Anemone-fish of the Ryukyu Islands by Shawn Miller

Have you ever wondered how many species of anemonefish are found in the beautiful waters of Okinawa?  There are six anemonefishes found here. Most are found in shallow water and all live in a venomous sea anemone for protection. Their biggest threats are over-collecting.

(1) Nemo – Is known as the false clown anemonefish (Amphiprion ocellaris). In my opinion is the most beautiful anemone fish of the Ryukyu Islands.

(2) The Tomato anemonefish (Amphiprion frenatus) is the most abundant anemonefish found here. The juveniles sometimes have multiple white stripes.

Sometimes the Tomato anemonefish (Amphiprion frenatus)  can be found in large colonies with over sixty fish living together in multiple sea anemones.

 (3) Clark’s anemonefish ( Amphiprion clarkii ) is fairly common as well. A tough anemonefish for sure!

The juveniles are often found in small nursery anemones. Is it possible these baby anemone fish see the fluorescence of the anemone?  I have always wondered how the hatchlings find a small anemone far away for a reef.

 For some strange reason, the Clarks anemonefish (Amphiprion clarkii) turns dark black when living in the giant carpet sea anemone.

(4) The orange anemonefish (Amphiprion sandaracinos) is uncommon here. They all have a white dorsal stripe running from the lip to the tail.

5) The saddle anemonefish (Amphiprion polymnus) is scarce here. They are usually found living in a large carpet anemone around white fine sand.

(6) The pink anemonefish (Amphiprion perideraion) is fairly common here. They all have a white dorsal stripe running from the eyes to the tail and a narrow white head bar.

The three-spotted damselfish (Dascyllus trimaculatus) seeks shelter in sea anemones at the juvenile stage for protection. It leaves the anemone when its ready and never comes back.

Okinawa offers some of the best shore diving in the world.  What are you waiting for!

Have a great day!

True Fluorescence – Underwater photography by Shawn Miller

” Fluorescence is the absorption of electromagnetic radiation (light) at one wavelength and its re-emission at another, longer wavelength ” Dr Charles Mazel. I attached a link to his website at the bottom of the page for more info.

In order to photograph fluorescence you will need a excitation source (blue light), barrier filter and a camera.

Ryukyu ken – Dogs of Okinawa by Shawn Miller

Ryukyu-ken is scarce breed of dog found on the Island of Okinawa. In the past, these dogs were used to hunt down wild boars in the Yanbaru forest. They are currently designated as an Okinawan national treasure. I have personally seen these dogs hunt wild birds and they have no problems catching them. The Ryukyu ken has a great sense of smell. They can smell their pray from far away. These smart dogs are outstanding hunters.

Its impressive that these dogs hunt such a large powerful animal. Ryukyu wild boar (Sus scrofa).

I was out searching for birds and saw this beautiful male Ryukyu Inu. I knew he was out on a hunting mission.  It was just a matter of being at the right place at the right time.

I often would see the Master walking his dogs on the beach and one day I finally asked him if I could photograph him and his dogs.

I often find some of the most interesting dogs on my photographic adventures exploring the Island. I try to capture their unique personality.  Below are some of my favorite dogs.

Sometimes on my adventures I run into aggressive dogs.  They are just protecting their territory.  I respect their space and leave the scene.
