Fig. 6 in Nuptial pads of rock frogs (Thoropa, Cycloramphidae, Anura): How papillary epidermal projections are related to sexual maturity and taxonomy

Fig. 6. Violin plots of the number of papillary epidermal projections (PEPs) on the left metacarpal-phalangeal articulation of finger II (MPA-II), the left inner metacarpal tubercle (IMT), the left whole finger II (M II + P-II), and the left finger III, grouped by species, with corresponding Kruskal–Wallis H statistics and Pvalues. The sample size is given below the species names.
