Cynops pyrrhogaster
A newt endemic to Japan, admired for the striking contrast between its dark-brown back and vivid red belly. Hardy, long-lived, and kept mainly in water, it is a great beginner amphibian. Wash hands after handling, as its skin is toxic.
The Japanese fire-bellied newt (Cynops pyrrhogaster) is a salamander endemic to Japan, found in still waters such as rice paddies, ponds, and slow streams across Honshu, Shikoku, and Kyushu. Its rough dark-brown back contrasts with a vivid red-to-orange belly marked with black blotches, warning coloration that advertises the tetrodotoxin in its skin. Small (8-13 cm) but remarkably long-lived, it can exceed 20 years in good care. It is kept mainly in water with a haul-out island at 18-26°C, and a tight lid is essential because it is an expert climber. Wash hands after handling, and never release captive animals into the wild, as regional populations are genetically distinct.
