The Habu Hunters of Okinawa


The Taiwanese Habu was introduced to Okinawa in the 1970’s. They were imported for exhibitions and medical purposes. Somehow a few escaped and have populated the Island.  I have seen over a dozen on my night hikes in Onna village.

  • Scientific name: Protobothrops mucrosquamatus
  • Common name: Taiwanese habu or Brown spotted pit viper
  • Habitat: Rock walls, trees, and caves
  • Diet: Frogs, bats, mice, and birds
  • Average size: 80-150cm

The local government is actively trying to eliminate this invasive habu. Live traps are set up all around the Island. Do not open!

Last night, I saw a Taiwanese habu poking its head out of the sugar cane. There was a dead mouse three feet away on the road. I turned the car around and waited for a few minutes with my lights off. Eventually, a small Taiwanese habu slithered out of the field. I was hoping to see the habu eat the mouse. Instinct kicked in and the snake fled the scene. I returned in the morning, and the mouse was gone.

I often find them crossing the road or on sidewalks. It is wise to carry a flashlight on your night walks. The Taiwanese habu is aggressive and highly venomous. If you see one do not try and catch it.

Thriving Upside Down by Shawn Miller

Randall’s assessor (Assessor randalli) is a rare fish found living in submarine caves. They are usually seen hovering upside down in small groups. The male guards the eggs by keeping them in his mouth until they hatch (mouthbrooders). A challenging fish to find and photograph. These exotic species are sought after by fish collectors.

* This species is named after Ichthyologist John Ernest Randall. 

  • Scientific name: Assessor randalli
  • Common name: Randall’s assessor or Randall’s devilfish
  • Distribution:  Japan-Taiwan
  • Habitat:  Submarine caves
  • Diet: Crabs, shrimp, and fish
  • Average size: 25-40mm
  • Color: Dark blue

Can you see the assessor’s hovering upside down?

 Why do these fish live upside down?

  • A way to confuse predators
  • Evasive stratedy, making it easier to back into crevises
  • An adaption made for presision swimming among the submarine caves
