MTS4N 391 – Trading plastic 4 shells by Shawn Miller

Meet Jet Black, A blueberry hermit crab found adapting with a discarded plastic twist top cap.

The hermit crab was offered an assortment of shells. Jet Black made the switch into the donated seashell ” MTS4N 391 LIZA N MAGS OCEANBNB ”

I photographed the shy hermit crab in its new home, then released it back into the wild. Happy Crab – Happy Home!


I now keep all the twist-top caps that were used by hermit crabs. I currently have 107 caps that have been traded for shells ( #MTS4N Trading Plastic 4 Shells Collection )

As you can see our trash is a serious problem on our shorelines. Some organizations are doing great things making a difference but it’s not enough, We must all work together worldwide and 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 4 nature.

It Will Get Better Mts4n #412 – Trading plastic 4 Shells

Meet Mustard, A blueberry hermit crab found adapting with a discarded marker cap.

A friend called to inform me she found a hermit crab ( mustard ) adapting with plastic. I grabbed some empty shells, the #mts4n bucket and drove down to a local beach in Yomitan village. We placed Mustard into the bucket and within fifteen minutes he made the switch.

Mustard made the switch into donated shell ” MTS4N #412 It will get better ” which is part of the positive carving series.

I photographed the hermit crab in its new home, then released it back into the wild. Happy Crab-Happy Home!

Good Luck Charms on Okinawa – The Chiragra Spider Conch

Conch shells are locally collected for food on Okinawa. The shells are used for shell craft and jewelry. The Chiragra spider conch (Harpago chiragra) is considered a good luck charm. It is known to bring good fortune, worn of evil spirits, and provide protection against fire. The Okinawans place the Chiragra spider conch on the outside of houses and buildings.

Below are some of my favorite conch shells found in Okinawa.

The beautiful conch shells are commonly confused with the hazardous cone shells. The main difference is that conch shells have a stromboid notch. A small side slit or indentation which allows the animal to see while moving.  The conch shells movement is much different as well, they travel using a jumping style movement instead of a steady crawling motion.

My daughter and I found this mutated strawberry conch shell in 2018. This is the first four-eyed conch shell I have seen. They naturally have two eyes, not four.

Mangrove Forests of Okinawa

Mangrove forests are one of the most threatened ecosystems on the planet. The beautiful forests support a huge diversity of species that humans depend on for survival.

Benefits of Mangrove forests 

  • Provide nursery areas for small fish
  • Provide coastal protection from storms
  • Clean toxins out of the fresh water
  • Reduce carbon dioxide
Mangroves of Senaga Island

Coastal development, rising sea levels, and pollution are the mangrove’s biggest threat. The roots act as nets catching plastic bags, fishing ropes and other marine debris.

Mangrove pollution

Over time the toxic plastic smothers the trees.

Mangrove pollution
Mangrove Pollution

Mangrove roots protect small fish, crustaceans, and sea birds from predators.

My two favorite crustaceans of the mangrove mud plats are the Okinawa mud lobster (Thalassina anomala) and the Ryukyu soldier crab (Mictyris guinotae).

Mangroves trees can survive in freshwater and saltwater. They are a valuable ecosystem and must be protected.

Our waste is having a massive impact on the coastal forests of the Ryukyu Islands. This post is not to make people feel guilty or lose hope. It is to inspire people to change. Make The Switch 4 Nature!

Thriving Upside Down by Shawn Miller

Randall’s assessor (Assessor randalli) is a rare fish found living in submarine caves. They are usually seen hovering upside down in small groups. The male guards the eggs by keeping them in his mouth until they hatch (mouthbrooders). A challenging fish to find and photograph. These exotic species are sought after by fish collectors.

* This species is named after Ichthyologist John Ernest Randall. 

  • Scientific name: Assessor randalli
  • Common name: Randall’s assessor or Randall’s devilfish
  • Distribution:  Japan-Taiwan
  • Habitat:  Submarine caves
  • Diet: Crabs, shrimp, and fish
  • Average size: 25-40mm
  • Color: Dark blue

Can you see the assessor’s hovering upside down?

DSC_8112

 Why do these fish live upside down?

  • A way to confuse predators
  • Evasive stratedy, making it easier to back into crevises
  • An adaption made for presision swimming among the submarine caves

I Finally Found the Yanbaru Kuina

When I tell people I am a nature photographer, they often ask me if I have ever seen a Yanbaru kuina. Friends are always so excited to tell me that they found a Yanbaru kuina in central Okinawa. I feel bad telling them the bad news. More than likely, they found a common moorhen. The common moorhen is often mistaken for the Yanbaru kuina.

Gigantic Hermit Crabs Found On Okinawa

Last year, a friend and I stumbled upon a local beach with gigantic hermit crabs. All of the hermit crabs were found adapting with non-native seashells.

Where did these shells come from?  The shell shack

The shell shack is an old wooden shed filled with boxes of imported craft shells from the Philippines. The hermit crabs found an opening and took advantage of this real estate.

Polished muffin (Ryssota ovum)

The most abundant shell was the polished muffin (Ryssota ovum) land snail. This shell is native to the Philippines and is twice the size of any land snail on Okinawa. The muffin shell is a perfect mobile home for the land hermit crabs. It’s lightweight, durable and large.

The hermit crabs were healthy and doing well. I didn’t see any hermit crabs adapting with plastic or any twist top caps.

House Geckos of Okinawa

The house gecko is the most abundant reptile on Okinawa. They can be found in apartments, buildings, public restrooms, outdoor phone booths, and vending machines. In many countries, they are considered good luck in the home.

  • Scientific name: Hemidactylus frenatus
  • Japanese name: Yamori
  • Distribution:  Ryukyu Islands
  • Habitat:  Forests, apartments, and public restrooms
  • Diet: Insects and small spiders
  • Average Size:  50mm-67mm

Interesting facts about house geckos

  1. They have the ability to lay eggs on vertical walls
  2. They have no eyelids
  3. They can walk upside-down
  4. When threatened they can release their tail
  5. They communicate by making loud chirping sounds

House geckos have amazing night vision.

Their tongues are used for grooming, catching food, and searching for a mate.

They have specialized walking pads with tiny hairs called setae. These hairs allow them to stick to surfaces and even walk up vertical walls.

Geckos are often found around artificial light sources (vending machines). The lights attract insects during the night. A buffet for the geckos!

Shawn Miller

Geckos and other wildlife are found in public restrooms. The light source attracts a variety of insects. Always check the scene before you sit down, you never know what’s hiding behind the toilet.

During the day, geckos seek shelter in warm areas. House geckos are responsible for high repair costs on air conditioning units. They crawl on the AC circuit board and cause it to short circuit. Repair costs are very expensive.

short circuit

House geckos usually lay only two eggs. This is a good example of a communal nesting site. These eggs were laid on a vertical concrete wall.

Geckos are often found crossing public roads during the night.  Please pay attention to crossing wildlife. The ants took advantage of the roadkill.

Roadkill Okinawa

I often find geckos on local beaches near the coastal forest. Juvenile Ryukyu odd-toothed snakes (Akamata) prefer to feed on these sand-dwelling geckos.

Even the geckos have to adapt with our waste. I found this gecko under a piece of marine debris washed ashore in northern Okinawa.
