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 (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.

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.

The Amami woodcock is a master of camouflage. It crouches down low and limits its movements in the leaf litter.  When predators approach the woodcock will fly away in most cases.

The mongoose is the biggest threat to the wildlife of the Ryukyu Islands. It was introduced to the Ryukyu Islands in the1900’s In order to reduce the venomous habu populations. All the islands are still battling this never ending problem.

All the photographs of the Amami woodcock were taken from the car through the back seat window.  In the beginning, I had difficulty with the cameras auto-focus system. I adapted by mounting a Light&Motion GoBe light with a 500 search head to my tripod collar. This allowed the auto-focus system to be extremely responsive using the Canon EF100-400mm f/4.5-5.6L IS II USM.

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.

The Coconut Crab – Terrestrial hermit crabs of the Ryukyu Islands

Coconut crabs are the largest terrestrial hermit crabs of the Ryukyu Islands. They are scarce on the Island of Okinawa due to over-hunting. They are sold in local fish markets for high prices. The meat of the coconut crab is sought after and considered a delicacy.  No conservation programs are set in place to protect this native crab. It is currently listed as data deficient on the IUCN list of Threatened species.

  • Scientific name: Birgus latro
  • Common name: Coconut crab, robber crab and palm thief
  • Distribution: Majority of the Ryukyu Islands
  • Habitat: Coastal forest
  • Diet: Seeds, fruit and carrion
  • Average size: 20-40 centimeters
  • Color: Purple, blue or orange

How to tell the difference between a coconut crab and a hermit crab. They look very similar to the blueberry hermit crab at first, but the coconut crab has protective spines near its eyes. Hermit crabs do not have these spines since they have adapted to retreat into a shell to protect their eyes. The coconut crab does not depend on a seashell as it gets larger. I still have yet to find a juvenile coconut crab adapting with a seashell.

spines that protect the eyes

Terrestrial hermit crabs live in the coastal forest where the treeline and coastline meet. They are the caretakers of the coastal forest. They mainly feed on plants, flowers, fruits, and seeds in the treeline. They also help disperse seeds in the forest, specifically the screw pine tree seeds.
