that members of the family Nephtyidae are exceptional in containing very high concentrations of calcium and phosphorus. We report here that in the genus Nephtys, the two elements form rounded granules packing the sarcoplasmic core of obliquely striated muscle cells. Intracellular calcium granules rich in phosphorus are found throughout the animal kingdom and occur in a wide range of tissues. Although some examples of granules in muscle tissue have been recorded (as in Syllis proventriculus), as far as we are aware, none appears in the abundance found in Nephtys.
对各种海洋多毛类蠕虫（环节动物门）的分析表明，海蛹科成员在含有极高浓度的钙和磷方面表现突出。我们在此报告，在海蛹属中，这两种元素形成圆形颗粒，填充在斜纹肌细胞的肌浆核心中。富含磷的细胞内钙颗粒在动物界广泛存在，见于多种组织。尽管已经记录到肌肉组织中有一些颗粒的例子（如在Syllis proventriculus中），但据我们所知，没有一种像在海蛹属中那样大量存在。
