Yellow-bellied toads 

Small, charismatic amphibians best known for their bright yellow-and-black bellies—a warning signal to predators. They belong to the genus Bombina, a group often called fire-bellied toads.

They favor shallow, temporary water like:

Rain-filled puddles

Wheel ruts on dirt roads

Small forest pools

This makes them surprisingly adaptable—but also vulnerable to habitat disturbance.

Their underside is a classic example of Aposematism:

Bright yellow with black blotches = “don’t eat me”

Skin secretes mild toxins (not dangerous to humans, but irritating)

When threatened, they perform the iconic unken reflex:

Arch their back

Flip limbs upward

Flash that warning belly

It’s basically amphibian theater with a purpose.

Length: 1.5–2 inches (3.5–5 cm)

Back: dull gray/brown/olive for camouflage

Belly: vivid yellow with irregular black patches

Skin: slightly warty, not smooth like many frogs

They’re opportunistic little hunters:

Insects (flies, beetles, ants)

Small aquatic invertebrates

Worms

They feed both in water and on land edges.

Breed in warm months (spring–summer)

Lay eggs in small clusters in shallow water

Tadpoles develop quickly—important since their pools can dry up

Many populations of Bombina variegata are declining due to:

Habitat loss (especially disappearance of temporary pools)

Pollution

Road development

In some regions, they’re considered near threatened or protected.

They’re more aquatic than typical toads, often floating at the surface

Their pupils are heart-shaped or triangular (a neat ID feature)

They don’t hop much—they kind of crawl or paddle
