Fire bellied frog

They are brightly colored, diurnal, and hardy; a combination that is hard to beat. Most are grass green with a bright red or orange ventral side. Their entire body is covered in black spots and blotches, which become thicker on their red belly, and often form a reticulated pattern. The dorsal side of some toads in captivity turns dark black or brown instead of green. Some have speculated that this is caused by a change in diet, light levels, stress, temperature, humidity, or a combination of those factors. Fire-bellied toads mature to a size around 2 inches (5 cm). Males can be distinguished by their more streamlined appearance and vocal ability. The ventral side of fire-bellied toads is red to indicate that they are poisonous.
