Diversification of body shape in catfishes of the Ganga River

Arvind Dwivedi, Hariom Verma & Saurabh Dewan
Catfishes of the order Siluriformes are an exceptionally diverse group occupying significant fraction of the world's freshwater ichthyofauna. Catfish species renders a model system for phylogenetic and evolutionary studies. However, there is dearth of knowledge on the phylogenetic history with reference to morphological diversity of catfishes in the Ganga River. Geometric morphometrics is an efficient approach to quantify shape variations and has lately found application in range of taxonomic, phylogenetic and evolutionary studies. This study...
