Ryukyu Long tailed Giant Rat – Ryukyu Islands

The Ryukyu Long-Tailed Giant Rat (Diplothrix legata) is an endangered species found on Amami, Tokuno and Okinawa Island. This rare species is currently listed as endangered on the IUCN red list of threatened species.  It’s biggest threats are deforestation, feral cats, dogs and the introduced mongoose. I often see it crossing the road during the night in the Yanbaru forest. Please pay attention to crossing wildlife and drive at a safe speed.

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.
