Some small frogs have bright bellies. 

When they feel scared, they arch their backs. This shows their bright bellies to others. Most of their skin is green or brown.
These toads live in Europe and Asia. They like to stay near still water. They like ponds and small pools.
Male toads make a loud sound. It sounds like a dog's bark. They are often active at night.
Fire-bellied toads are small frogs. They live in Europe and Asia. Most of their skin is green or dark brown. But their bellies are bright red, yellow, or black. 

When a toad is scared, it does a special move. This is called an unkenreflex. The toad arches its back. It raises its legs to show its bright belly. 
These toads like to stay near still water. They live in ponds, pools, or slow rivers. Some live high in the mountains. 
Female toads lay many eggs. They hang the eggs on plant stems. The babies grow in water. Tadpoles eat algae and plants. As they grow, they eat insects like flies and beetles. Male toads make a loud mating call. It sounds like a dog's bark instead of a croak.
Fire-bellied toads are a special group of small frogs. They belong to a genus called Bombina. These frogs are famous for their bright bellies. Their undersides show red or yellow patterns mixed with black. This is called aposematic coloration. This bright color acts as a warning to predators. It tells hunters that the toad has a foul taste. Most of their other skin is green or dark brown. 
These toads have a clever way to stay safe. When they feel threatened, they perform the unkenreflex. This name comes from the German word for fire-bellied toad. During this move, the toad arches its back up. It raises its front and back legs high. This action shows off the bright colors on its belly. The bright colors warn the predator to stay away. 
There are six different species of these toads. Some live in mainland Europe, like the European fire-bellied toad. Others live in parts of Asia. You can find them in China, Korea, and Russia. The Hubei firebelly toad lives in China. The Yunnan firebelly toad lives in Yunnan and Myanmar. The Apennine yellow-bellied toad lives in Italy. The Oriental fire-bellied toad lives in Korea and Russia. 
These toads live in many different places. They like habitats with stagnant water. This means they prefer still water like ponds or puddles. They also like calm backwaters of rivers or floodplains. Some species live at high altitudes. Asian species can live over 3000 meters high. They can even live in small water-filled ruts. 
Life for a toad starts in the water. A female might lay between 80 and 300 eggs. She hangs these eggs on plant stems. The babies grow in pools or puddles. Tadpoles eat algae and plants to grow. Adult toads eat insects like flies and beetles. They also eat shrimp and worms. In a pet tank, they can live for many years. Some have even lived over 20 years. 
Fire-bellied toads are a unique group of small amphibians. They belong to the genus Bombina. Most species in this group are quite small. They are famous for their striking colors. Their undersides feature bright red or yellow patterns mixed with black. This specific type of coloring is called aposematic coloration. It serves as a visual warning to potential predators. The colors suggest that the toad has a foul taste. While their bellies are bright, their backs are usually green or dark brown. 
To defend themselves, these toads use a specific movement called the unkenreflex. The name comes from the German word "Unke," which means fire-bellied toad. When a toad feels threatened, it arches its back upward. It then raises its front and back legs. This posture exposes the brightly colored ventral region to the predator. By showing these colors, the toad communicates its unpalatability. This defensive mechanism helps the toad avoid being eaten. 
There are six recognized species within the Bombina genus. The European fire-bellied toad, Bombina bombina, lives in mainland Europe. The Oriental fire-bellied toad, Bombina orientalis, is found in Korea and Russia. In China, you can find the Hubei firebelly toad and the Yunnan firebelly toad. The Yunnan species may also live in Myanmar. The Apennine yellow-bellied toad, Bombina pachypus, lives in Italy. Finally, the yellow-bellied toad, Bombina variegata, lives in southern and middle Europe. 
These toads live in many different environments. They generally prefer a moderate or continental climate. Most species seek out stagnant water. This includes ponds, puddles, and calm backwaters of rivers. They are also found in floodplains and flood pools. Some species live at very high altitudes. The yellow-bellied species often live near mountain streams in small water bodies. Some Asian species can live at altitudes exceeding 3000 meters. 
The life cycle of a fire-bellied toad begins in the water. A female typically lays between 80 and 300 eggs. These eggs are often found hanging from plant stems. The offspring develop in pools or puddles. Tadpoles primarily eat algae and higher plants. Metamorphosis is a complete process that takes a few weeks. This process usually peaks during July and August. The resulting toadlets are about 12 to 15 mm long. In some cases, eggs laid in August only metamorphose after the winter. These specific toadlets reach 3 to 5 cm and have white bellies. Adults have a much broader diet. They eat insects like flies and beetles. They also consume shrimp, larvae, worms, and terrestrial arthropods.
Fire-bellied toads are also popular in captivity. Species like B. orientalis and B. bombina are common exotic pets. They can be kept in vivaria, which are specialized enclosures. In these settings, they are known to be robust and long-lived. Captive toads usually live between 3 and 10 years. However, some specimens have lived for over 20 years. They have a very ferocious appetite. Owners must monitor their food to prevent overeating. They can eat crickets, moths, minnows, and even pinkie mice. Males can sometimes act aggressively toward one another. 
Understanding their biology helps us see how they interact with the world. The toads secrete certain substances for defense. They produce bombesin and 5-hydroxytryptamine. These chemicals can cause irritation to the eyes and skin. Most cases of exposure involve young children. These instances usually do not cause major clinical effects. They can typically be treated by rinsing the area. Because they are easy to raise and handle in solitude, they are useful for scientific study. Their unique mating calls also set them apart. Instead of a long groan, the male sounds like a dog's bark. This behavior begins in May and continues through mid-August.
