MTS4N 391 – Trading plastic 4 shells by Shawn Miller

Posted on November 8, 2021 by Admin11

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

Posted on October 19, 2021 by Admin11

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!

Meet Green Tea, A large Blueberry hermit crab found adapting with single-use plastic.

The hermit crab was offered an assortment of shells. Green tea made the switch into the donated seashell ” No More Plastic Caps ” MTS4N #383.

After I photograph the hermit crab within its new home, I release it back into the wild and keep the plastic cap. Happy crab – Happy Home!

In August I reached out to my friend Martin Bailey and asked him if he wanted to be part of the project: Trading plastic for shells. He agreed and I carved ” No more Plastic caps ” on an MTS4N shell for him.

Martin asked me if I would join him on his podcast to discuss the project. Trading plastic for shells. It was great catching up with him!

Gigantic Hermit Crabs Found On Okinawa

Posted on October 5, 2019 by Admin11

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.

Indonesian hermit crab (Coenbita brevimanus)

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.

I also found hermit crabs adapting with a variety of marine shells from the Philippines at the same location.

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

Maeda flats

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.

Iheya beach

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 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.

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.

Searching for the Ryukyu Ghost Crab by Shawn Miller

Posted on September 19, 2018 by Admin11

Ghost crabs are one of the fastest terrestrial crabs on the planet. They live in burrows underneath the sand on the coastline. They are found scavenging for food early in the morning and late in the evening to avoid predators. These sand crabs can change colors to adapt to their environment. In Okinawa, we have two species of Ghost crabs, the Horn-eyed crab (Ocypode ceratophthalmus) and the Smooth-eyed ghost crab (Ocypode cordimanus).

Ghost crabs have three ways to avoid predators.

Stay close to their burrow and retreat into it quickly.
Escape into the surf zone and burrow underneath the wet sand.
Stay still and slowly dig into the beach sand

These crabs have the ability to fold their eyes into grooves for protection.

These crabs were photographed on white for the Meet Your Neighbours Biodiversity Project. The project is dedicated to connecting people worldwide with the wildlife in their communities. All images are used for conservation awareness and educational purposes.

The Juveniles can be extremely colorful depending on their surrounding environment. I have been finding more and more trash washed on the shoreline. Could the crabs possibly be adapting to the colors of the sounding marine debris washed ashore?

the Smooth-eyed ghost crab ( Ocypode cordimanus)

All ghost crabs are scavengers, mainly feeding on seaweed, fruit, seeds, other crabs, turtle hatchlings, and insects.

These crabs are beautiful creatures and hopefully, you will get the opportunity to see one in the wild.

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.

Crabs With Beach Trash Homes – Okinawa, Japan

Posted on October 19, 2014 by Admin11

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.

Below are some of my favorite images photographed on a portable field studio board (MYN Technique). The crabs are safely placed on a white studio board, photographed and released back into the natural environment (MYN Technique).

It’s important to photograph the hermit crabs in their natural habitat. I prefer to photograph them using a wide angle lens to achieve a unique perspective.

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.

Otis Brunner found this hermit crab flattened on a beachside parking lot. As you can see the plastic doesn’t provide much protection.

Behind the scenes photograph ” Crabs with beach trash homes ” I have documented over sixty crabs with beach trash homes. If you would like to see more images check out my Flickr account.
