Thriving Upside Down by Shawn Miller

Posted on December 14, 2019 by Admin11

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

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

I Finally Found the Yanbaru Kuina

Posted on November 9, 2019 by Admin11

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.

The Common Moorhen (Gallinula chloropus) has a bright red head shield, yellow legs with distinctive white feathers underneath. The Common moorhen is found near marshes, local parks and small rivers. This bird is very common in Okinawa

Scientific name: Gallinula chloropus
Common Name: Common moorhen
Distribution: Okinawan wide
Habitat: City parks, rivers and creeks
Diet: Vegetation and small aquatic animals
Average Size: 30 to 37 cm

The Difference: The Yanbaru kuina ( Okinawa rail ) has an orange beak with bright orange legs. The underneath is black with white bars.

The Yanbaru kuina is a flightless bird found in northern Okinawa. It is a protected species and declared a living natural treasure. It is currently listed by the International Union for Conservation of Nature (IUCN) as an endangered species. In 2012 populations of this endemic bird were estimated at 1500 by the Environment Ministry. As of October 2016 populations have declined to 480 mature individuals according to IUCN assessment.

Scientific name: Hypotaenidia okinawae
Common Name: Okinawa Rail
Japanese Name: Yanbaru kuina
Distribution: Northern Okinawa
Habitat: Forests
Diet: Small insects, worms, snails and fruit.
Average Size: 31cm
Threats: Habitat loss, and the threat of mongoose and feral cats.

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.

Babylonia arealata (Coenobita purpureus)

hexaplex cichoreum (Coenobita cavipes)

Volema carinifera (Coenobita cavipes)

Melanella candida (Coenobita purpureus)

House Geckos of Okinawa

Posted on September 22, 2019 by Admin11

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 –

They have the ability to lay eggs on vertical walls
They have no eyelids
They can walk upside-down
When threatened they can release their tail
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!

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.

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.

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.

Searching for the Amami Oshima Frog by Shawn Miller

Posted on August 3, 2019 by Admin11

The Amami Oshima frog is featured in National Geographic this month for the series ” Wildlife As Canon Sees It “

The Amami Oshima Frog (Odorrana splendida) is considered the most beautiful frog found in Japan. It is only found on Amami Island and is listed as an endangered species. It is one of the many endemic species facing extinction due to habitat loss. This protected species is designated as a living national treasure of Okinawa.

Scientific name: Odorrana splendida
Distribution: Amami Island
Habitat: Forest streams
Diet: Insects, worms, and millipedes
Average Size: 90mm-110mm

We were on the Island for a short period of time but managed to see eight Amami Oshima frogs. It rained the entire time but that didn’t stop us, we were on the mission to find the endemic species. I explored the island with Zoologist Valdimir Dinets and bat Scientist Jason Preble. We were fortunate to see the Amami rabbit, Amami Jay, Owston’s woodpecker, Hime habu, Ryukyu robin, Amami woodcock, Amami Spiny rat, Otton frog, Amami tip-nosed frog, Whip scorpion, Wood pigeon, Coral snake, Crocodile newt and the banded ground gecko endemic to Tokunoshima. Below are some of my favorite images of the Amami Oshima frog in it’s natural habitat.

We also found a small pond with Amami Oshima tadpoles.

Please pay attention wildlife crossing the roads at night.

Bottle Cap Challenge – No Kicking Just Picking!

Posted on July 6, 2019 by Admin11

The bottle cap challenge is a viral trend started by martial artist Farabi Davletchin. He was the first person to perform a precision spin kick and twist off the cap of the bottle using his foot. In 2017, I started a my own bottle cap challenge. The goal was to see how many twist top caps I could collect in fifteen minutes. Its an exciting challenge and I recommend getting others involved. Make it a friendly competition and document your beach trash finds using the Clean Swell app by Ocean Conservancy.

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

Next time your at the beach, take a minute and look around at the amout of single use waste on the beach. How do you feel when you see this waste?

Majority of the plastic bottles/caps that wash ashore become brittle and break down into smaller pieces. The smaller pieces (micro plastics) are harder to find and clean up.

Eventually these smaller pieces make it back into the ocean affecting the wildlife. Marine birds often mistaken and eat this plastic because it looks and smells like their natural diet (ex: fish eggs, crabs and small fish).

Even the marine fish will sometimes eat the plastic, they are attracted by the smell as well.

Hermit crabs are one of the few animals that can successfully adapt with our waste. They eventually move into this valuable real estate (plastic caps) and use it as a protective mobile home until they find a better option. Below are photographs of hermit crabs found naturally adapting with plastic twist caps.

This popular hermit crab was featured in honor of World Oceans Day 2019 on Stella McCartney’s website. Thank you all for bringing awareness to the plastic pollution problem.

Cryptic fish, Comets and Stars by Shawn Miller

Posted on July 1, 2019 by Admin11

The Comet (Calloplesiops altivelis) is a type of marine betta found in the beautiful waters of Okinawa. They hide in caves during the day. At night they come out to feed on small crustaceans. They are a mysterious fish and can be challenging to photograph. Comets are uncommon, yet very little is know about the behavior of these cryptic animals.

Scientific name: Calloplesiops altivelis
Common Name: Comet (Marine betta)
Distribution: Ryukyu Islands
Habitat: submarine caves
Diet: crustaceans and fish
Average Size: 20cm

Look close, can see the resemblance between the comet and the spotted moray eel?

When threatened the comet will stick its head into a hole and expose its tail end, which mimics the head of the a dangerous moray eel. The caudal fin also has detailed white lines that resemble the razor sharp teeth.

Having trouble getting close to marine life during your night dives? I recommend using the Light & Motion Sola 1200 red light feature. This feature enables the user to photograph marine life during the night without disturbing them. Most marine animals do not see the color red or react less to the red light.

Frogs of Okinawa by Shawn Miller

Posted on June 23, 2019 by Admin11

Individuals that study amphibians are know as herpetologists. The act of searching for these beautiful animals is known as herping. Okinawa has twelve species of frogs. They all have the ability to live in the water and on the land. Most are nocturnal and feed on insects during the night. They are found in local parks, forests, streams, puddles, and on the road at times.

If you would like to learn more about a specific frog, I attached a link above each photograph. Links in red are endangered species.
