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!

Nudibranchs – Colorful sea slugs of Okinawa

Nudibranchs are shell-less gastropods. They are some the most bizarre looking underwater animals found in our oceans. They can be challenging to to find due to their small size and confusing patterns. Nudibranchs are slow moving, delicate and lack a protective shell. Some are extremely distasteful and bright colors warn predators that they are toxic. Some even have the ability to ingest stinging cells and use them as a form of protection.

The best way to find sea slugs:    Move slow!  Search around sponges, hydroids, sea squirts, anemones, soft coral, rocks and reef ledges.

Train the eye:  They can be challenging to find, I recommend tagging along with experienced divers that already have an eye for finding them.

Below are some of my favorite images of sea slugs. Photography by Shawn M Miller.

Nature Therapy – Photo Exhibition by Shawn Miller

The Exhibition will be held at the Okinawa Institute of Science and Technology (OIST)  January 14th through February 29th.  The free photo exhibition is open from 9:00 to 17:00 every day. The exhibition will feature forty inspiring images of underwater animals, crabs with beach trash homes and the endangered species of Okinawa.  Photography By Shawn Miller. The wonderful people at OIST were kind enough to make this exhibition  take place and produce beautiful advertisement posters.
