A biophysical, morphological and morphometrical survey of the eye of the small shark (Hemiscyllium plagiosum).

The biophysical and morphological characteristics of the small shark's ( Hemiscyllium plagiosum ) eye were studied. The focal lengths of the lens were found to be very short. A small proportion of cones were present in the retina and this proportion varied with the weights of the sharks. The topographic distribution of cones in different segments of the retina was also presented.
