Sword-Tailed Newt

The Sword-Tailed Newt is native only to Japan's Amami and Okinawa island groups, and it's the largest member of the Cynops genus, reaching up to 18cm in length. Its black back is marked with lichen-like pale blotches and a bright orange dorsal stripe, while its belly glows a deep reddish orange when flipped over. Calm and unhurried in its movements, it tends to settle into captivity without much fuss, alternating between hiding in cover and growing comfortable around its keeper. Because it hails from subtropical islands, it tolerates warmth better than its relatives, so summer temperature management is less of a worry. Hardy and forgiving, it's a newt that rewards attentive care and suits anyone keeping an amphibian for the first time.

2Largest of Its Genus
This is the largest species in the Cynops genus, with adults reaching 11 to 18cm. It has a sturdy, substantial build compared to its relatives.
