Lugworm (Arenicola marina) Drawings & Dimensions

The Lugworm (Arenicola marina) is a large marine worm. While the animal is rarely seen, its coiled castings are a familiar sight on a beach at low tide. They live in U-shaped burrows in the sand, and they feed on organic material like micro-organisms and detritus in the sediment.

环节动物门海蛭纲中的海蛭（Arenicola marina）乃一类巨型海洋蠕虫。虽其身影难得一见，然其螺旋状的排泄物于潮汐低落之际，常成为海滩上的显著景观。此类生物栖息于U形沙穴之中，以沉积物中的微生物和碎屑等有机物质为食。
