The eggs are laid in slow moving and still water sources. The eggs will develop into tadpoles and eventually transform into baby frogs.  I often find tadpoles thriving in farming water buckets.

If you see frogs, there is a possibility that snakes are near by. The snakes patiently wait for frogs in drainage ditches and still water sources. The Kajika frog is the Hime habu’s favorite meal.

They all have bright orange bellies, which serve as a warning sign to predators that they are poisonous. When threatened they produce a transparent skin toxin.

  •  Poisonous animals are toxic if you eat them or ingest their secretions.  Irritations may occur after handling these newts if you have open wounds. Avoid rubbing your eyes or placing your hands in your mouth.

The Sword- tailed newt is often found crossing the road on rainy days in northern Okinawa. The government has designed specialized wildlife steps for animals that get trapped in road side drainage ditches. These steps allow the newts to crawl out safely.

The Light & Motion Stella 2000 rocks part 1 – Okinawa, Japan

The Stella 2000 offers lightweight professional lighting for photographers and videographers. It delivers 2000 lumens of beautiful wide light on high power. It is waterproof to a depth of 100 meters and extremely durable.

Stella 2000 waterproof lighting

Stella 2000 waterproof lighting

My favorite features of the Stella 2000

  • Waterproof to 100 meters
  • Can be mounted on the camera hot-shoe, light stand,  loc-line arms or ball mounts.
  • Quick adjustable power output control
  • Fast charging and the ability to use the light when it’s charging

I tested the Stella 2000 in the humid jungle and on the shorelines of northern Okinawa. I used it as a spotting light, hiking light, camera modeling light and video light. I tested the light with the 120-beam angle with no modifiers, with custom made soft-boxes attached, studio umbrellas and with the combination of on-off camera flash.

I concentrated on the reptiles, amphibians and land crabs of northern Okinawa. Below are some of my favorite photographs.
