綠巧言蟲（學名：Eulalia viridis）是葉鬚蟲目葉鬚蟲科巧言蟲屬之下的一個多毛綱物種[4]，有著亮綠色的外表。本物種長約5至15 cm（2至6英寸）。在北大西洋海域，見於歐洲的挪威、英國及愛爾蘭[1]的淺海或貽貝床[5][6]。
其種加詞「viridis」意為「綠色的」。

形態描述
巧言蟲是一種背部扁平又纖細的蠕蟲，有體節高達200節。蠕蟲最長可以生長至15 cm（6英寸），顏色從中綠色到亮綠色。頭部有五條觸角、兩隻眼及四對tentacular cirri；the eversible proboscis is cylindrical and dotted with rounded papillae. Each body segment has a pair of parapodia, and the cirri on these are long, thin and pointed. They project outwards, forming a fringe down each side of the body.[7]
分佈及棲息地
1990年代以前，巧言蟲被認為遍佈東北大西洋，包括環繞英國的水域[1]，但形態學及生物化學研究表明在分佈於南部的物種應屬另一物種，即Eulalia clavigera；而這兩個物種形成了一個生物複合種[8]。
As now recognised, E. viridis is native to the northeastern Atlantic Ocean where it is found in the waters off Norway, Sweden, Denmark and Germany, as well as the 法羅群島, Iceland and 迪斯科島 at depths from the mid-shore down to about 150米（500英尺）. It is typically found on rocky coasts and on shelly gravel,[9] in rock crevices and 無孔貽貝 beds.[7]
主要分佈於在中國分佈於山東半島、遼東半島[10][11]、黃海、東海、南中國海[1]，還有白海、新西伯利亞群島、白令海、千島群島、勘察加半島、鄂霍次克海、日本海等海域[1]。 一般棲息於北方和亞熱帶水域以及主要棲息於潮間帶和潮下帶海藻、藤壺、牡蠣及海鞘等附著動物和岩石下[1][5][6]。其生存的海拔下限為-2400米[1]。

生物學
Although many worms in this family are 捕食 and actively hunt prey, E. viridis seems to be more selective in its diet, and researchers found that it only consumed moribund or dead animal tissue. Breeding does not take place until the worms are at least two years old, and they are not thought to form swarms as do some other related species.[12] The greenish gelatinous egg mass is attached to 褐藻綱, but some populations seem not to have egg masses. The larvae pass through one or two 擔輪幼蟲 stages and two other stages before settling on the sea bed as a five- to nine-segmented larva, after up to nine weeks.[12]
