Ryukyu black-breasted leaf turtle, Yanbaru forest

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
  • Habitat:  Leaf littered wetland forests 
  • Diet:  Worms, snails, insects, crustaceans, and fruit
  • Average Size:  140mm- 160mm

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.

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.

Crabs With Beach Trash Homes – Okinawa, Japan

  Crabs with beach trash homes is a series I am currently working on. I photograph Blueberry hermit crabs (Coenobita purpureus) that have begun to use beach trash as their home. The crabs are photographed in their natural environment and also on white for the Meet Your Neighbours global biodiversity project. The images are used for environmental awareness and educational purposes.

 Blueberry hermit crabs are commonly found on local beaches in Okinawa. Most crabs are blue but occasionally have color variations of purple, pink, orange and or gray. They prefer to have a seashell as a protective home but when no shell is available they adapt.

Before plastic caps filled our shorelines, hermit crabs adapted using tree nuts if no shells were available.

It’s becoming more common to find crabs with beach trash homes.  I have friends combing local beaches in search of more crabs for my series. While these are cute images, our trash is becoming a serious problem to the ocean and the animals that call the shoreline home. I often find hermit crabs using a variety of plastic caps from twist top pet bottles, laundry detergent containers, small propane tanks, sports water bottles and beauty supplies.

Possible reason why Blueberry crabs adapt with beach trash
  • Limited number of available shells causing them to make due with the best homes they can find. This is a good example of adaptive behavior.

Hermit crabs are very social animals and often fight over shells. Having a protective lightweight shell that covers the abdomen (soft parts of the animal) is crucial for survival.

Hermit crabs are scavengers and take advantage of any food washed ashore. They mainly feed on dead fish, barnacles, other crabs, algae, insects, plants, fruit and various seeds. The screw pine (Pandanus odifer) is one of their favorite foods. I imagine long ago these vital plants lined our shorelines in abundance. Numbers are decreasing due to deforestation.

Eventually the fruit drops to the ground and the sweet smell attracts the hermit crabs

The hermit crabs feed on the the fresh keys and help with seed dispersal. They both benefit in this relationship.  The Pandanus tree provides shelter, shade, food for the hermit crabs.

Eventually the keys dry, turn brown and litter the local beaches. The dispersed keys provide a perfect environment for hermit crabs to blend in with.

Hermit crabs prefer to be in a shell that protects the entire body from predators. Sometimes they have to temporarily adapt with a much smaller shell.  The retracted hermit crab tightens up to protect itself.  Ball up, play dead and blend into the environment, minimizing the risk of being preyed upon.

Could this be a form of masquerading or just coincidence ?  It resembles (mimics) the shape of the screw pine seed to possibly avoid detection from potential predators.

I also photograph the hermit crabs using a dedicated macro lens. I mainly use the Canon 60 mm or 100 mm macro lens to concentrate on the subject. These crabs are fairly small and  it’s important to have a lens that will focus close and deliver high quality sharpness.

School project  ” Crabs with beach trash homes ”  My family and I collected trash on a  local beach in Onna village. This is just a small portion of our beach trash findings.  The kids did a great job creating a project with impact.

Canon EF 400mm f/5.6L USM Lens – Birds Of Okinawa

The Canon Ef 400mm f/5.6 USM lens is a light weight high performance prime lens. The auto focus system is impressively fast without hesitation. It performs best when photographing birds in flight and animals on the move. This is a very sharp high quality lens and would recommend purchasing it if you are on a limited budget.

The Common kingfisher (Alcedo atthis) is one of my favorite birds to photograph with the the Canon EF 400mm f/5.6L USM Lens.

Marine Life Washed Ashore – Typhoon Vongfong

Super Typhoon Vongfong was considered to be to be the strongest storm of the year. We were very lucky the strength of the storm died down before it landed on the Island of Okinawa. The typhoon brought heavy winds and rough sea conditions. A fair amount of marine life could not cope with these harsh conditions.

Using the Light & Motion Sola red light feature to document the marine life of Okinawa

I have been using the Light & Motion Sola series underwater lights for over two years now. They are the most reliable lights I have ever used underwater. The Sola photo series 800 and 1200 offer a red light feature. This feature enables the user to photograph the marine life without disturbing them. Most marine animals do not see or react to the red light.

I decided to put the Sola red light to the test on some marine subjects. I first setup a small studio saltwater aquarium to place the specimens in.

Aquarium setup – Meet Your Neighbours Project

I wanted to photograph some marine gastropods with their shell and body showing. I first tried using white light, but they immediately retreated back into their shell.  As soon as I turned on the red light the marine snails crawled around as if it was nighttime. This red light feature allowed me to get the documentation photograph that I planned.

Cowrie shells are one of many beautiful marine animals found in Okinawa. Photographing the animals on white isolate the subject without any distractions.

Light & Motion – The ultimate flashlight for wildlife photographers.

I have been using the Light & Motion Sola underwater lights for over two years now. I take them on all my adventures to include scuba diving, river trekking, caving and nature photography trips. These lights provide constant beautiful lighting and are extremely reliable, which is why they are the perfect light for me.

I recently purchased the Light & Motion Sola compact tray with the extension kit and one GoBe 700 wide light. I have been using this setup with the Canon 70D to document the wildlife in Okinawa. The flexible Loc-line arms are an awesome advantage. They are easy to move while having full control over the constant lighting.

The Light & Motion Sola 600 has a built in feature most people do not take advantage of. The light has a red light function which allows the user to get close to land and marine subjects without disturbing them. This red light is very effective and I highly recommend using it.

Underwater Macro Photography with an Ikelite housing

I have always enjoyed shooting macro photography ever since I purchased my first camera. Underwater Macro photography is challenging due to currents, buoyancy control and back-scatter in the water. Below are a few underwater images photographed using the Canon 70D with a Canon EF 100 mm f/2.8 USM macro lens. The Camera and lens are enclosed in an Ikelite underwater housing. I am currently using one Ikelite DS-160 strobe along with one Ikelite DS-200 underwater.
