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
  • Habitat:  Forests, drainage ditches and housing areas
  • 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.

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.

It is one of the many endemic species facing extinction due to habitat loss. Ishikawa’s frog is a designated national monument of Okinawa.

They live around mountain streams in the Yanbaru forest. They hide in cracks and crevices in the rocks making it hard to photograph them at times.

They are also masters of of camouflage. The unique pattern helps them blend into the the moss and leaves on the riverside.
