Key identifying features
The Japanese Coral Snake is a small, secretive elapid found on the Ryukyu Islands of southern Japan. It shows a slender, smoothly cylindrical body, a small head barely wider than the neck, and a short tail, consistent with its mostly fossorial and nocturnal habits.
Coloration & pattern
The body is typically reddish-brown, orange, or coral in tone, often relatively uniform along its length, sometimes with faint darker speckling. Some individuals show a subtly darker vertebral line. The head often has a darker cap that can extend slightly onto the neck, providing useful contrast against the paler body. The venter is pale and largely unpatterned.
Head, eyes & scales
The head is small and rounded, not clearly distinct from the neck, with small eyes and round pupils. Scales are smooth and glossy throughout, a common trait among burrowing and semi-fossorial elapids that aids movement through soil, leaf litter, and rock crevices.
Size & body shape
This is a small snake, generally reaching 30 to 50 centimeters, with a slender, evenly cylindrical body and a short tail.
Range & habitat where you'll see it
The Japanese Coral Snake inhabits forested hillsides, rocky slopes, and areas with loose soil or leaf litter across the Ryukyu Islands of southern Japan. It is secretive and largely nocturnal, often found under rocks, logs, or leaf litter during the day.
How to tell it apart from look-alikes
Its uniformly reddish body combined with a darker head cap helps separate it from other small snakes in its range that may show more strongly patterned or ringed bodies. Its smooth glossy scales and small, rounded head distinguish it from rough-scaled colubrids, and it lacks the hooding behavior seen in larger elapids.
