Boreal toad

Boreal toads lack a cranial crest, and can be distinguished from the other western toad subspecies, the California toad, by looking at its underbelly, which is covered by a considerable amount of dark blotches. Adult males on average are between 2.4–3.1 inches and females are 2.9–3.9 inches Their coloration can range from brown to green and they have a distinct white middorsal stripe. Both sexes have dry, warty skin and oval parotoid glands. Male boreal toads have no vocal sac, and therefore have no mating call.
