The main image is a composite I made (overlay) of the brittle star bioluminescencing in the dark and the image of the brittle star hit with a flash. I had read that Amphipholis squamata had bioluminescence but hadn't seen any images from the California coast, so I brought home a few from the docks at Jack London and took lots of photos, some 30 minutes long at my highest ISO and got nothing. I did some more reading and 200mM KCl can cause a depolarization event leading to extreme bioluminescence so I dissolved a Emergen-C vitamin fizzy drink that has potassium carbonate in it in a minimal amount of water and added that to a few isolated brittle stars and BAM! Light show!

Very tiny (up to 10-15 mm), numerous brittle stars found crawling among fouling community of Styela clava tunicates collected at the floating dock at MCRD, Boat Channel, San Diego Bay - Photographed in small tray with brittle star submerged in bay water, brittle star flaying arms about - Small size, white spot on disk where each arm joins disk, somewhat circular disk, grey coloration and arm appearance suggests the species is Amphipholis squamata - common name Dwarf Brittle Star, - Literature reports species occurs world-wide. -

Many of these mixed in with a bunch of stuff on a rope hanging from the dock.
