The Holst’s frog ( Babina holsti ) is a rare species found in northern Okinawa. It is currently listed endangered on the IUCN red list. It is designated as a natural monument by the Okinawa Prefecture. This large amphibian is decreasing in numbers due to habitat loss.

Scientific name: Babina holsti (Boulenger, 1892)
Distribution: Northern Okinawa-Japan
Habitat: Forest streams
Diet: Insects, worms, snails and small reptiles
Average Size: 100mm -125mm

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

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.

Venomous snakes of Okinawa-Japan

Posted on April 3, 2016 by Admin11

Okinawa has three species of pit vipers and one coral snake. These venomous snakes are commonly found in the jungle. They are sometimes found in neighborhoods and local parks at nighttime during the summer season. Majority of the snake bites that I am familiar with happened on neighborhood night walks or harvesting sugar cane. I have seen pit vipers on public roads at night, on sidewalks, crawling on fences, on rock walls, in drainage ditches and inside vending machines.

The Okinawan Habu is the largest and most venomous pit viper found on Okinawa.

Scientific name: Protothrops flavoviridis
Common name: Okinawan or golden habu
Habitat: Rock walls, caves, tree lines, parks, farming fields and near fresh water
Diet: Mice, rats, shrews, bats, and birds
Average size: 100-200cm

Okinawa is famous for its Habu Sake. They say it helps with sexual dysfunction in men.

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 near Ryukyu Mura in Onna village.

Scientific name: Protothrops 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 Princess habu is the most common venomous snake on Okinawa. It is the smallest of the pit vipers found here.

Scientific name: Ovophis okinavensis
Common name: Princess habu or Hime habu

The Okinawan coral snake is extremely rare. I have only seen two specimens

- Scientific name: Sinomicrurus japonicus boettgeri

- Common name: Okinawan coral snake

- Habitat: Forest areas in northern Okinawa

Ways to avoid injury!

Avoid catching or handling venomous snakes
Wear exposure protection, such as snake boots when exploring the forest at night.
Bring a flashlight on night walks in the neighborhood

Nature Therapy – Photo Exhibition by Shawn Miller

Posted on January 18, 2016 by Admin11

The Exhibition will be held at the Okinawa Institute of Science and Technology (OIST) January 14th through February 29th. The free photo exhibition is open from 9:00 to 17:00 every day. The exhibition will feature forty inspiring images of underwater animals, crabs with beach trash homes and the endangered species of Okinawa. Photography By Shawn Miller. The wonderful people at OIST were kind enough to make this exhibition take place and produce beautiful advertisement posters.

Testing the Venus Laowa 60mm F2.8 macro lens underwater

Posted on July 20, 2015 by Admin11

Dive Team Miller Underwater set-up with Canon 70d Laowa 60mmn f2.8 macro lens- Ikelite housing with 8inch dome port, 1 ikelite 160 strobe , 1 ikelite 200 strobe, 1 sola 600 and 1 gobe 700 focus light.

The Venus Laowa 60mm macro lens is a technical lens with great optics. The specialized lens is manual focus and manual aperture selection. I had to use my wide angle dome port since this was the only port I had the lens would fit into. I preset the lens to a 1:2 ratio and used an aperture setting of F8. I went with the aperture setting of F8 since it was an overcast day and I wanted to see my subject through the viewfinder in the low light. I used two modeling lights to add artificial light, which allowed me to see through the viewfinder at a depth of 100 feet. The focusing distance was already preset on the surface, so all I had to do was to move the camera until I saw the subject was in focus and take the shot. It was very difficult to use with subjects that were moving. This was my first dive using this lens underwater and have more testing to do. Here are some of my images using the Venus Laowa 60mm macro lens underwater at Maeda point, Okinawa-Japan.

Test dive two, I set the aperture to F11 with a focus distance between 1:1-1:2. It was challenging working with all moving subjects. The dome port was to close for comfort for moving subjects such as fish. Stay tuned for more images later this week!

July 8th 2017, I took the Loawa 60mm out for another spin. This time I did not use underwater strobes. I set the Aperture on F5.6, shutter speed 1/200-1/640 sec and ISO settings 400-2500. I used the Light&Motion Sola 3800 and Sola 1200 to provide beautiful fill light.

Capturing fluorescence – Fluorescence enhancement photography by Shawn Miller

Featured

Posted on March 31, 2015 by Admin11

All photographers experience a time when their work becomes redundant and lose vision. The Light & Motion Sola Nightsea has opened up a new style of photography for me. Recently I have been blending the Light&Motion Nightsea blue light with ambient light underwater and getting beautiful vibrant results.

Some of my Fluorescence enhancement coral images were featured in The Blue Planet 11 publication. It’s always nice to see years of hard work finally pay off.

Light and Motion macro field setup – Constant lighting by Shawn Miller

Posted on March 30, 2015 by Admin11

Light and Motion lights produce constant lighting with studio quality output. This light configuration is convenient while shooting macro photography at night. The camera, tray, arms and lights are combined into one lightweight unit. The light output can be easily adjusted with a touch of a switch. Having the lights on loc-line arms allow simple light angle adjustments.

The custom Light and Motion macro field setup consists of

Sola Tray kit with extention tray and arms
Third custom loc-line arm mounted
GoBe 700 wide light
Sola 600 light
Sola 1200 light
Canon 70D with 60 mm macro lens and strap

I was fortunate to have beautiful weather both nights testing the constant lighting setup in northern Okinawa. Six of the animals below are endangered species listed as threatened on the IUCN red list. All of these night dwellers are decreasing in numbers due to deforestation.

Fluoro fingerprinting by Shawn Miller

Posted on February 21, 2015 by Admin11

On February 16th 2015, I went out reef walking at night during low tide. I brought my Light and Motion Nightsea blue light in search of marine life fluorescence. I stumbled upon an interesting find in the world of science. I call it Fluoro fingerprinting.

I flipped over a rock, a small sea cucumber fell off and began to fluoresce under blue light. I found another sea cucumber and photographed it using the blue light and yellow excitation filter but it did not fluoresce.

Holothuria (Platyperona) difficilis under blue light

I gently touched it with my finger and it fluoresced bright green, leaving the print of my finger on the surface of the sea cucumber.

Fluoro fingerprinting. Okinawa-Japan

I checked my finger and noticed it fluoresced light green under blue light.

Fluoro fingerprinting

I was excited about this find and posted it Flickr for some Identification help and explanation. Curt Fieldler emailed the photograph to Dr. Alexander Kerr from the University Of Guam Marine lab and he was kind enough to assist.

Dr. Kerr stated that the species is known to have green pigment that I have seen in other Sea cucumbers. As far as the fingerprint, It seems to indicate that touching the surface of the Sea cucumber exposes the underlying carotenoid, perhaps by mobilizing the the melanin pigments. So I think you have made an interesting find.

The next step was to photograph Holothuria (Platyperona) difficilis in a studio aquarium using the Meet your neighbours isolation technique. I wanted to show the animal stretched out displaying the tube feet and feathery feeding tentacles.

The last step was to photograph Holothuria (Platyperona) difficilis in its natural environment during the daytime.

Out of all the birds at the mudflats, the spoonbills are the most consistent hunters. They rest most of the day, but when its time to fish they always catch one fairly quickly.
