Oriental Fire-bellied Toad

The Oriental fire-bellied toad is a 3.5–8 cm semiaquatic frog with a brownish-grey to green back and a vivid red-orange or yellow underside patterned with black. Its pupils are triangular and its upper skin strongly tuberculate. When threatened it arches to expose the warning-coloured belly, advertising toxic secretions. Females are larger; breeding males develop nuptial pads and thicker forearms (Animal Diversity Web).

Bombina orientalis inhabits Korea, northeastern China and adjacent Russia, using ponds, streams, swamps, springs, puddles and ditches. Adults ambush worms, molluscs and insects; larvae eat algae, fungi, plants and detritus. Females deposit clusters of 3–45 eggs repeatedly, producing 38–257 in total. Eggs hatch after 3–10 days and metamorphosis takes roughly five months. A soft repeated call is used during breeding (Animal Diversity Web).
