Oriental Fire-Bellied Toad (Bombina orientalis)species of least concern





Classification: Introduced Species


The Oriental fire-bellied toad (Bombina orientalis) is a small semiaquatic frog species found in northeastern Asia, where they primarily dwell in slow-moving bodies of water and temperate forests. Quite common throughout much of their range, these frogs have mild toxins that can be excreted through their skin, with their vibrant underbellies serving as a warning of this. While not a true toad, their green and black skin is covered in small tubercles, giving them a toadlike appearance. Their sounds, mainly produced by males during the mating season, are very unlike those of other frogs.


Description: Oriental fire-bellied toads can be bright, grayish, or brownish green, with black mottling on their dorsal regions. Like other Bombina species, B. orientalis has a brightly colored ventral region, which can be yellow, red, or orange-red, mottled with dark spots. The finger and toe tips are usually red. The skin on its upper side is covered in small tubercles, the most pronounced of the genus Bombina. Although it is typically referred to as a toad, the fire-bellied toad is not a true toad. They can reach a length of about 1.5 to 2.0 inches, weighing about 0.99 to 2.01 oz. Males and females can be told apart by the males' nuptial pads on their first and second fingers.


Habitat: They are semiaquatic, generally dwelling in slow-moving streams or ponds. When out of the water, they can often be found in coniferous and broadleaved forests. They can be found at elevations of up to 3,600 ft. They are very resilient to environmental disturbance, especially compared to other amphibians, and as such can be found living and even breeding in heavily polluted water.

Diet: As larvae, Oriental fire-bellied toads consume algae, fungi, detritus, plants and protozoans. As adults, their diet consists of terrestrial invertebrates, including worms, molluscs and insects. Their diet in the wild contributes to their toxicity, and for that reason, wild specimens have more potent toxins. Oriental fire-bellied toads are incapable of extending their tongues to catch prey, but must instead leap at their target.


Reproduction: Breeding takes place around mid-May, when temperatures become warmer. It is at this time that the toads emerge from hibernation. Males call to the females with a light sound that is comparable to a musical triangle. They will jump onto the backs of any other fire-bellied toad that happens to pass by, which in some cases will cause them to accidentally attempt to mate with other species of amphibians, fish, plants, or even human fingers. Females lay 40 to 110 eggs in a large cluster near the surface of the water. The tadpoles begin to develop legs in 6–8 weeks, and are fully metamorphosed by August or September.


Status: The oriental fire-bellied toad was listed as least concern species by the International Union for Conservation of Nature with little threat of extinction, although the population is declining, but not at a significant rate. They occur in many protected areas in China and the Koreas, as well as six Russian nature reserves. The population in the Russian part of their range may be more threatened than others. Dangers include pollution, urbanization, and use in traditional Chinese medicine.
