The abyssal zone
According to folklore and mythology, the Leviathan is said to live in the depths of the ocean, specifically the abyssal zone where there is complete darkness. It is often described as a massive sea creature or monster that is almost impossible to defeat. However, the Leviathan is a mythical creature and not confirmed to actually exist.
The Abyssal Zone is one of the many benthic zones we have highlighted to describe the deep oceans. This particular zone is found at depths of 2,000 to 6,000 meters (6,560 to 19,680 feet) and stays in perpetual darkness.
The abyssal zone is the region of the deep ocean that is just above and on the ocean floor.
There are positive and negative effects we have on the abyssal zone. Some negative effects are we have poluted the abyssal zone. We can't get down far enough to clean the abyssal zone. Some positive effects we have on the abyssal zone are reasearching the animals down in the abyssal zone and we can find out if they could live in shallower water of it they have to live in deep water.
