What are some living organisms that give off light?
Bioluminescence is a side of the natural world that is only now becoming very well-documented and studied. Fireflies are quite well-known, and female anglerfish have a bioluminescent lure dangling from their heads to attract prey and also mates. Many species of deep-sea cephalopods give of light, as well as many different kinds of deep-dea fish and even certain kind of copypods use their bioluminescence to hunt prey and avoid predators.
Can deep sea creatures see in the dark?
After just a few hundred metres there is very little light. Most deep sea creatures have very large eyes that can detect any light that is available. Even though there is virtually no light coming from the surface lots of deep sea creatures produce light through a process called bioluminescence. It is useful to be able to see this light as if you eat the light, you will be eating the creature that it is attached to. Unfortunately some creatures use these lights to draw in their own dinner!
When something does this it gives out light?
Bioluminescence is the emission of light by living organisms. This natural phenomenon occurs in various marine species, plants, and even insects. The light is typically produced through a chemical reaction within the organism's cells.
What are some bugs that glow in dark?
Fireflies, glowworms, and bioluminescent beetles are examples of bugs that can glow in the dark due to a chemical reaction in their bodies that produces light. These insects use bioluminescence for various reasons, such as communication, attracting mates, luring prey, or even to deter predators.
How could humans make use of bioluminescence?
There are uses for Bioluminescence that apply to humans. Luciferase can be produced in a lab and used to help forensic investigators find blood, help researchers study diseases such as cancer and Alzheimer's, help doctor's spot abnormalities and other infectious diseases. It has also been suggested that bioluminescence can be used to create environmentally friendly lights and the U.S Military recently invested money into bioluminescence research to make environmentally friendly helicopter landing indicators that won't get blown away and security systems to tell the difference between friendlies and enemies. Even humans give off traces of bioluminescence (about 1000 times weaker than the human eye can see) we are our brightest in the afternoon and dimmest in the evening.
What other colors of bioluminescence have been found?
Almost all colors. Blue and Green are common but red is found, yellow is even rarer.
Why eyesight is not an important adaptation to life in a deep sea cave?
Sunlight only penetrates the ocean to a depth of about 1,000 meters, or 3,280 feet. Anywhere in the ocean deeper than that does not have visible sunlight, and so visual acuity would theoretically be useless because no matter how good an animal's eyes were it would be unable to see anything.That said, many deep sea creatures have bioluminescence. That means they have small, transparent organs on their exteriors which house microorganisms that are capable of producing light when triggered by the animal. These lights can be used for a species to locate others of its own kind to find mates, and of course, they have the potential to reveal an animal to any predator that can see it, or reveal a predator to prey. Also, the deep sea anglerfish is famous for having a light that it uses to lure prey. Therefore, in the deep sea, even though there is no sunlight, many if not most animals have some amount of vision to detect the bioluminescence of other animals.So it's hard to say that eyesight would be completely useless to an animal that lived in a deep sea cave, but because light is so sparse in that environment, eyes would not have anything to see except the occasional bioluminescent organism.
What does bioluminescene mean?
It is the emission of light occurring at a temperature which is below that of the incandescent bodies. Luminescence includes phosphorescence and fluorescence. I should have added that I only know this through my study of botany. It is seen in both plants and insects. The property of a plant in which this may occurr is of a substance's ability within the plant to transform radiation so as to emit rays of a different wavelength or "color". Certain insects such as a firefly for example can give out light without burning or burning so slowly that heat is not given off from the light.
Do fish that live in the depth of the ocean live in the dark or light?
That depends on how deep. There are fish that live in darkness all the time. Some don't even develop eyes, because they don't need them. But other fish have some kind of glowing light on their bodies that attract prey, so there is some light even down in the blackness.
Car starter led light?
what would be the point, since the starter is normally under the hood, behind the engine, maybe even under the transmission.
How do you change Dome Light Buick Century?
looked at the fuse panel in the car and under the hood and it doesn't even say where the fuse for the dome light is. How stupid is this?
Your 91 jag xj6 has a light on the dash on all the time for a light bulb out even though all lights are working?
Might be the bulb under the hood.
