An interesting case of an adult sole (Cynoglossus semifasciatus Day) with a normal eye on the ' blind 'side of the head

Abstract

It is well known that a very important phenomenon accompanying the metamorphosis in the Flatfishes (Heterosomata) is the migration of one of the eyes of the symmetrical larva to the opposite side so that ultimately both the eyes are on the same side of the body namely, the coloured side. In the case of the Malabar sole (Cynoglossus semifasciatus Day) Seshappa and Bhimachar 1955 have described the various stages in the migration of the eye, the migrating eye being that of the right side.
