Do sharks live in the twilight zone?

How deep is the twilight zone?
The zone between 200 meters (656 feet) and 1,000 meters (3,280 feet) is usually referred to as the “twilight” zone, but is officially the dysphotic zone. In this zone, the intensity of light rapidly dissipates as depth increases. via

What are the 3 zones of the ocean?
There are three main ocean zones based on distance from shore. They are the intertidal zone, neritic zone, and oceanic zone. Distance from shore influences how many nutrients are in the water. via
How much sunlight does the Twilight Zone get?
Dysphotic Zone (Twilight Zone or Mesopelagic Zone)
Also known as the twilight zone (or mesopelagic zone), light intensity in this zone is severely reduced with increasing depth, so light penetration is minimal. About 20 percent of primary production from the surface falls down to the mesopelagic zone. via

Is mesopelagic a Aphotic?
The dark ocean
The layers of the pelagic zone. All but the epipelagic zone make up the aphotic zone. Zones of the water column as defined by the amount of light penetration. The mesopelagic is sometimes referred to as the dysphotic zone. via
Why is it called the twilight zone?
The original phrase 'twilight zone' came from the early 1900s, used to describe a distinct condition between fantasy and reality. The phrase then evolved into a term used to define the lowest level of the ocean that light can reach, and then as an aeronautical term used by the U.S. Air Force. via

Vegetation relies on photosynthesis for energy; sunlight can't penetrate the ocean depths, so plants can't grow in deeper waters. However, shallow coastal waters are a different story. Many varieties of sea vegetation thrive to depths to about 600 feet (183 meters) in the so-called “euphotic zone.” via
