when I was in my teens, I aspired to be a marine biologist. i had a good microscope at the time but i didn't make the connection between the two!!!  i used to scuba dive and in central Fl. I have been on reefs where i came within 10 ft. of a barracuda!! it just watched me as i watched it.  i made sure that i didn't have on any jewelry like bracelets, necklaces or any shiny things that may have caused it to assume i was a fish!  used to watch J. Cousteau (sic) all the time. recently, i was a fan of the late Steve Irwin.  i used to look at plankton under my microscope but didn't realize that the lowest part of the food chain sustained all of us.  I think marine microbiology is a vital occupation and i should have went in that direction going into college. hindsight is allways 20/20 as they say.   good question that brought back good memories so thanks.  BTW you know that SCUBA is an acronym for Self Contained Underwater Breathing Apparatus.

possible but its more on the no side, conditions not right for life, even for microorganisms that can take extreme temperatures and harsh environment...best of all...no water, its all ice caps!

Try snorkeling.  The water is beautiful!  GOD bless.

try a flotation tank experience. it is incredible...but you got to want to and you should not be claustrophobic or it'd be hell re-invented

who cares?! bottom line is it's good for you!\n\nif you really want to know:\n\nnervous system, cardiovascular systen, muscle system,immune system, respiratory system, digestive system, exocrine and endocrine system....pretty much anything except for the reproductive system depending on what you're doing in the water ;)

Also not mentioned... almost anywhere there's water.  That includes the upper atmosphere, the air you breath, living inside of plants and even cells, antartica, from the bottom of the ocean to the surface, in everything you eat, inside rocks; the list goes on.

yeah just where a life jacket and it will still be well worth it.  plus you can see tons of stuff with out getting in deep water.  I am a good swimmer but I couldn't go under water with my snorkel with out swallowing water anyways.  But maybe I'm just dumb!  Anyways I put on a life jacket and loved it all the same.  As long as you aren't scared of being in the water you'll enjoy it.

This is interesting question. My opinion is: why not!! Maybe some forms of life that we don't know. There is some life forms even 11 km under the sea, under extremely high pressure. Some kinds of bacteria live without air too. Fish don't use the same air like us, but they are alive. There is so many different forms of life even on planet Earth, so why not on other planets? After all, if we did not see something, don't mean this don't exist!

Probably not life as we understand it.  Life as we understand it requires water and some amount of heat.\n\nPluto is really cold.  In the winter, it's atmosphere freezes and falls to the ground as ammonia snow.  The surface temperature in the winter is several hundred degrees below zero, very close to absolute zero.  This is not an environment that supports life as we understand it.  Life is persistent, and can exist in cold places (there is stuff growing on the underside of the ice shelf off Antarctica, in ocean water so cold it would freeze but for the salt content), but that's a little cold.\n\nHowever, amino acid chains, which are one step down from DNA, and not exactly life but pretty close, have been found floating in star clusters.  So maybe there is something on Pluto.  \n\nHowever, if it exists, it is not intelligent life.  We could not communicate with it.  But it would be interesting to study.

I bet you could look this up on the web pretty easily. Why didn't you try?\n\nI bet the diffusivity is pretty good, however, because otherwise, how could fish breathe?

It's a form of underwater swimming

In cold running water frogs can stay underwater indefinitely, certainly for many days if required. \n\nThere are several species of frogs and toads that live their entire lives underwater and never need to surface for air. Such species may go for several years without taking a breath, instead absorbing all their oxygen through their skin.
