There’s a snake on my snake boot! I highly recommend wearing snake boots while herping in northern Okinawa.  Check out my post on venomous snakes of Okinawa for more info.

The snakes are sometimes found crossing the road a night.

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.

Diving and Jiving in Okinawa, Japan

Okinawa has some of the best diving in the world. The Ocean is filled with beautiful coral reefs and vast amounts of marine life only found here. The water is warm and the clarity is outstanding. If you ever get the chance to scuba dive in Okinawa, go for it and do not hesitate. Below are a few of my underwater photographs over the years. All the images were photographed on scuba in the beautiful waters of Okinawa-Japan.

This Lion-fish is one of the many venomous animals in the ocean.
