though usually hidden to the human eye, naturally occurring marine biofluorescence can be seen under certain wavelengths of light (like ultraviolet) which causes the cells of the organisms seen here to absorb the light — and some of the photon’s energy — and then emit back a now less energetic light with a longer wavelength and thus a different colour.
biofluorescence is not be confused with bioluminescence (see posts), which is a chemical reaction endemic to an organisms that causes them to glow.
Let us not forget one of the most important things about the Universal Monsters era: The Creature From The Black Lagoon was created by a woman, Milicent Patrick.
Nearly unheard of at the time, ms Patrick is responsible for creating one of the single most recognizable characters, not only in Universal history but in all of film history. She was an incredible talent and she should be honored as such.
