Abstract
This study utilizes photographs of 39 Gangetic catfishes to evaluate inter-specific phenotypic relationship through Geometric Morphometrics (GM). Permutational multivariate analysis of variance (PERMANOVA) revealed significant relationship (F = 4.50, p < 0.0001) between shape of all the species. Procrustes analysis of variance (ANOVA) revealed significant relationship between shape and size (F = 17.67, p < 0.0001) and between shape (F = 34.95, p < 0.0001) of all species. Morphospace phenogram depicted that all the species under respective genus clustered together within that genus, indicating that species of respective genus share common phenotypic traits and have evolutionary relatedness, affirming the implication of geometric morphometrics in showcasing phenotypic relatedness among Gangetic catfishes. This study has high implications for understanding the ecological and evolutionary problems in relation to morphological diversity in catfishes.
