Abstract:
There are many modifications of eye shape and structure among fish, the general plan is similar throughout. This study was performed to comparative investigation for the lens shape and the interlocking pattern of lens fiber in genus Zacco (Z. temmincki and Z. platypus) and Pseudogobio (P. esocinus). The equatorial and axis diameter of lens for the classification of lens shape were measured by micrometer. And the interlocking patterns of lens fibers were observed by scanning electron microscopy (SEM). The lens shapes of Z. platypus and Z. temmincki were spherical (axis /equqtorial diameter = 1), but the lens shape of P. esocinus was subspherical type (axis / equqtorial diameter = 0.87). The interlocking patterns of lens fibers showed that Z. temmincki have an "anchor and socket" connection, Z. platy-pus have a "ball and socket" connection, and P. esocinus have a "rod and socket" connection. The results of this study may be utilized in the taxonomic keys for the classification of fish.
