Open encyclopedia reference
The Japanese rat snake (Elaphe climacophora) is a medium-sized colubrid snake found throughout the Japanese archipelago (except the far South West) as well as on the Russian-administered Kunashir Island. In Japanese it is known as the aodaishō or "blue general". It is non-venomous and is hunted by eagles and tanukis.
The snakes brumate for three to four months, mate in spring and lay 7–20 eggs in early summer.
