I believe it's do to the fact that they have no gas inside their body. We cannot survive because the gas inside us becomes crushed by the extreme pressure, due to the fact that gas had no defined volume. Liquid does however so it creates an equilibrium. I believe
The pressure in the abyssal zone increases with depth due to the weight of the overlying water. It can reach extreme levels, enough to compress gases and crush most structures. Deep-sea organisms in this zone have adapted to survive under these high-pressure conditions.
Because the salt content is way too high for any animal to survive.
they have gills that aloughs them to breath
Orca are sea animals and survive in water -- anywhere they in the world.
The deep sea has high water pressure due to the weight of the water above it. As you descend deeper, the pressure increases significantly. Conversely, the air pressure at deep sea depths is relatively constant and does not change as dramatically as water pressure.
No. While the suit might protect you from the pressure,it could not protect you from the extremely high temperatures.
They have evolved to deal with it Many of them have pressure equalisers within their own bodies.
Because if there a sea animal and they are born in the sea then they adapted to swimm
they use very strong, thick materials or equilize the pressure on the inside to be the same as the outside
Since there is no food chain in Antarctica, it's too cold, there are no animals that live there. Sea animals eat other sea animals in the shortest food chain on earth.
For the same reason any other animal eats. To survive.
A person could not survive on Venus because of the extreme heat and pressure. The temperature is about 850 degrees Fahrenheit and pressure is more than 90 times sea level pressure on Earth.
