It is most likely that they have adapted to the extreme pressure.
Some creatures have adapted to living in the great pressure found in the depths of the oceans. If they are brought up to the lesser pressure at the surface, they don't usually survive.
Fish adapt to the pressure.
Like us there bodies are made up of a high percentage of water, so they are part of that system. we can go pretty deep ourselves
If they go pass 6,000 feet they won't be able to see because light disappears there. But if they go REALLY far, they could be crushed by the water pressure.
Extreme pressure.
They do not dive deep enough.
Submarine hulls are subject to sea pressure, and that pressure increases the deeper the submarine goes. There are design limits to the amount of pressure that a hull can take, and if that pressure is exceeded by diving too deep, the hull will fail and will be crushed.
High water pressure.
because they have adapted to push outward equally.
because they have adapted to push outward equally.
It is a thermometer that measures in deep sea environments where normal thermometers would be crushed by the enormous pressure!!!!!
if somthing go's in it it will get crushed
