Bombina variegata (Source)
The yellow-bellied toad (Bombina variegata) belongs to the order Anura, the archaeobatrachial family Bombinatoridae, and the genus of fire-bellied toads.
Morphology and physiology
Specimens range from 28–56 mm, typically weighing between 2.3 and 12 g.[1] 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. [2]
Variation
A study conducted by Bogdan Stugren and Stefan Vancea in 1968 on yellow-bellied toads in Romania and the USSR established eight different forms of B. variegata, expanding on the three forms previously posited by Michalowski in 1958.[3] Each of these forms represents a ratio of yellow to black markings on the underside of the toad, ranging from nearly completely yellow (Form 1) to nearly completely black (Form 8). Stugren and Vancea found that the undersides of B. variegata specimens from northern regions typically had greater coverage by black markings than those that were found in southern regions.
Life cycle
Eggs
B. variegata lays 73 eggs on average,[4] with clutch size ranging from 45 to more than 100 eggs. Individuals typically lay multiple clutches every summer, allowing a single female to produce as many as 300 eggs in a year. Eggs are 1.5-2mm large and coated in a jelly 5-8mm thick and semi-opaque, ranging in color from mud-like to light brown.[1] Tadpoles typically hatch within 4 days after eggs are laid.
Tadpoles
Tadpoles develop rapidly and can reach 55mm in length. They have a blunt tail and are typically grayish-brown or, in rare cases, transparent.[1] Tadpoles and eggs are vulnerable to predation from various small pond-dwelling creatures, such as leeches, fish, and some aquatic beetles.[5] A study published in 2016 in the Canadian Journal of Zoology indicated that tadpoles in warmer water develop more quickly than those in cooler climates, meant to mimic the differing environments found in forested areas and sunny quarries.[6]
Mating
Males begin to produce mating calls in the late spring and continue as late as August.[7] As the species does not have a vocal bladder, in contrast to the red-bellied toad, its call is quite gentle.

Mating calls
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.
