Abstract

Abstract: Scanning electron microscopy (SEM) of scales in six species of the fish genus Channa revealed certain features relevant to taxonomic significance. The location of focus, inter-radial distance and width of circuli, inter-circular space, width of radii, shape and size of lepidonts, etc. were found to be different in different species. The importance of SEM of scales in poorly understood taxonomy and phylogeny of the fish genus Channa is discussed with the help of relevant literature. Further, the role of SEM of fish scales for taxonomic applications is discussed in detail.
