Description

The Eichwald’s toad is very similar to Bufo verrucosissimus, but differs by a longer and more massive head, body proportions, skin texture, coloration, and numerous dark spots on the belly in males. In addition, B. eichwaldi has a head with an abrupt (not acutely rounded) snout tip, uniform dull brown dorsum, parotoid margin (contacting with tympanum) with black markings, and some larger rounded knobs on dorsum a little darker brown than the surface. The Eichwald’s toad differs from B. verrucosissimus by a markedly lower genome size (13.22 â€" 13.36 vs. 13.53 â€" 14.09 pg per diploid nucleus), seven peculiar protein loci, values of indices Lc/L (2.74 â€" 2.81 vs. 3.37 â€" 4.67) and Lc/Ltc (0.94 â€" 0.98 vs. 0.59 â€" 0.88). B. eichwaldi differs from B. bufo by five peculiar protein loci, and values of indices Lc/L (2.74 â€" 2.81 vs. 3.07 â€" 4.51) and Lc/Ltc (0.94 â€" 0.98 vs. 0.61 â€" 0.86).
