No. You experience greater and greater pressure as you swim farther and farther below the surface of the water. This is because there is a greater height of water pressing down on you from above.
Of course when you swim under the surface of the water. The lower you go in the water, the greater the pressure. That's why divers have gauges with them to determine their depth or to know how deep they are in the ocean.
salt water weights more for a given volume than freshwater and that causes the increase in pressure
if you are swimming at the same depth the pressure will be the same. Depth affects pressure directly proportionally. That is if you swim deeper the pressure will become greater. If you swim up the pressure will become less. The size of the body of water does not affect pressure. Think of it this way, the further down you swim the more your ears hurt. they hurt because of the increase in pressure.
The deeper you swim, the greater pressure becomes because there is more water above you pressing down.
Atmospheric pressure, among other things, increases as elevation is reduced. This is because as you get lower, there is more atmospheric mass above wherever you are. This is the same underwater. Pressure increases as you swim down and more and more water is situated above you.
they eat more,can swim better,and they are heavyer.
Your guppy might be suffering from swim bladder disease. If you have any more guppies i would keep an eye on them.
because when deep sea fish are brought up to the surface after living in such extreme pressure areas for their entire lives, the lack of pressure on them causes them to puff up. so basically, it's because the pressure greatly decreases.
no, auks, ducks, murres, and puffins can also swim, gulls can swim on the surface
above the water
Although it is a commonly held belief that skeletons cannot swim, this is not entirely correct. While slow and inefficient, the skeletal surface does provide enough impermeable surface area to exert pressure against a liquid mass, enabling skeletons to swim, albeit poorly. An interesting side-note, however, is that skeletons are among the least at-risk from sharks, due to their complete lack of blood.
Whenever dolphins need to get air they temporarily swim at the surface of the water. Baby Dolphins when born are pulled up to the surface so they don't drown.
