As of March 2018, The Pryers Keelback (Hebius pryeri) is considered a venomous snake found throughout the Ryukyu Islands. They are rear-fanged and require a strong long-term chewing style bite to inject the venom into the wound. They are a very common snake found on Okinawa. I often find them in the Yanbaru forest on my night dwellings.

This year (2018) the Okinawa government posted some education posters to bring awareness about the snakes of Okinawa. I was surprised to see the Pryers Keelback is now considered venomous.

The Pryers Keelback mainly feeds on the small frogs. Its favorite meal is the Kajika frog!

They generally feed on the animals head first.

Sometimes you will see them eat frogs feet first. This makes for a more interesting photograph.

I often find these snakes dead in the road. A large Yanbaru forest crab (Candidiopotamon okinawense) took advantage of the situation.
