Hazardous marine life of Okinawa by Shawn Miller

Okinawa offers some of the best snorkeling and scuba-diving in the world. The ocean is filled with vast amounts of marine life only found here. With all recreational hobbies, there are hazards to be concerned with. Okinawa has much hazardous marine life, most of which is located in very shallow water.

Ways to avoid injury

    • Be respectful and avoid harassing, touching, and feeding marine life.
    • Maintain good buoyancy control 
    • Recognize warning signs of aggression
    • Avoid wearing shiny jewelry
    • Wear exposure protection 

The Lionfish is beautiful but a hazardous fish. The spines deliver a painful sting with potent venom injected into the body. The Lionfish is native to this region, so there is no need to try to kill it.

  • First aid: Wash the area with soap and fresh water. Remove foreign material and control any bleeding. Soak the limb in hot water (113 F / 45 C) or use hot packs. Seek immediate medical treatment.

Most sea urchin injuries are due to people accidentally stepping on them in the shallow surf. Wearing proper footwear decreases your chances of getting injured. 

  • First aid: Remove visible spines. Wash with soap and water. Pain control if needed-hot water  (113 F / 45 C) or use hot packs. Seek medical treatment if spines have entered the joints.

Moray eels deliver a vicious bite with razor-sharp teeth. In some cases, the eels latch on and do not let go. Avoid placing hands into holes and feeding the eels.

  • First aid: Control the bleeding and seek medical treatment. Monitor for signs of infection

The crown of thorn starfish has sharply pointed spines that deliver a painful sting. The spines inject venom, which causes extreme pain, discomfort, and possible nausea.  Most injuries occur because divers are cutting up the starfish with a dive knife and a spine accidentally penetrates the hand. The starfish has a purpose in the ecosystem, so leave it alone.

  • First aid: Remove visible spines. Wash with soap and water. Pain control if needed-hot water  (113 F / 45 C) or use hot packs. Seek medical treatment if spines have entered the joints.

The titan triggerfish is the most aggressive fish I have encountered. It is territorial and will guard its nest aggressively. Attacks can be severe, leaving wounds requiring stitches.  On several occasions, I pointed a dive light in their direction, and it scared them off. They do not like the directional light for some reason.

  • First aid: Control the bleeding and seek medical treatment. Monitor for signs of infection

Slow Down! – Let’s Protect The Okinawa Rail

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.

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.

Okinawa rail awareness signs are posted

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.

Posted speed limit is 40km/h © Shawn Miller

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.

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.

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.

The Light & Motion Nightsea Sola light can also be used on land. I am always searching for animals that fluoresce in the Yanbaru forest in northern Okinawa. You never know what you will find!

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

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.

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.

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.

Facing extinction – Ishikawa’s Frog (Odorrana ishikawae)

Ishikawa’s frog (Odorrana ishikawae) is the most beautiful frog found in Japan. It is only found in northern Okinawa and currently on the endangered species list. It is one of the many endemic species facing extinction due to habitat loss. Ishikawa’s frog is a designated living national treasure of Okinawa.

  • Scientific name: Odorrana ishikawae
  • Distribution:  Northern Okinawa-Japan
  • Habitat:  Forest streams 
  • Diet:  Insects, worms, and millipedes
  • Average Size:  90mm -120mm

This is my favorite frog on Okinawa. I have only seen about a dozen in the last three years.

They are also masters of camouflage. The unique pattern helps them blend into the moss and leaves on the riverside.

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.

Diving and Jiving in Okinawa, Japan

Okinawa has some of the best diving in the world. The Ocean is filled with beautiful coral reefs and vast amounts of marine life only found here. The water is warm and the clarity is outstanding. If you ever get the chance to scuba dive in Okinawa, go for it and do not hesitate. Below are a few of my underwater photographs over the years. All the images were photographed on scuba in the beautiful waters of Okinawa-Japan.

This Lion-fish is one of the many venomous animals in the ocean.
