Pyrocystis fusiformis : ウィキペディア英語版 | Pyrocystis fusiformis
''Pyrocystis fusiformis'' is a non-motile, tropical, epipelagic, marine dinoflagellate (flagellate microorganisms), reaching lengths of up to 1 mm. They are especially interesting to many because of their bioluminescent nature which is displayed when ''P. fusiformis'' is disturbed or agitated. In the coastal marine waters, this dinoflagellate causes glowing effects after dark. P. fusiformis was first described in the Proceedings of the Royal Society of London in 1876. ==Morphology== ''P. fusiformis's'' name is derived from its tapered or spindle shape. P. fusiformis is non-motile, which is a characteristic of all members of family Pyrocystaceae, which lose their flagellum by the time these organisms are adults.〔 Each cell is approximately 970 x 163 µm and have a spherical diameter of 374 µm. The cell's chloroplasts actually change the cell's shape as they move closer to the cell's wall in daytime and retract towards the nucleus at night.〔 Bioluminescence is produced through activation of luciferase in the cell's plasma membrane.〔 This produces a bright blue color. The genome of ''P. fusiformis'' contains shared common origin with other dinoflagellates of the luciferase gene.〔
