补充资料：海洋线虫
| 海洋线虫 marine roundworm 海洋中自由生活的线虫的通称 。属 于线虫动物门的无尾感器纲，分布在从潮间带直到大洋深沟的沉积物中，或附着在海藻和有机质碎屑的表面。已有可靠记录的海洋线虫有4000种。 身体为细长梭形或圆柱形。大多数种体长在1毫米以内，某些大型种长达5毫米甚至更长。海洋线虫以尾腺的分泌物粘附在各种类型的基质上，头端游离取食，更多的种类在砂间内自由生活。头部顶端为口，周围有6个唇瓣，每侧3个。头部和体部刚毛较习见。某些种类头部角皮的内层加厚形成头鞘。雌性末端横裂即为肛门，开口于尾端腹面。雄性则膨大形成泄殖腔。通常为雌雄异体，雄体略小，尾部向腹部弯曲。生殖时有交配现象。海洋线虫产卵一般不超过50个。排泄系统退化为单一的大型细胞腺。 海洋线虫为底栖，大致可分为河口和半咸水、潮间带、浅海和深海等4个群聚。栖息密度为后生动物之冠。以底栖硅藻和沉积物颗粒表面的细菌、真菌及其有机碎屑为食。某些为肉食性（杂食性）种类。 海洋线虫是线虫动物门中最原始的成员，现有6个目。它们是：薄咽目、项链目、单宫目、链环目、色矛目和嘴刺目。 |
