House Geckos of Okinawa

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

  1. They have the ability to lay eggs on vertical walls
  2. They have no eyelids
  3. They can walk upside-down
  4. When threatened they can release their tail
  5. 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.

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

IMG_4077

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.

  • Distribution:  Amami Island
  • Habitat:  Forest streams 
  • Diet:  Insects, worms, and millipedes

Odorrano splendida 6 Amami Island

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.

Okinawa Coral snake – Venomous snakes of the Ryukyu Islands by Shawn Miller

The Okinawa Coral snake (Simomicrurus japonicus boettgeri) is a venomous snake found throughout the Ryukyu Islands. They are difficult to find here on Okinawa and are usually found at night. More effort should be focused on conserving this exotic native snake. This beautiful snake has been overlooked and needs to be protected. It is currently listed near threatened on the IUCN red list of endangered species.

  • Scientific name:  Simomicrurus japonicus boettgeri
  • Local name: Okinawa Coral snake
  • Distribution:  Ryukyu Islands
  • Habitat Forests
  • Diet: Small snakes and lizards
  • Average size:  30cm -60cm
  • Color:  Black, orange with a yellow and black belly.

When threatened the coral snake will coil its tail. This defense mechanism confuses the predator.

These rare snakes are often found crossing the road at night and sadly I have seen more dead than alive.

The underside of the snake is quite beautiful as well.

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.

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

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

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

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.
