Title On some eye-abnormalities in the Malabar sole,
Cynoglossus macrostomus Norman
 
Creator Seshappa, G
 
Subject Fish Diseases
 
Description In a previous note (Seshappa, 1970) the present author has described a specimen
of Cynoglossus semifasciatus Day with the right eye on the ' blind ' side of the
head, almost in the original unmetamorphosed symmetrical position, and the left
eye in its normal adult position on the coloured side of the body ; this is apparently
the first instance of this kind recorded for any flat-fish in the Indo-Pacific region.
Two more such specimens with the eyes situated in positions similar to the above
have been since discovered. Also a large number of instances of eye-abnormalities
of various degrees have been noticed by the author so far in the routine collections
of this species examined during the years 1965-69. As the position of the eye and
its migration form a very important part of the metamorphosis in the flatfishes,
these specimens have been examined in some detail and the present paper gives an
account of the results of these studies together with a discussion of the probable
significance of the various abnormalities noticed.
