Many of them occur in the mesopelagic zone
between 200 and 400 metres of water depth
. Some species, such as the Antarctic deep-sea coral Flabellum impensum, can live at depths down to 2000 metres – at a water temperature of around 1 degree Celsius. Reefs are narrow, elongated elevations on the sea floor.
Do fish stay in the same area in the ocean?

What fish lives deepest in the ocean?

At what depth is there no light in the ocean?
Light may be detected as far as 1,000 meters down in the ocean, but there is rarely any significant light
beyond 200 meters
. The ocean is divided into three zones based on depth and light level. Although some sea creatures depend on light to live, others can do without it.
At what depth is the ocean dark?
It is sometimes referred to as the midnight zone or the dark zone. This zone extends from
1,000 meters (3,281 feet) down to 4,000 meters (13,124 feet)
. Here the only visible light is that produced by the creatures themselves. The water pressure at this depth is immense, reaching 5,850 pounds per square inch.
What do fish do all day in a tank?
Most aquarium fish are
diurnal
, meaning they move about during the day and rest at night. However, some species are nocturnal and prowl at night, spending daylight hours sleeping in a cave or crevice. Certain species of catfish and plecostomus, some knife fish, loaches and others fall into this category.
Why are deep sea fish not crushed by pressure?
Fish living closer to the surface of the ocean may have a swim bladder – that’s a large organ with air in it, which helps them float up or sink down in the water.
Deep sea fish don’t have these air sacs in their bodies
, which means they don’t get crushed.

How deep can a human dive before being crushed?

about 35.5 km depth
before bone crushes. This is three times as deep as the deepest point in our ocean.
Is the ocean pitch black?
Icy cold, pitch black and with crushing pressures – the deepest part of the ocean is one of the most hostile places on the planet.
At what depth do colors disappear?
Red nearly disappears at
around 5 meters
, followed by orange at 10 meters, yellow at 20 meters, green at 30 meters and eventually even blue at 60 meters. Due to this color loss underwater, underwater photography requires a means of compensation to restore the colors and contrast lost from absorption.
