Hermit Crabs Living In Glass Bottles By Shawn Miller

Posted on May 4, 2019 by Admin11

Trash, treasure and the beautiful beaches of Okinawa.

One of my favorite things to do on the weekends is to go beach walking. Over the years, I have seen a significant increase in the amount of marine debris washed ashore. The trash is from all over the world, but majority of it washes up from Korea, China and Japan

This post is not to make people sad, guilty or lose hope, It is to bring awareness to the ongoing trash problem in our oceans and on our shorelines.

Majority of the glass bottles that wash ashore will eventually break. The resourceful blueberry hermit crabs take full advantage of any broken bottles and twist top caps. They eventually move into this valuable real estate and use it as a protective mobile home until they find a better option.

Hermit Crabs prefer to live in a natural seashell. The most durable home on Okinawa is the silver mouth turban shell.

Due to a decline in the number of seashells, the hermit crabs have to adapt with our trash to survive. Below are photographs of hermit crabs found naturally adapting with metal twist caps and broken glass bottles.

The Eyes of the Underwater World by Shawn Miller

Posted on May 2, 2019 by Admin11

Okinawa offers some of the best Scuba-diving in the world. I really enjoy the art of underwater macro photography. Macro subjects can always be found, it just takes some imagination and good framing to create beautiful underwater abstracts. Animal eyes are challenging and exciting areas to focus on. Below are some of my favorite photographs of vision taken on the Island of Okinawa.

Amami Woodcock- The Birds of The Ryukyu Islands

Posted on April 29, 2019 by Admin11

The Amami woodcock (Scolopax mira) is considered a prefectural bird of Amami Island. They are a rare species mainly found on Amami and Tokuno islands. These ground dwelling birds are listed as vulnerable on the IUCN red list of threatened species.

Scientific name: Scolopax mira
Distribution: Amami, Tokuno and Northern Okinawa
Habitat: leaf littered forests
Diet: Beetles, crickets, moths, spiders, and worms
Average Size: 34cm – 36mm
Threats: Habitat loss and the introduced mongoose.

The Amami woodcock is a master of camouflage. It crouches down low and limits its movements in the leaf litter. When predators approach the woodcock will fly away in most cases.

In this case the female has chicks that she has to protect.

We managed to see one sub-adult, it quickly followed its mothers lead and fled the scene.

The mongoose is the biggest threat to the wildlife of the Ryukyu Islands. It was introduced to the Ryukyu Islands in the1900’s In order to reduce the venomous habu populations. All the islands are still battling this never ending problem.

All the photographs of the Amami woodcock were taken from the car through the back seat window. In the beginning, I had difficulty with the cameras auto-focus system. I adapted by mounting a Light&Motion GoBe light with a 500 search head to my tripod collar. This allowed the auto-focus system to be extremely responsive using the Canon EF100-400mm f/4.5-5.6L IS II USM.

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.

Earth Day 2019 Okinawa

Posted on April 21, 2019 by Admin11

Happy Earth Day 2019,

This post is not to make people sad, guilty or lose hope, It is to bring awareness to the ongoing trash problem in our oceans and on our shorelines.

As you can see our trash is a serious problem on our shorelines. Some organizations are doing great things making a difference but its not enough, We must all work together worldwide to attack this problem.

We all have the ability to make a difference by reducing the amount of single-use items we use daily. Change can be difficult but I challenge you to Make The Switch for Nature

Three items that can make a huge impact are:

Reusable thermos instead of single use
Reusable bag instead of a plastic bag
Metal utensils instead of single use plastic

I also recommend volunteering in a community beach cleanup at least once a year. Its important to see the amount of trash for yourself!

Hopefully this post will inspire you to make a positive change.

Ryukyuan Pygmy squids and hydroid-eating nudibranchs

Posted on April 14, 2019 by Admin11

In the summer of 2018, I documented some exciting animal behavior underwater. While searching for the blue-ringed octopus in a shallow reef cut, I stumbled upon the elusive pygmy squid (Idiosepius sp). I first photographed the Ryukyuan pygmy squid back in 2012 and was excited to see another one. This undescribed pygmy squid is only 10mm-14mm in size. It can be difficult to get an acceptable photograph of it free-swimming through the water.

Its amazing how fast squid can change color to blend into the sounding background. Look at that camouflage.

The pygmy squid has defined white nodules on the posterior end of the mantle used for attaching to seaweed and rocks.

I took a few photographs of the tiny squid and it eventually retreated into fireweed (Aglaophenia cupressina).

The fireweed looks like a harmless piece of seaweed but its actually a dangerous stinging hydroid. The fireweed delivers a painful sting causing redness, irritation and infection.

I returned to the exact location a few days later in search of the pygmy squid. I found the fireweed but it was much smaller, as if it was purposely cut down. These fireweed colonies have been in the same reef cut for over six years. What could have caused this devastation? Was it possible that a Scuba Instructor cut down the fireweed colonies for the safety of their students? I mention this because the hydroids are in a high-traffic swim-through area, and some days literally hundreds of divers swim through this reef cut.

My first thought was someone cut down the fireweed but I was wrong. It was actually a brightly colored nudibranch named Tenellia yamasui (Hamatani, 1993). The fireweed was infested with juvenile nudibranchs feeding on it.

You would think that the nudibranchs would be conservative and keep some food for the future. The sea slugs devoured the entire fireweed.

