描述了冰岛四种桡足动物的畸形形态。在半咸水鱿鱼类Eurytemora velox （LILLJEBORG, 1853）中，这些异常导致雄性在第五腿上出现额外的肢和节，并且在研究人群中出现的频率相对较高。独眼花属、副眼花属和棘眼花属三种圆锥体的畸形主要影响其分形支及其纹饰。所研究标本的这些变异可能是由于特定的环境因素造成的突变。
The teratological morphology in four copepod species from Iceland is described. In the brackish calanoid Eurytemora velox (LILLJEBORG, 1853) these abnormalities result in the appearance of additional seta and articles on fifth legs in males, and are with relatively high frequency in the studied population. The abnormalities in the three cyclopoid species from genera Eucyclops, Paracyclops and Acanthocyclops affect mostly the furcal rami and their ornamentation. These variations in the studied specimens are probably mutations due to the specific environmental factors.
