Research Abstract |
Most organisms living in underground lake in caves have their eyes degenerated. On the other hand, why do organisms living in the deep-sea environment keep the eyes even though they reside in the same darkness for much longer periods of time than those in the underground lakes? Are their eyes really functional? Answer of the question was indicated from the research conducted here. The study results have indicated that the deep-sea fish, Malacocottus gibber, had recognized the objects readily with their eyes. The fish exhibited to be able to learn and discriminate the several colors in the darkness. Moreover, the deep-sea anemone, which is known to be a primitive organism and does not form the eyes, was aware of a light with recognizing the change of wavelength.
