Akamata – Ryukyu odd-tooth snake

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 on the road than alive.

  • Scientific name:  Dinodon semicarinatum
  • Local name:  Akamata – Ryukyu odd-tooth snake
  • Distribution:  Ryukyu Islands

  • Diet:  Snakes, lizards, frogs, snakes, birds, baby sea turtles and rodents.
  • Average size:  100cm -180cm
  • Color:  Black, orange with a yellow belly.

They are often found crossing the road at night.

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

This 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.

The hunt for the habu – Izena Island

Izena Island is known for not having any venomous snakes on the Island. I always thought this was impossible since the surrounding islands all have venomous snakes. After five trips we finally found a Habu.

The Princess habu was found resting on a rock above a fresh water source.
