Underside yellow with black to leaden spots. Yellow parts usually connected

on the back.

April to July/August.

Bright, musical "poop….poop….poop", separated by less than 1.5 sec.
Males lack an internal vocal sac, so they hardly inflate their throat
when calling, in contrast to Fire-bellied toad males. Unlike most other
anurans Yellow-bellied toads usually live in or near the water from spring
to autumn. Yellow-bellied toads are satisfied with very small waters for
spawning, often even with water-filled car tracks.
