Abstract

|
|
|
Most spiders have four pairs of simple eyes. A few families of the spider have their developed eyes to an extent visual cues make up a significant of information to response from the external stimuli. Most spiders respond to the external stimuli around them. Specially, they are very sensitive to vibrations from the air, the ground, their webs, or even the surface of water. The present study was undertaken to examine the evolutionary development and function of eye with the observation of visual ultrastructure of Atypus coreanus Kim, 1985 using the electron microscopy. They have weak mobility, limited territory and low developed eyes. Atypus coreanus was collected from Mt. Ungil, Namyangju-gun, Kyonggi province. The fine structure of these eyes was examined by electron microscopy, and prepard by teasing method for scanning electron microscopic observation. As a result, the eyes of Atypus coreanus was composed of cornea, lens, vitreous body, retina, and rhabdome.