Ever wonder what this stinging hydroid can do to your skin? To learn more about the dangerous animals and treatments, check out my post on The Hazardous Marine Life of Okinawa.

Searching for Cephalopods by Shawn Miller

Posted on April 13, 2019 by Admin11

Lately, I have been getting out a lot more on night dives. The conditions have been great for Scuba diving and underwater macro photography. Diving at night is exciting because you never know what you will find. My last dive I stumbled upon a few new brightly colored nudibranchs and an undescribed pygmy cephalopod known as the pharaoh cuttlefish.

Could this pygmy cuttlefish be an undescribed species or just a clever juvenile broadband cuttlefish resembling the sand?

Scientific name: Sepia sp
Common Name: Pygmy or Pharaoh Cuttlefish
Found: Kin bay, Okinawa
Habitat: Sand bottom @ night
Depth: 35feet
Size: 17mm

More than likely this pygmy cuttlefish is Sepiella inermis. The pharaoh cuttlefish is absolutely stunning. I found this large specimen sand-dwelling during a night dive.

If you have never been night diving I highly encourage you to try it. If you want to learn more about Cephalopods of Okinawa, check out my post on the beautiful Blue-ringed octopus.

Cowrie Shell Eating Octopuses of Okinawa

Posted on March 25, 2019 by Admin11

In 2010, a friend sent me some beautiful cowrie shells from Hawaii. I noticed that a few specimens had tiny pin holes between the teeth on the underside of the cowrie shell. I asked him what caused this and he stated an octopus. So I decided to test this, I collected a small octopus and placed it in aquarium with no other marine life in the tank.

I placed only live cowrie shells in the tank to see if this octopus would eat the mollusks. I was completely surprised to find out that he was 100% correct.

The tiny drill holes are difficult to see without a magnifying glass.

Strangely, two of the cowrie shells had a drill hole on the top and another on the bottom side. The other eight specimens only had one drill hole on the bottom side. Is it possible that the octopus learned a new behavior? Did it it figure out the most efficient way after the two previous attempts?

All octopuses have a two-part beak used to immobilize and feed on their prey. The beak looks fragile but it one of the toughest and most durable substances made by marine animals.

Cephalopod Beak

My curiosity led me to the questions below Why does the octopus have to drill a hole when there is already a large aperture to feed from? Does the octopus use venom to paralyze the mollusk inside the shell after it drills the hole? If so, does the venom narcotize the mollusk which could allow the octopus to suck out the animal from the shell aperture like a shotgunning effect?

Have you ever wondered how the Okinawans catch small octopuses? Below is a colorful handmade lure made from cone shells and beads. I found it years ago at Awase flats.

Parasitic slugs of Okinawa

Posted on March 2, 2019 by Admin11

Gymnodoris nigricolor Is a tiny nudibranch that attaches to the fins of gobies. It is found in the winter months and then it seems to completely disappear when the water warms up. This nudibranch is by far the hardest to photograph because of its size and it stays attached to it’s host. When the goby feels threatened, it retreats into its burrow taking the tiny slug down the hole with it.

In order to photograph sand-dwelling gobies you will generally need a 50mm-100mm macro lens.

Be patience and move slowly. If your lucky the goby will accept your presence without retreating.

February 2018, I was fortunate to find Gymnodoris nigricolor crawling on the sand in search of a host

When the slug finds a host it will attach onto the closest fin.

Look close and you can see the buccal apparatus of the slug clamping down.

Once its locked down, the goby cannot shake the slug off.

No one really knows what happens next. Why does the nudibranch attach to the fins of its host？ Does this specialist feed on only the fins of gobies or is there another reason？

If you would like see stunning photographs of more sea slugs check out my post on nudibranchs

The Power of the Sunflower by Shawn Miller

Posted on February 4, 2019 by Admin11

Have you ever seen an unhappy person at a Sunflower festival?

Sunflower Festival, Kitanakagusuku Village

The Sunflower is a powerful plant that brings joy and happiness to all. Flowers are a source of Nature Therapy, sometimes just looking at them relieves stress and anxiety. Every year I visit these beautiful fields on Okinawa with friends and family. I strive to create a unique piece of art with my camera. Please enjoy some of my favorite photographs composed over the years.

The lonely hermit crab adapting with a lug-nut cover by Shawn Miller

Posted on December 22, 2018 by Admin11

This week I went out camping with some friends on Miyagi Island. While searching for fire wood I stumbled upon a blueberry hermit crab (Coenobita purpureus) adapting with a metal lug-nut cover. I have previously found many hermit crabs adapting with other man-made items such as pet bottle caps, glass bottles, light bulb ends, laundry detergent caps and various scoops. I was pretty excited about this and had to show off the interesting find to my friends.

The blueberry hermit crab is temporarily making due with the available lug-nut cover. It will eventually switch to a shell when it finds an appropriate size. If you would like to learn more about this adaptive behavior please check out my post on “Crabs with Beach trash homes”

* All Coenobita species on Okinawa are recognized as a living natural monument of Japan.

This slideshow requires JavaScript.

I also photographed the hermit crab on white for the Meet Your Neighbours Project. The technique eliminates distracting elements out of the background and shows the true beauty of the animal. The images are used for conservation awareness and educational purposes.

Later I offered lug nut a Turbo seashell and within five minutes he switched over to his new home.
