they can survive because they have lots of packed gear
Because there awsome
There are several reasons. First, the tremendous pressure from being under several miles of seawater would crush any human. Second, there is no air at the bottom of the Pacific. Third, the bottom of the ocean is very cold.
3000 metres
cold, dark, and quiet
Cold
if hey are birds they fly to the south but usullay at the bottom of the ocean it is not froze!
Cold water always sinks.
They are amazingly adaptable creatures so if they go down there I'm sure they can survive it.
Some fish have a special protein in their blood that allow them to survive in extreme cold water temperatures. This protein can act like an extra layer of fat or as a anti-freeze.
Cold water sinks, while warm water rises.
They are in the deep zone and abyssal zone.
The weather in the ocean is different at certain depth's. At the very bottom, it is burning hot. The top of the ocean is as cold as it could get. Most sea animals like/have to live near a heat source, so they stay at the bottom.
The third layer of the ocean is the midnight layer and it reaches to the very bottom of the ocean. It goes down over 20,000 feet. Ii is very dark and cold there. Not a ray of light can shine through. The temperature is almost freezing. Odd and amazing fish live in the midnight layer.
