    • n noctiluca A genus of free-swimming phosphorescent pelagicinfusorialanimalcules, typical of the family Noctilucidæ. It is sometimes regarded as representative of an order Cystoflagellata (or Rhynchoflagellata). They are ordinarily regarded as monomastigate or uniflagellate eustomatous infusorians, of sub-spheroidal form, strikingly like a peach in shape, and from to of an inch in diameter (thus of giant size among infusorians). There is only one species, N. miliaris, of almost cosmopolitan distribution, but most abundant in warm seas, where they are foremost among various phosphorescent pelagic organisms which make the water luminous.
