Many deep-sea creatures cope by creating light themselves - also known as bioluminescence. Narwhals dive to this depth up to 15 times a day in search for food. The Japanese Spider Crab is the largest known crab with a maximum leg span of 3.8m.
The deep sea is broadly defined as the ocean depth where light begins to fade, at an approximate depth of 200 m (660 ft) or the point of transition from continental shelves to continental slopes. [1] [2] Conditions within the deep sea are a combination of low temperatures, darkness, and high pressure. [3] .
Reviewed by Karen Osborn, Smithsonian Institution. Below the ocean’s surface is a mysterious world that accounts for over 95 percent of Earth’s living space—it could hide 20 Washington Monuments stacked on top of each other. But the deep sea remains largely unexplored.
How deep is the ocean? At 36,070 feet (10,994 meters) below sea level, Challenger Deep in the Pacific Ocean’s Mariana Trench is the ocean’s deepest known point. Comprehending just how deep this is is a difficult exercise.
The deep ocean. A place so different, filled with strange life forms. But what’s down there? How much do we know about it? As it turns out, not very much. 95% of the ocean remains unexplored, most of which is considered the deep ocean.
From 13m-long (43ft) voracious carnivorous squid, to scuttling Yeti crabs huddling near hydrothermal vents, to tusked whales dwelling thousands of feet down to avoid predatory orcas, sizeable...
The deep sea —that part of the ocean that is perpetually dark—is 103 million square miles in area. However, despite a dramatic increase in exploration in recent decades, we still know very little about this “inner space.” We urgently need to know a lot more. Why? Well…
