Is there any living thing that does not require sun light?

Answer 1

Yes, some undeground and underwater creatures. There are fish that live on the bottom of oceans where sunlight never reaches - they are transculent/white in color, have red eyes are are blind - because evolutionary they could never see anyway (it is too dark). There are probably hundreds of species.

Answer 2

Yes, there are. Unfortunately I cannot name any sources, but I will tell what I know for sure:
1) In some particular areas of the World Ocean the depth is so large that sunlight cannot penetrate, but still some life forms have been discovered;
2) I recently read an article where they described some newly-discovered caves with lakes inside; so in this lakes some kind of fish were totally transparent since there had never been any light in this caves, and these fish simply didn't need any pigment.

Answer 3

It appears that energy from either the sun or geothermal energy must be used by all living things. Now deep in the trench off the Aleutians we have evidence that geothermal energy is all that some organisms need. This is somewhat analogous to having a totally enclosed building no windows, but with electric lighting to power lights that grow your pot plants. All the energy is coming from nuclear generation, no sunlight involved. What we have is an energy source that allows for reduction of oxidized molecules, whether by sunlight, nuclear generated light, or geothermal springs deep in the Aleutian trench. It would not matter that in absence of the sun the ocean surface would all freeze. Down in the trenches there is not any risk of freezing.

Answer 4

There are some that cannot stand it, but ultimately require it because they depend on something ELSE which depended on sunlight.

For instance, we have quite sophisticated sea creatures that get their energy from geo-thermal springs but would die immediately if they were close enough to the ocean's surface to even detect the sun.

But the Sun is the primary source of gravity in this system and ultimately caused all of the particals to "clump" together, which is why there are planets. For all forms of life that we currently know about, the planet is in some way a requirement for it.

That doesn't mean there aren't other forms of life - but we don't know about 'em.

Answer 5

The "living things" that make their own food using sunlight are called photo-autotrophs. "living things" that eat the stuff that the photo-autotrophs make are called heterotrophs. You and I are heterotrophs.

To complicate thigs there are things called chemo-autotrophs. They get their energy from chemical compounds. There are tons of different bacteria that are chemoautotrophs. At the hot volcanic vents on the bottom of the sea there are several who live on chemicals from the hot water/steam.

Chemo autotrophs are living organisms that do not require sunlight and some of them dont require anything that has to do with the sun but can live anyway.

Answer 6

Look at the species that dwell and live around hydrothermal vents under the ocean. Theres a few that dont require sunlight to live.

Answer 7

Rocks don't need sunlight to exist, but may have living matter in them. But how about this; I believe bacteria and fish very deep in the sea live off of toxic chemicals and do not need SUN to exist.

Answer 8

good question.I guess it would depend on what is considered a life.

The thing is if the Earth requires sunlight to sustain life, wouldn't everything that lives of Earth require sunlight in one way or another?

Answer 9

Direct sunlight ? - Yes, there are living things that do not require direct sun light.

However, if there is no sun light; no living things can be in existance.

Answer 10

I don't think moles require sunlight. Things that live underground and don't come out and yes, Brahm Stroker's vampires!! LOL That was a good answer.
