I found a MTS4N seashell on Okinawa. What should I do?

Featured

Posted on January 30, 2022 by Admin11

So far, I have placed over seven hundred marked turbo seashells in the coastal forest for hermit crabs in need. The shells are marked and numbered with the hashtag #mts4n ( Make The Switch For Nature ). Hopefully, labeling the surface of the seashells will prevent poachers, beachcombers, and anglers from taking them.

Hermit crabs are a national living monument species of Japan. Collecting them is against the law. Take photos only!

What to do if you find a #MTS4N or #MILLER shell:

Take a photograph of the Hermit crab in its natural habitat
Enjoy the moment and do not harass it
Share on social media and tag #mts4n
These occupied shells are not collectibles; do not take them

The Mission of the Make the Switch 4 Nature (MTS4N) Hermit Crab Conservation project is to spread joy, inspire change, and save lives

What to do if you find a hermit crab adapting with plastic

Take a photograph of the hermit crab in its original habitat
Leave the hermit crab alone and do not harass it
Send me a DM with the exact beach location
I will place empty shells in the coastal forest for the hermit crabs

Have you ever taken an empty seashell from the beach? I am guilty. Most people don’t realize that they are taking the potential home of a hermit crab.

Did you know that hermit crabs are not born with shells?
As hermit crabs grow, they depend on various empty shells as their homes. Hermit crabs do not make their own shells; instead, they use discarded shells from marine snails that wash ashore. They also adapt by using land snail shells found in the coastal forest. If you are a shell collector, please return all unwanted shells to the coastline. #taketrashnothomes

It’s crucial to protect these beautiful creatures for future generations. Hermit crabs play an essential role in the coastal ecosystem. Hermit crabs do not belong in cages; please leave them in their natural habitat.

2024 has been a busy year for hermit crab poaching. In April and May, we found many traps in the coastal forest. If you see any suspicious activity, please call the local police.

Hermit crabs do not belong in a cage. Let’s keep wild crabs wild.

Please help me make a difference by supporting the #MST4N Hermit Crab Conservation Project. Please check out my Patreon page, MakeTheSwitch4Nature. I will collect a bucket full of marine debris for every supporting member. Our waste is a massive problem on our beautiful shorelines.

Do you have any seashells collecting dust at home? If so, consider giving them back to nature. #taktrashnothomes

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.

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.

June 10th, 2010 was my first experience seeing a hermit crab with a trash home.

My series ” Crabs with beach trash homes ” has been featured on World Wildlife Fund, Petapixel, Business Insider, National Geographic, Atlas Obscura, Global citizen, Plethorist, Daily Telegraph, Little things, 15minutenews, Roaring earth, Hyperdojo, News.com.au, Follow news, Neotorama, BoingBoing, Insider, Activist, Now100fm and varies Scientific websites.
