Thousands of Blue button jellyfish washed ashore Okinawa

Thousands of Blue button jellyfish ( Porpita porpita ) washed ashore on a local beach today.  These beautiful animals have stinging cells called nematocysts.  They can cause skin irritation but generally are not a threat.

I collected a few specimens to photograph in the studio. I was curious to see if this animal would fluoresce under blue light. I used my underwater setup as my lighting studio.  I took a few photos using the Light & Motion Nightsea Blue light.

5 Day Black & White Photo Challenge – Okinawa

I was nominated by Martin Bailey to participate in the 5 Day Black & White Challenge. I had to post one black & white Image each day while challenging another photographer to do the same. It was difficult to find subjects that really popped out in B&W. Below are the five images I posted during this challenge. All images were taken underwater on Scuba in the beautiful waters of Okinawa.
