  • Intraspecific morphological variation and differentiation among six populations of the endemic freshwater fish Puntius singhala (Cyprinidae) were investigated. There is significant sexual dimorphism in three morphometric characters (pectoral-fin length, caudal-peduncle length, and length of dorsal-fin base), where males have slightly longer measures than females, indicating adaptive significance related to dispersal. Significant heterogeneity and differentiation was found only among some of the… CONTINUE READING
