Why do animals shine under ultraviolet light?

If you shine ultraviolet light on the bird squirrels, they will shine in pink. If you see the scorpions under moonlight, you will find that amazing blue light is eased. Tablecloths and sharks are capable of producing neon green, and the corals around them are red. All of these brilliant animals are examples of “photoluminescence” or “photoluminescent”; A property that allows some living things to absorb and reflect the sun’s ultraviolet light, moon or artificial resources. A number of animals absorb ultraviolet wavelengths and reflect visible wavelengths; While others have a transcendental color that is not seen with the unarmed human eye. This phenomenon, sometimes known as “fluorescence”, “phosphorus” or “biology”, is more commonly seen in less -known animals and newly discovered places.

In this article quoted from the website National GrammarYou will become more familiar with this common but less well -known phenomenon.

In recent years, biology scientists and enthusiasts have found a lot of brilliant lizards and thousands that shine in a variety of colors when exposed to ultraviolet light. Researchers have succeeded in adding snakes to the high -end list of Nortabanak animals; Of the 5 species of native American continental snakes, about 5 % showed signs of light or ultraviolet light reflection.

Studies have shown that 5 % of the 5 species of frogs also have a radiant skin. Researchers have also been able to identify four species of coral reefs that shine under ultraviolet light, and 4 bird species have been recorded that have lightweight feathers. In the world of mammals, 5 % of the 5 species tested had a bright fur.

Recent studies have described the phenomenon of light as a special and amazing thing; However, Linda Reinhold, Zoology Researcher at James Cook, Australia, acknowledges:

The light phenomenon is not unusual and exceptional! When I was watching the forest in the forest between animals, almost all of them shone.

Scientists have found that “biodegradation” means that when his own organism produces light, it can be used to thank or attract the pair. The hooks and worms do the same in the same way; But the use of light is still in a state of uncertainty. In fact, almost all that scientists know about this phenomenon only goes back to a specific area of ​​biology.

Hayley Crowell, the University of Michigan’s creepwriter, says:

We have made a comprehensive overview of scientific articles that referred to the use of ultraviolet color, and we found that in almost all of these, this process is related to the question of reproduction.

For example, some plants shine with ultraviolet light and use this to direct pollen (insects, birds, etc.) to their flowers, and some birds appear to use ultraviolet colors in the pair selection process; Like the evidence seen in the neon beaks “puffin”. However, this cannot be considered a definite response; Because male and female snakes have no difference in lighting, and this cannot be considered a factor in encouraging the opposite sex in the snakes. Instead, it seems that lighting for snakes and some other creatures acts as a factor for camouflage.

Under UV light

The dry animals are not the only creatures shining under UV light, and this phenomenon seems more rational for some reason in the ocean; Because the underwater environment affects light.

David Gruber encountered a scene that no one had seen until then; A kind of eel that had an unparalleled light. The discovery led Grubar to shine its ultraviolet light to fish of any shape and size that led to the identification of bright turtles and sharks. Later, he and his team made a camera that showed how vibrant and colorful aquatic creatures were.

David Grober says:

This experience was like entry into the hidden world in the ocean; The world where these marine creatures were adapted to; But we didn’t know it.
