| 摘 要： | 应用光镜及电镜技术研究中国鲎（Tachypleus tridentatus（Leach））复眼的形态和超微结构。结果表明，中国鲎复眼表面覆盖角膜层，外形呈半球形，由800-1200个小眼组成，组成复眼的小眼面均为椭圆形。每个小眼包括透光和感光两部分。透光部分由透光锥体和透光孔径组成；感光部分包括小网膜细胞及色素细胞。小网膜细胞分R-区和A-区，R-区是有感杆束分布的区域，A-区是没有感杆束分布的区域，但A区的表面覆盖着色素细胞，色素颗粒主要分布于A-区和R-区的交界处。8个小网膜细胞排列成的桔瓣状结构组成1个小眼的感光部分。中国水产科学，2006，13（4）：517—524] |

| Abstract: | The morphology and fine structure of the compound eye in horseshoe crab,Tachypleus tridentatus was investigated by using light and electron microscopy.The results indicated that the compound eye of Tachypleus tridentatus consists of 800-1?200 ommatidia;the facet of the compound eye is oval.An ommatidium is composed of transparency area and photonasty area;the transparency area is made up of cuticular cone and aperture,but photonasty area includes retinular cells and a lot of pigment cells.Retinular cell divides into rhabdomeral-segment and arhabdomeral-segment.Rhabdom distributs in rhabdomeral-segment but not in arhabdomeral-segment,moreover pigment cells are covered with arhabdomeral-segment and the majority pigment cells distribute in the join point of rhabdomeral-segment and arhabdomeral-segment.Eight wedge-shaped retinula cells rank radially about the optical axis of the ommatidium like the segment of an orange,which are the morphological and functional units of a compound eye.Journal of Fishery Sciences of China,2006,13(4):517-524] |
| Keywords: | Tachypleus tridentatus Leach compound eye ommatidium retinular cell rhabdom ultrastructure |
