Variation in the number of layers of the dorsal integument and neuromast size from ceratophryids. Dermal histology in larvae at Gosner stage 37 for a Ceratophrys cranwelli, b Lepidobatrachus laevis, c L. llanensis and d Chacophrys pierottii. The variation in the size of neuromasts in the dorsal lateral line (arrows) seems to be related to integument thickness. In Ce. cranwelli and Lepidobatrachus spp., the epidermis is pluristratified, and the dermis has spongiosum and compactum strata in L. laevis. In C. pierottii, there are only two epidermal layers and a thin compact stratum in the dermis. ho hypodermis, sc stratum compactum, ep epidermis, ss stratum spongiosum. Bar equals 50 μm
