The Family Bombinatoridae consists of small to medium-sized frogs, commonly known as fire-bellied toads, found mainly in Europe and Asia. These amphibians are notable for their brightly colored ventral surfaces, which serve as a warning to predators of their toxicity. They are generally aquatic or semi-aquatic, inhabiting ponds, marshes, and slow-moving streams. Bombinatorids have flattened bodies, webbed feet for swimming, and a distinctive unken reflex—arching their brightly colored bellies upward when threatened. They primarily feed on insects and other small invertebrates and play an important role in controlling insect populations in their ecosystems.
