本文报道了欧洲鳗鲡嗅觉器官的形态、解剖和组织学特征。结果发现，每个嗅室开放外部的前入口和后出口鼻孔。各室中的嗅丛呈椭圆形，其嗅叶数目随体长的增加而增加。嗅上皮由感受细胞、支持细胞、基底细胞和杯状细胞组成。平均嗅觉表面积约为视网膜面积的590.9%。因此A.欧鳗是一种大嗅觉的“鼻鱼”，嗅觉在其食性中起着重要作用。注意到A.欧洲鳗（底部饲养者）仅由杆状细胞组成。
The morphology, anatomy and histology of the olfactory organ of Anguilla anguilla have been described. It was found that each olfactory chamber opens externally by an anterior inlet and posterior outlet nostrils. The olfactory rosette situated in each chamber is oval and the number of its olfactory lamellae in the olfactory rosette increases with the increase of body length. The olfactory epithelium of the lamellae is composed of receptor, supporting, basal and goblet cells. The average olfactory surface area is about 590.9% of the retinal area. Thus A. anguilla is a macrosmatic species "nose-fish" in which olfaction plays an important role in its feeding habit. It is noticed that, the photoreceptor cell layer in A. anguilla (bottom feeder) is made up only of rod cells.
