Abstract

Bright yellow lenses were found in the eyes of the stomiatoid deep-sea fish, Malacosteus niger Ayres. The optical properties of the yellow lens and the retinal specializations in the eyes were examined. Absorption spectra of the yellow lens revealed two peaks at wavelengths 425 and 460 nm. The photoreceptors were all rods and were arranged in two superimposed layers. An astaxanthin-type retinal tapetum was observed in the pigment epithelium. Some chemical evidence is presented showing that the tapetal material is an astaxanthin ester. The ecological significance of the yellow lens is discussed in connection with that of Malacosteus' orbital light organ which has a reddish filter.

摘要

在深海的裸鳔鱼（Malacosteus niger Ayres）眼中发现了亮黄色的晶状体。对黄色晶状体的光学特性以及眼睛中的视网膜特化结构进行了研究。黄色晶状体的吸收光谱在波长425纳米和460纳米处显示出两个峰值。光感受器均为视杆细胞，排列成两层叠加的结构。在色素上皮中观察到一种虾青素型视网膜反光层。提供了一些化学证据表明反光层物质是一种虾青素酯。结合具有红色滤光片的裸鳔鱼眼眶发光器官，讨论了黄色晶状体的生态意义。
