The Ryukyu odd-tooth snake (Dinodon semicarinatum) is a non-venomous snake found throughout the Ryukyu Islands. They are fairly common here on Okinawa and are usually found at night. The Akamata is a natural enemy of the venomous Habu snake. They are one of the few snakes capable of feeding on venomous pit vipers. More effort should be focused on conserving this native snake for this specific reason. This beautiful snake has been overlooked and needs to be protected. Sadly I see more dead in the road than alive.

This My fist time seeing a juvenile Akamata pull back and puff out its head to resemble the diamond shape of a venomous pit viper. Is the Coincidence or mimicry. I know this is common occurrence with other non-venomous snakes around the world. I believe this juvenile snake saw me as a threat.
Have a great day!
