摘要

对深海肠虫 Quatuoralisia mala-khovi 的消化系统进行了解剖研究。研究表明，侧领唇的扭曲方式形成了一个纤毛沟，通向一个内部通道，收集到的碎屑颗粒通过该通道转移到咽部外围通道。所选颗粒的大小从 1-6 微米到 100-200 微米不等，这与捕食浮游硅藻残骸的情况相符。观察到一条粪绳在捕食过程中起到了锚的作用，将水量很大的水母状体固定在海底。

Digestive System Anatomy and Feeding Mechanism of Quatuoralisia malakhovi (Hemichordata, Torquaratoridae).

The digestive system was anatomically studied in the deep-sea enteropneust Quatuoralisia mala-khovi. It was shown that lateral collar lips are twisted in such a way that they form a ciliary groove that leads to an internal channel, through which collected detritus particles are transferred to peripheral pharyngeal channels. The size of the selected particles ranges from 1-6 to 100-200 μm, which corresponds to feeding on the remains of planktonic diatoms. A fecal cord was observed to act as an anchor that holds the heavily watered jelly-like body of Torquaratoridae at the sea floor during feeding.
