Skeletonema is a single-cell organism belonging to the group of algae called diatoms. Diatoms are unique among the phytoplankton in having a glasslike exterior made of silica. Skeletonema is a chain-forming alga and one of the most commonplace diatoms in the marine coastal environment. Blooms, which often occur in winter and spring, can discolor the water yellow to brown. This diatom is not toxic, but Skeletonema blooms can mechanically damage the gills of fish by clogging them, and killing…

Tuscaridium cygneum  Radiolaria  Even many single-celled organisms are bioluminescent. The radiolarianTuscaridium cygneum forms colonies such as this one in the deep-sea and glows when disturbed.  http://biolum.eemb.ucsb.edu/organism/pictures/radiolarian.html  https://justcutitout.wordpress.com/2012/08/27/i-would-like-to-touch-these/
