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.

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.

I often find these frogs hanging out on fences, concrete walls, farming buckets and other manmade structures. They usually stay up high to avoid the threat of snakes.

Sometimes habu snakes climb these fences in search of a meal. Majority of the time the snakes are unsuccessful.

Tree frogs have the ability to inflate into a defensive posture, making themselves appear too large to eat.

The Red-eared slider – Introduced animals of Okinawa by Shawn Miller

Posted on June 4, 2018 by Admin11

The Red-eared slider (Trachemys scripta elegans) is found throughout the Ryukyu Islands to include Mainland Japan. It was introduced in the 1950s by the pet trade market and is still sold in pet shops here in Okinawa.

Scientific name: Trachemys scripta elegans
Common name: Red-eared slider turtle
Distribution: Introduced to most of Japan and the Ryukyu Islands
Habitat: Ponds, drainage ditches, rice paddies and farm fields.
Diet: Insects, fish, frogs, snails, and plants
Average size: 20-28cm
Color: Brown and yellow with a bright red temporal blotch

Before you purchase one of these turtles make sure you are committed to taking care of it for a very long time. They can live for over thirty years. A big problem is people frequently abandon these aquatic turtles in local ponds and rivers. The introduced turtles compete with all native animals. Eventually, causing a negative impact on the environment.

I often find the Red-eared slider sunbaking on logs and rocks

These turtles are considered the most abandoned pet in the world. The local zoos often end up taking care of these abandoned reptiles.

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.

Pryers Keelback Snake – Reptiles of the Ryukyu Islands by Shawn Miller

Posted on March 11, 2018 by Admin11

As of March 2018, The Pryers Keelback (Hebius pryeri) is considered a venomous snake found throughout the Ryukyu Islands. They are rear-fanged and require a strong long-term chewing style bite to inject the venom into the wound. They are a very common snake found on Okinawa. I often find them in the Yanbaru forest on my night dwellings.

Scientific name: Hebius pryeri
Local name: The Pryers Keelback
Distribution: Ryukyu Islands
Habitat: Forests, grasslands, streams and rice fields
Diet: Frogs, frog eggs and small reptiles
Average size: 60cm-115cm
Color: Black & yellow with yellow bell

This year (2018) the Okinawa government posted some education posters to bring awareness about the snakes of Okinawa. I was surprised to see the Pryers Keelback is now considered venomous.

Look close at the split tongue flickering back.

The Pryers Keelback mainly feeds on the small frogs. Its favorite meal is the Kajika frog!

They generally feed on the animals head first.

Sometimes you will see them eat frogs feet first. This makes for a more interesting photograph.

I often find these snakes dead in the road. A large Yanbaru forest crab (Candidiopotamon okinawense) took advantage of the situation.

Ornate narrow mouth frog – Amphibians of Okinawa by Shawn Miller

Posted on October 17, 2017 by Admin11

The Ornate narrow-mouth frog (Microhyla okinavensis) is found throughout the Ryukyu Islands. It is one of the smallest frogs found on Okinawa. It can be extremely hard to find due to its small size.

Scientific name: Microhyla okinavensis

Habitat: Forests, mountain slopes, drainage ditches and farm fields.
Diet: Ants, termites and small insects

This small frog is a master of camouflage. I often find it on rocks, plants, and leaves during my night walks.

The fogs take advantage of farmers buckets. They lay their eggs in small pools of water.
