Frogs of Okinawa by Shawn Miller

Individuals that study amphibians are know as herpetologists. The act of searching for these beautiful animals is known as herping. Okinawa has twelve species of frogs. They all have the ability to live in the water and on the land. Most are nocturnal and feed on insects during the night. They are found in local parks, forests, streams, puddles, and on the road at times.

If you would like to learn more about a specific frog, I attached a link above each photograph. Links in red are endangered species.

Searching for Cephalopods by Shawn Miller

Lately, I have been getting out a lot more on night dives. The conditions have been great for Scuba diving and underwater macro photography.  Diving at night is exciting because you never know what you will find. My last dive I stumbled upon a few new brightly colored nudibranchs and an undescribed pygmy cephalopod known as the pharaoh cuttlefish.

Could this pygmy cuttlefish be an undescribed species or just a clever juvenile broadband cuttlefish resembling the sand?

  • Scientific name:  Sepia sp
  • Common Name: Pygmy or Pharaoh Cuttlefish
  • Found:  Kin bay, Okinawa
  • Habitat: Sand bottom @ night
  • Depth:  35feet 
  • Size:  17mm

DSC_2082 DSC_2093 DSC_2104DSC_2111More than likely this pygmy cuttlefish is Sepiella inermis.  The pharaoh cuttlefish is absolutely stunning. I found this large specimen sand-dwelling during a night dive.

If you have never been night diving I highly encourage you to try it. If you want to learn more about Cephalopods of Okinawa, check out my post on the beautiful Blue-ringed octopus.

Psychedelic Spiders of Okinawa by Shawn Miller

I have been photographing fluorescence for over five years now. Mainly underwater but lately I have been testing the technique on land.  I often find insects, spiders, and plants that fluoresce using a specialized Light&Motion Sola Nightsea light.  Some of the micro-spiders fluoresce brightly under blue light, the challenge is to get an acceptable photograph.

Below are some comparison photographs of spiders. The first photograph was taken under blue light and the second under white light using on-camera flash. All the spiders were photographed in their natural habitat on the beautiful Island of Okinawa.

The giant wood spiders (Nephila maculata) of Okinawa fluoresce under UV light.

I used my nauticam underwater setup with NIGHTSEA’s fluorescence excitation filters to photograph the wood spiders.
