Akamata – The Ryukyu odd-tooth snake

The Ryukyu odd-tooth snake  (Lycodon semicarinatus) 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 on the road than alive.

When threatened they pull back, stand high and prepare to strike!  They will bite when threatened.

The small snakes often feed on small lizards.  This beauty ate a common gecko tail first.

The Akamata is one of the few snakes that feed on sea turtle hatchlings in northern Okinawa.

This was my first 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 a common occurrence with other non-venomous snakes around the world. I believe this juvenile snake saw me as a threat.

People often ask me what is the purpose of conservation photography? Having the ability to affect some form of positive change in the environment and make a global difference with the photographs. Hopefully, the images will inspire people to care more about nature and make a positive difference in the environment.
