1. A plankton that produces light. When present in large groups, they make the sea appear to glow. Of the genus, Noctiluca.
2. Any marine animalcule that produces a phosphorescent appearance in the sea.
3. Any of a genus, Noctiluca, of large, sherical, reddish, luminescent protozoa that occur in vast numbers in the sea, causing parts of it to appear luminous at night.

The light-giving substance in phosphorescent animalcules.

1. A reference to bioluminescent organisms emitting light during darkness.
2. A term used to describe high clouds that are visible at night.

1. A reference to bioluminescent organisms that emit light during darkness.
2. Shining by night; as with a noctilucent cloud, a cloud of a kind that occasionally is seen at night in the summer in high latitudes, which occurs in the mesopause (atmosphere) and which some authorities believe is composed purely of cosmic dust and others of ice condensed around cosmic dust particles.
3. Designating or of a luminous cloud of unknown composition, visible at night in the polar regions at an altitude of around 50 miles.

The light-giving substance in phosphorescent animalcules.

Shining at night, phosphorescent.

A genus of bioluminescent marine organisms that, when grouped in large numbers, make the seas phosphorescent.

Shining on everything or shining everywhere.

Any form of light that shines on everything or everywhere.

Luminescence caused by oxidation.

1. Transparent or translucent; clear.
2. Easy to understand; clear and simple in style; such as, a pellucid explanation.
3. Admitting the passage of light; transparent or translucent.

1. The emission of light from a substance as a result of the absorption of electromagnetic radiation. The frequency of the light emitted is lower than that which is absorbed.
2. Luminescence caused by visible light or by infra-red or ultraviolet radiation.
3. Luminescence caused by exposure to light. In lower vertebrates it results from the reflection of light by iridophores in the skin.
4. The quality of being luminescent after being exposed to light or other electromagnetic radiation.

Transparent to X-rays.

Allowing the passage of radiant energy; such as, X-rays, to a varying extent depending on the nature of the object. Also, roentgenolucent.
