Why are'nt organisms on the sea floor crusified by water pressure?

They have adapted to their environment.

These answers are taken drectly from the listed link.  \n\nIn animal cells, being in a hypertonic environment results in crenation, where the shape of the cell becomes distorted and wrinkled as water leaves the cell. \n\nPlants thrive in hypotonic environments. Their cells have rigid cell walls that prevent bursting. In fact, the pressure of the cytoplasm against the cell wall keeps the plant from wilting and losing its shape.

the water, earth and moon are always moving......why is some water clear and some murky?  there are so many factors, bacteria in water don't live in warm water, so in tropical places the water is clear, on the other hand, places like east or west coast usa are colder so the water has a higher degree of pollution or looks more "murky"

Limestone Formation 101:\n\n1.) Ocean organisms that contain calcium carbonate in their shells (shellfish or forams)die & settle to the bottom of the ocean floor.\n2.) At certain depths within the ocean, calcium carbonate begins to dissolve.\n3.)Deposits build up over time (millions of years)\n4.)Oceans transgress & regress (move inland & back out again) placing layer upon layer down over time.\n5.)All the layering & pressure from the ocean above causes the dissolved CaCO3 to harden into rock.\n6.)Sometimes pieces of shells are included in the rock (fossiliferous limestone - containing fossils)\n7.)Poof...There you have the recipe for limestone.

i think its because they feed on small fish that are visible from over the sea, or maybe they love what the humidity does to their hair/ feathers\naksugar06 what the hell are you talking about

It was underwater in a quite shallow sea for a couple of hundred million years, the same as the whole of the Dorset and Devon coast, which is why the fossils in the area are all of sea creatures like ammonites. Then later the land was pushed up and the sea bed was lifted above the water. While it was underwater, layers and layers of sand/silt/dead sea creatures built up, which you can now sea as layers in the cliffs in that area. The sea bed was pushed up on a slant, so that if you walked from East Dorset to mid-Devon you are walking back in time, down through almost 200 million years of continous layers and fossils, which is why it's a World Heritage Site.

Whales are air breathing mammals, but they need their bouyancy (so they don't touch bottom and have the affect of gavity on their very dense body tissues). When in too shallow of water, the weight of their own body is so intense that they are then not able to inhale-exhale as easily-deeply as they do when bouyant and self-motile with their strong muscles and movement; then the carbon dioxide builds up in their tissue while the oxygen is not adequately replaced-increased.  Also many of these beached animals have parasites, some in their inner ears or brain that infect their tissues and this seems to impair some of their "judgement" when going close to shore.  They are also quite gregarious socail animals and often want to help other ailing whales; some may be good semaritans who get stuck with the other ailing whales.

Because of scaling, corrosion, and sediment problems.  The dissolved solids in seawater tend to cause excessive problems.  \n\nIf there is any evaporation taking place, the water vapor leaves behind all of the dissolved solids, and scaling and corrosion can occur even where there is no evaporation.

the first response is mostly correct, fish have air bladders and most benthic fish (bottom dwelling) rarely leave the tremendous depths that they live in.  think about a whale which breathes air as we do, they can dive to well beyond the crushing depths of submarines, yet they have no problems with going up and down the water column all the time. they physics behind this are simply, they are adapted to their environment, whcih is the case of whales is both the surface and the lower levels of the ocean. \n\nwhales are a fascinating case, they are able to collect the dangerous by-products of deep diving in their bodies, either through air bladders and special ability to remove toxic gasses from their blood, but they are essentially mammals like humans; obviously you know they breathe the same air we do.  interesting question.  please read more about the ocean if you are interested click the link

I *think* it's because they breathe through their skin - so when the soil and the underground fills up with rain water, they must come to the surface or drown. \n(I'm not 100% sure about this)

Let's consider a deep-sea diver. The pressure pushing on the diver is less at shallow depths than at greater depths. This is because at shallow depths, there is a shorter column on water above the diver than there would be at greater depths. But the pressure the diver feels is not just felt from above! The force is transmitted through the fluid and pushes the diver from all directions, even from below. \n\nPressure within the Earth can be thought of the same way that we think of water pressure on a diver. Under the surface of the ocean, you are under pressure from all directions because of the weight of the column of water above you. Within the Earth, an object is under pressure from all directions due to the weight of the column of rock above the object. This pressure is often called confining pressure, because it is the push from all directions that tends to confine material to the smallest possible volume (space).

"Ocean water is  a complex solution of mineral salts and of decayed biologic matter that results from the teeming life in the seas. Most of the ocean's salts were derived from gradual processes such the breaking up of the cooled igneous rocks of the Earth's crust by weathering and erosion, the wearing down of mountains, and the dissolving action of rains and streams which transported their mineral washings to the sea. Some of the ocean's salts have been dissolved from rocks and sediments below its floor. Other sources of salts include the solid and gaseous materials that escaped from the Earth's crust through volcanic vents or that originated in the atmosphere."

The ocean water can get too hot and kill the animals that live in it because deadly algae and other things grow and kill dolphins and whales etc. Then fish will die and the food chain can go off wack and everything can get messed up and hurt the  animals.

they have a natural process of osmosis that stabalises them with the water and salt content of the sea when they drink the water so that they get enough water in their bodies while being able to live in the salty sea.

There are natural surfactants in the water from certain organisms that grow in the ocean (e.g. kelp, coral). The wave action on the water and surfactants then makes the foam.

True, ants are very light in weight, but in addition to this fact, water surfaces have a thin like layer that bonds because of the structure of water molecules. When divers dive, they have to "break the water" meaning that they have to break the molecule surface of a body of water in order to enter without getting hurt. Its this same surface that allows small insects such as ants to walk on top of water.

Many small organisms rely on ciliary or flagellar motion to move. These mechanisms only work efficiently at low dimensions, i.e. when the density and viscosity of the medium are more important than inertia (which is given by greater body mass).\nThere are also ameboidal movements, caused by relative displacement of citoskeletal elements. These movements are more common in single-celled organisms, but also in some of our own cells (some of the white blood cells, for example)
