starts withSpecimens range from 28–56 mm, typically weighing between 2.3 and 12 g. This places them among the smaller members of the family Bombinatoridae, which can reach sizes of 7 cm. Their top side is grey-brown, often with washed-out, bright spots. Their under side, including the inner sides of the limbs, fingers, and toes, is grey-blue to black-blue with striking, bright yellow to orange spots or patches, usually covering more than half of the underside. Yellow-bellied toads have compact bodies - though not so flat as the related European fire-bellied toad - and a rounded snout. The pupils are heart-shaped, with the eardrums not visible. The overside has numerous warts with raised swirls. A study conducted by researchers from Brill Academic Publishers had concluded that there are sexually dimorphic differences noted within the species. Males of the species have notably longer humerus length resulting in a longer forelimb length; It is believed to give them an advantage while coupling and while fighting other males of the same species.
The yellow-bellied toad is an amphibian closely bound to areas of water. Originally, the species typically lived along brooks and rivers. It settled there dependent on the flood dynamic of temporary and continuously shifting small bodies of water. In its replacement habitats in human civilization, it is still dependent on temporary small bodies of water on loamy ground, such as tractor trails, puddles, and small ditches. Mostly, these areas are bereft of vegetation and free of competing species and predators. Through the quick heating of small bodies of water, a rapid development of spawn and larvae is guaranteed. These pioneer species can be found mainly in quarries, clay and gravel pits, and on marching grounds.
The superior mobility of the young of the species allows spontaneous settlement of newly discovered living spaces. On land, the creatures look for hiding places under stones or dead wood and in the furrows and crevices of rocks. The yellow-bellied toad dwells in mountainous and hilly countries in middle and southern Europe. It is widely spread across the high hill area of middle and southern Germany and the Upper Rhine River Plains, but in few places.
Males begin to produce mating calls in the late spring and continue as late as August. As the species does not have a vocal bladder, in contrast to the red-bellied toad, its call is quite gentle.
