Japanese striped snake


Elaphe quadrivirgata, commonly known as the Japanese four-lined ratsnake or the Japanese striped snake, is a species of non-venomous colubrid snake native to Japan.

Geographic range

It is found in all areas of Japan apart from the Ryukyu Islands.

Description

It typically grows to a length of 1-1.5 m. The snake has a yellow or light brown ground color, and gets its scientific and common names from the four black lengthwise stripes sported by most individuals of the species. All-black variants exist; these are known in Japan as karasu-hebi.
Juveniles are reddish, and instead of lengthwise stripes have crosswise stripes and a spotted pattern similar to some venomous snakes.
The dorsal scales, which are weakly keeled in adults but may be smooth in juveniles, are arranged in 19 rows. The ventrals, which are angulate laterally, number 193-210. The anal scale is usually divided, and the subcaudals, which are also divided, number 70-96.

Behavior

Elaphe quadrivirgata is an active, diurnal snake.

Diet

It feeds on a variety of prey items, including frogs, lizards, insects, rodents, as well as birds and their eggs.
