Worms with tongues ! Blind snakes of Okinawa

Posted on July 15, 2017 by Admin11

The Brahminy bind snake (Ramphotyphlops braminus) is a non-venomous snake found throughout the Ryukyu Islands. They are fairly common here on Okinawa. I often find them in drainage ditches, on roads and sidewalks. These small snakes are overlooked and mistaken for worms.

Scientific name: Ramphotyphlops braminus
Local name: Mekurahebi – Brahminy Blind snake
Distribution: Ryukyu Islands
Habitat: Forests, Grasslands and sugar cane fields
Diet: Termite pupae and ant larvae
Average size: 15cm -21cm
Color: Dark brown

Blind snake -Okinawa, Japan

What is the main difference between the blind snake and a worm ?

The blind snake has scales, a split tongue and a backbone (vertebrate)
Worms have soft skin with ring like segments called annuli and lack a backbone (Invertebrate)

A photograph of a large earthworm (Pontoscolex sp) I found on Kume Island.

The blind snake is the only know snake to be parthenogentic throughout its entire life. The female lays fertile eggs without the need of a male to fertilize the eggs. This is why the blind is so successful in establishing populations.

This small snake is also know as the flower pot snake, thriving in backyard flower pots and gardens.

The blind snake produces a powerful foul smelling odor to deter predators when threatened. I found this out by picking the snake up to remove it off the road.

The blind snake has a modified sharp pointy tail used for anchoring and as a defense mechanism when attacked .

All the blind snakes I have seen on Okinawa are dark brown. My friend Paul found these blind snakes under a rotting log. This was my first time seeing a blue color form.

This week I found three dead blind snakes in Kin village. The warm weather (91-93 Fahrenheit) is drying out the top layer of soil and pushing the snakes out on the pavement.

Akamata – The Ryukyu odd-tooth snake

Posted on June 4, 2017 by Admin11

The Ryukyu odd-tooth snake (Lycodon semicarinatus) is a non-venomous snake found throughout the Ryukyu Islands. They are fairly common here on Okinawa and are usually found at night. The Akamata is a natural enemy of the venomous Habu snake. They are one of the few snakes capable of feeding on venomous pit vipers. More effort should be focused on conserving this native snake for this specific reason. This beautiful snake has been overlooked and needs to be protected. Sadly I see more dead on the road than alive.

- Scientific name: Lycodon semicarinatus
- Local name: Akamata – Ryukyu odd-tooth snake

- Distribution: Ryukyu Islands

- Habitat: Forests, drainage ditches, and housing areas

- Diet: Snakes, lizards, frogs, snakes, birds, baby sea turtles, and rodents.

- Average size: 100cm -180cm

Color: Black, orange with a yellow belly.

They are often found crossing the road at night.

When threatened they pull back, stand high and prepare to strike! They will bite when threatened.

This was my first time seeing a juvenile akamata pull back and puff out its head to resemble the diamond shape of a venomous pit viper.

Is the coincidence or mimicry? I know this is a common occurrence with other non-venomous snakes around the world. I believe this juvenile snake saw me as a threat.

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 eggs are laid in slow-moving and still water sources. The eggs will develop into tadpoles and eventually transform into baby frogs. I often find tadpoles thriving in farming water buckets.

The summer months provide a great opportunity for natural predators.The frogs come together in large numbers.

If you see frogs, there is a possibility that snakes are nearby. The snakes patiently wait for frogs in drainage ditches and still water sources. The Kajika frog is the Hime habu’s favourite meal.

They construct a foam nest on a tree branch above a still water source. Eventually, the foam liquefies when the eggs are ready to hatch.

Not all frogs survive to make the nest. The Akamata is the most common snake on the Okinawan Islands. It feeds on venomous habu snakes, baby sea turtles, lizards, and frogs.

I often find this frog searching for insects on the road.

Okinawan Sword-tailed newt – Endangered species by Shawn Miller

Posted on October 5, 2016 by Admin11

The Okinawan Sword-tailed newt (Cynops ensicauda popei) is an endangered species found on the main islands of Okinawa an Amami. It is currently listed as endangered on the IUCN red list of threatened species. This amphibian is decreasing in numbers due to deforestation and road kill.

Scientific name: Cynops ensicauda popei
Distribution: Okinawa and Anami Islands
Habitat: Forests, wetlands and freshwater streams
Diet: Amphibian eggs, tadpoles, snails, worms and insects
Average size: 100-180mm

Sword tailed newt with stripes

They all have bright orange bellies, which serve as a warning sign to predators that they are poisonous. When threatened they produce a transparent skin toxin.

Poisonous animals are toxic if you eat them or ingest their secretions. Irritations may occur after handling these newts if you have open wounds. Avoid rubbing your eyes or placing your hands in your mouth.

The Sword- tailed newt is often found crossing the road on rainy days in northern Okinawa.

The government has designed specialized wildlife steps for animals that get trapped in roadside drainage ditches. These steps allow the newts to crawl out safely.
