研究了13种中华绒螯蟹的栖息地深度、眼径与体长的关系以及眼径与眼径、眼径与眼径、眼径与眼径的关系。3个大洋磷虾属[Euphausia superba，E. pacifica、E. gibboides、Thysanopoda cristata、T. tricuspidata，T. aequalis，T. monacantha，T. orientalis，T. pectinata、T. acutifrons，尖额毛叶蜂T. cornuta，T. egregia和Bentheuphausia amblyops]，栖息地从近地表沃茨到深海。眼睛的生长速度随深度而降低。较长的横纹肌可能会增加特定尺寸和深度的眼睛对点光源和扩展光源的视觉敏感度。较大的眼间角提示视敏度随深度的增加而降低。与深度有关的变化，euphausid眼睛被认为是在深海中的视觉和生物发光的可能作用。描述了几个物种的眼睛的不寻常的功能。
The relationships between habitat depth, eye diameter relative to body length and the dimensions of rhabdoms and crystalline cones were examined for 13 spp. of 3 oceanic euphausiid genera [Euphausia superba, E. pacifica, E. gibboides, Thysanopoda cristata, T. tricuspidata, T. aequalis, T. monacantha, T. orientalis, T. pectinata, T. acutifrons, T. cornuta, T. egregia and Bentheuphausia amblyops] with habitats ranging from near-surface waters to the deep-sea. Rate of eye growth decreases with depth. Longer rhabdoms may increase the visual sensitivity to point and extended light sources by an eye of a particular size with depth. Larger interommatidial angle suggest that visual acuity decreases at depth. Depth-related changes in euphausiid eyes are considered with respect to the probable roles of vision and bioluminescence in the deep-sea. Unusual features of the eyes of several species are described.
