"When I first saw a sea sapphire I thought I was hallucinating. The day had been anything but normal, but this part will always stand out. I’d spent the afternoon on a small dingy off the coast of Durban, South Africa. It was muggy, and I’d been working for hours–-throwing a small net out, and pulling in tiny hauls of plankton that I’d then collect in jars. As I looked through one jar, the boat rocking up and down, I saw for an instant a bright blue flash. Gone. Then again in a different place. An incredible shade of blue. Maybe I’d been in the sun too long? Maybe I was seeing things? It wasn’t until I got back to the lab that I discovered the true beauty and mystery of these radiant flashes."
The females are parasitic upon salps. The males are invisible - with the exception of when they flash like gemstones
When they’re abundant near the water’s surface the sea shimmers like diamonds falling from the sky. Japanese fisherman of old had a name for this kind of water, “tama-mizu”, jeweled water."
