title: Multiple optic fiber patterns in the catfish retina.
abstract: The retinas of certain catfish contain multiple optic discs. This report describes the patterns of optic nerve fibers and optic discs as seen in silver-stained flat mounts, in 11 different families of catfish. As many as 50 optic discs may exist in a single retina, in paired and unpaired combinations, and in slit and ring-like arrays.
