Ryukyu Long tailed Giant Rat – Ryukyu Islands

Posted on January 21, 2017 by Admin11

The Ryukyu Long-Tailed Giant Rat (Diplothrix legata) is an endangered species found on Amami, Tokuno and Okinawa Island. This rare species is currently listed as endangered on the IUCN red list of threatened species. It’s biggest threats are deforestation, feral cats, dogs and the introduced mongoose. I often see it crossing the road during the night in the Yanbaru forest. Please pay attention to crossing wildlife and drive at a safe speed.

Feral cats are a huge problem in Northern Okinawa.

Please watch your speed while driving through the wildlife protected area in Northern Okinawa.

The Yanbaru forest is designated as a wildlife protection area by the Okinawan prefecture, It extends from Nago to Kunigami village.

People often ask me what is the purpose of conservation photography? Having the ability to affect some form of positive change in the environment and make a global difference with the photographs. Hopefully, the images will inspire people to care more about nature and make a positive difference in the environment.

Average Size: 100mm -125mm

The King- Holst’s frog

The Holst’s frog is the largest frog found on Okinawa. It hides in holes, crevices and small caves in the day.

Searching for food

This is a size comparison photograph taken with the iPhone 6s. This is a good size frog but they do get larger than this.

The juveniles have a dark brown patch on the top section of the body. They blend in very well with their habitat.

Ryukyu black-breasted leaf turtle, Yanbaru forest

Posted on November 10, 2014 by Admin11

The Ryukyu black-breasted leaf turtle (Geoemyda japonica) is an endangered species found in Northern Okinawa. This turtle is decreasing in numbers due to poaching, deforestation and roadkill. The turtle is highly valued in the pet trade market and needs to be protected. It has been designated as a National Natural Monument of Japan and is currently on the IUCN red species list as endangered.

Scientific name: Geoemyda japonica (Fan, 1931)
Distribution: Okinawajima

The endangered turtle was featured on the cover of science workbooks. These workbooks are used for the junior high public school system in Okinawa, Japan.

This leaf turtle was not painted red or yellow. I photographed it using specialized blue lights and filters. The shell fluoresced bright yellow and the algae grow fluoresced bright red.

Take a close look, yes those are tortoise ticks. Photographed August 9th, 2014. I have been finding more turtles infested with ticks.

I usually find the Ryukyu black-breasted leaf turtle crossing the road at night or early in the morning.

All the roads in northern Okinawa have specialized wildlife steps for the animals that get trapped in the drainage ditch. These steps allow the turtles and other animals to crawl out safely using the steps.

The truth is I have seen more of these turtles dead than alive. Watch your speed!

Slow Down! – Let’s Protect The Okinawa Rail

Posted on August 26, 2014 by Admin11

The Okinawa rail is a flightless bird found in northern Okinawa. It is a protected species and declared a living natural treasure. It is currently listed by the International Union for Conservation of Nature (IUCN) as an endangered species. In 2012 populations of this endemic bird were estimated at 1500 by the Environment Ministry. As of October 2016 populations have declined to 480 mature individuals according to IUCN assessment.

Scientific name: Hypotaenidia okinawae

Common Name: Okinawa Rail

Distribution: Northern Okinawa

Habitat: Forests

Diet: Small insects, worms, snails and fruit.

Average Size: 31cm

Threats: Habitat loss and the threat of Jungle crows and mongoose.

The rail is often found feeding on the side of the road. It feeds on worms, snails, and insects.

When defending its territory, the rail will become aggressive and flare its wings.

If you are lucky you can catch the Okinawa rail feeding on the fruit of the cherry tree.

They roost high above the ground to avoid predators like the habu snake.

In 2014 I stumbled upon Scientists handling an adult Okinawa rail in the wild.

Awareness signs are posted along the main roads in northern Okinawa for their protection. I think they should also include speed bumps in the designated crossing areas for the rails.

The speed limit is only 40km/h so watch your speed for the protection of the wildlife. The rails are often seen feeding on the side of the road.

I have observed these birds crossing the road on many occasions. They have no problems crossing when people are driving the speed limit. Speeding decreases your reaction time, slow down and pay attention to all crossing wildlife.

What to do if you find an injured rail.

People often ask me what is the purpose of conservation photography? Having the ability to affect some form of positive change in the environment and make a global difference with the photographs. Hopefully, the images will inspire people to care more about nature and make a positive difference in the environment.

Fluoro-diving in Okinawa, Japan -Underwater Fluorescence by Shawn Miller

Posted on June 29, 2014 by Admin11

The Light & Motion Sola NightSea blue light will enhance your night diving experience like nothing before. It Is an underwater blue light that allows you to see fluorescence. The NightSea blue LEDs cause proteins and minerals to fluoresce brightly underwater. If you want to photograph fluorescence you will need a yellow barrier filter over your camera lens. The barrier filter will block the reflected excitation of light and transmit the fluorescence to deliver a psychedelic experience.

Underwater fluorescence by Shawn Miller

Below is a photograph of my underwater rig. This is the setup I use to capture the underwater fluorescence in Okinawa. I am currently using one Light & Motion Sola Nightsea and one GoBe nightsea blue light.

Below is a photograph of the Light & Motion Sola NightSea Underwater blue light photographed in the studio. I wanted to capture the blue light rays coming out of the light. No previous photos displayed this and I had to do it.

Some cases the fluorescence is so strong it can be photographed during the day without any specialized lights or filters. This red heart coral was photographed at a depth of Seventy-five feet.

In 2017, Some of my fluorescence enhancement photographs were published in Blue Planet 11.

Most of the marine life will fluoresce a beautiful green. I photographed this sea anemone in a submarine cave at Maeda Point, Okinawa. (Nightdive)

Corals that fluoresce orange are much harder to find here in Okinawa. (Nightdive)

I decided to experiment using the nightsea and custom filters over my strobes to give it an original look. I call this technique fluoro blending.(Nightdive)

I had this eel in my aquarium for a long time and had no idea it fluoresced until I exposed it to the Sola NightSea light.

The NightSea also provides a beautiful background color to complement the marine subject. This technique is becoming very popular in Japan.(Nightdive)

Glowing hydroids were recently discovered in 2015 by marine researchers in the Red Sea. I photographed these fluorescing hydroids in Okinawa-Japan.
