The would depend on the animal.
The Adlantic OceanThe adlantic is the shallowest as well as the smallest of the worlds oceans. Arctic Ocean's average depth is only one quarter that of the Pacific. Average depth: 3,407 feet (1,038 m)Deepest point: 17,881 feet (5,450 m) in the Eurasian Basin
In the deepest bit of the ocean. I think it's in the Pacific ocean.
The abyss is the deepest part of the ocean that has not been explored. There is a movie that was made about it in the eighties I think.
The deepest part if the ocean is called the ABYSSOPELAGIC it is about 6000 meters
Challenger deep.
The deepest ocean in the entire world is the Pacific Ocean, which has on average a depth in the region of 13,215 feet. Although we do not know just how deep some parts are, scientists think that the deepest part known to mankind is 36,198 feet and this is actually found in the Mariana Trench in the Mariana Islands
in the big area where minos and catapillers meet just kidding in a deep dark area in the ocean i think my advior tells me this stuff
Today scientists know that on average the ocean is 2.3 miles (3.7 kilometers) deep, but many parts are much shallower or deeper. The deepest parts of the ocean are trenches – long, narrow depressions, like a trench in the ground, but much bigger. The HMS Challenger sampled one of these zones at the southern end of the Mariana Trench, which might be the deepest point in the ocean. Known as the Challenger Deep, it is 35,768 to 36,037 feet deep – almost 7 miles (11 kilometers).
Caloris Basin I think is the deepest and the youngest too.
I don't think they live in the Indian Ocean
Because there are living cells in it(Ocean Sponges)
the ocean - the pasific ocean takes up a third i think
