Annual dynamics and distribution of three Orthonectida species--Intoshia variabili, I. linei, Rhopalura littoralis--have been studied in the invertebrates in the White and Barents seas. Throughout years of observations orthonectids show high stability, constant percent of infection and permanent location of the same spots. Mosaic pattern of their distribution has been revealed. Possible causes of difficulties in finding orthonectids in nature are discussed.
对白海和巴伦支海无脊椎动物体内的三种直泳虫物种——多变因托吸虫（Intoshia variabili）、林氏因托吸虫（I. linei）、滨海棒吻吸虫（Rhopalura littoralis）的年度动态和分布情况进行了研究。在多年的观察中，直泳虫显示出高度的稳定性、恒定的感染率以及在相同地点的固定分布。揭示了它们分布的镶嵌模式。讨论了在自然界中难以发现直泳虫的可能原因。
