MTS4N 391 – Trading plastic 4 shells by Shawn Miller

Posted on by

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.

Millions of Pumice Stones Wash Ashore Okinawa’s Eastern Coastline

Posted on by

Due to an underwater volcanic eruption around the Ogasawara Islands, millions of pumice stones washed ashore on the eastern coast of Okinawa. Pumice stones are formed when lava and water mix together. The lightweight stones are abrasive and are mainly used to remove dead skin on the feet. ” take off your shoes and enjoy the walk “

The massive amount of fresh pumice in a confined area gave me a headache. It smelled a little like sulfur to me. The rotting barnacles attached to the stones didn’t help either.

The larger hermit crabs definitely had a hard time crawling over the pumice mounds washed ashore. I wonder how these stones will impact marine life?

The combination of earth, wind, and fire produced some beautiful natural abstracts.

The fresh pumice fluoresced under blue light. I used the Light & Motion Nightsea blue light to create this photograph.

Good Luck Charms on Okinawa – The Chiragra Spider Conch

Posted on by

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.

  • Euprotomus bulla
    Euprotomus bulla
  • Euprotomus aurisdianae
  • Euprotomus vomer
  • Lentigo pipus
  • Lentigo lentiginosus
  • Sinustrombus sinuatus
  • Lambis lambis
  • Thersistrombus thersites
Lambis scorpius - scorpion conch

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.

Thriving Upside Down by Shawn Miller

Posted on by

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?

 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

Posted on by

The Light & Motion Sola Photo 1200 is the most popular modeling light used for underwater macro photography. I have been using Sola lights for over seven years now. All Light & Motion lights are easy to use, lightweight, and reliable. My favorite feature of the Sola Photo 1200 is the red light option. This feature enables the user to photograph marine life without disturbing them. Some marine animals do not see red light.

The red light feature works great for photographing nudibranch’s, sea turtles, and cephalopods during night-dives. These animals are less affected by the red light.

The Paintpot Cuttlefish – Cephalopods in Okinawa

Posted on by
The Paintpot cuttlefish (Metasepia tulbergi) is one of the most beautiful marine animals in Okinawa. The skin of the paintpot cuttlefish is toxic (poisonous) if consumed. The paintpot cuttlefish contains a neurotoxin called tetrodotoxin (venom) used to paralyze its prey. Avoid handling or harassing this beautiful animal. If bitten, seek immediate medical treatment.
  • Scientific name: Metasepia tulbergi
  • Common name:  Paintpot cuttlefish or flamboyant
  • Distribution:  Ryukyu Islands
  • Habitat:  Sandy bottom and coral reefs
  • Diet: Crabs, shrimp, and fish
  • Average size: 50-80mm
  • Color: Golden-yellow with red coloration
DSC_4989 Cool facts about the Paintpot Cuttlefish  
  1. They have eight arms and two tentacles
  2. They are capable of producing a dark cloud of ink to escape from predators
  3. They have a parrot-like beak used for eating prey
  4. They use jet propulsion to move quickly through the water
  5. They can change their texture, pattern, color, and shape
  6. They use their arms to walk on the sand
  7. They are considered venomous and poisonous
When threatened, the paintpot cuttlefish produces vibrant colors to warn predators that they are toxic. The scientific term for this is aposematism. DSC_8214 They have a two-part parrot-like beak used for feeding. Cephalopod Beak Cephalopods can produce a cloud of ink to confuse and escape from predators when threatened. Cephalopod ink Below is a sequence of images, displaying their ability to change texture, shape, and color. They are masters of camouflage. An example of how well they blend into their environment. DSC_8207DSC_8208If detected or threatened, they will display colorful warning signs. DSC_8209DSC_8211

Every year, I look forward to finding the gigantic paintpot cuttlefish named Paintpot-Zilla. 20130617-DSC_0519-2
