Aphotic zone
The aphotic zone (aphotic from Greek prefix ἀ- + φῶς "without light") is the portion of a lake or ocean where there is little or no sunlight.

Atlantic cod
The Atlantic cod (Gadus morhua) is a benthopelagic fish of the family Gadidae, widely consumed by humans.

Benthic zone
The benthic zone is the ecological region at the lowest level of a body of water such as an ocean or a lake, including the sediment surface and some sub-surface layers.

Benthos
Benthos is the community of organisms that live on, in, or near the seabed, also known as the benthic zone.

Bluespotted ribbontail ray
The bluespotted ribbontail ray (Taeniura lymma) is a species of stingray in the family Dasyatidae.

Cuttlebone
Cuttlebone, also known as cuttlefish bone, is a hard, brittle internal structure (an internal shell) found in all members of the family Sepiidae, commonly known as cuttlefish, a family within the cephalopods.

Demersal fish
Demersal fish live and feed on or near the bottom of seas or lakes (the demersal zone).
New!!: Demersal zone and Demersal fish · See more »
Lake
A lake is an area filled with water, localized in a basin, that is surrounded by land, apart from any river or other outlet that serves to feed or drain the lake.

Nautilus
The nautilus (from the Latin form of the original ναυτίλος, 'sailor') is a pelagic marine mollusc of the cephalopod family Nautilidae, the sole extant family of the superfamily Nautilaceae and of its smaller but near equal suborder, Nautilina.

Ocean
An ocean (the sea of classical antiquity) is a body of saline water that composes much of a planet's hydrosphere.
New!!: Demersal zone and Ocean · See more »
Osmosis
Osmosis is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.
New!!: Demersal zone and Osmosis · See more »
Pelagic fish
Pelagic fish live in the pelagic zone of ocean or lake waters – being neither close to the bottom nor near the shore – in contrast with demersal fish, which do live on or near the bottom, and reef fish, which are associated with coral reefs.

Photic zone
The photic zone, euphotic zone (Greek for "well lit": εὖ "well" + φῶς "light"), or sunlight or (sunlit) zone is the uppermost layer of water in a lake or ocean that is exposed to intense sunlight.
New!!: Demersal zone and Photic zone · See more »
Predation
Predation is a biological interaction where a predator (a hunting animal) kills and eats its prey (the organism that is attacked).
New!!: Demersal zone and Predation · See more »
Profundal zone
The profundal zone is a deep zone of an inland body of freestanding water, such as a lake or pond, located below the range of effective light penetration.
New!!: Demersal zone and Profundal zone · See more »
Sea
A sea is a large body of salt water that is surrounded in whole or in part by land.
New!!: Demersal zone and Sea · See more »
Seabed
The seabed (also known as the seafloor, sea floor, or ocean floor) is the bottom of the ocean.
New!!: Demersal zone and Seabed · See more »
Squalene
Squalene is a natural 30-carbon organic compound originally obtained for commercial purposes primarily from shark liver oil (hence its name, as Squalus is a genus of sharks), although plant sources (primarily vegetable oils) are now used as well, including amaranth seed, rice bran, wheat germ, and olives.

Substrate (biology)
In biology, a substrate is the surface on which an organism (such as a plant, fungus, or animal) lives.
New!!: Demersal zone and Substrate (biology) · See more »
Swim bladder
The swim bladder, gas bladder, fish maw or air bladder is an internal gas-filled organ that contributes to the ability of many bony fish (but not cartilaginous fish) to control their buoyancy, and thus to stay at their current water depth without having to waste energy in swimming.

Velvet belly lanternshark
The velvet belly lanternshark (or simply velvet belly) (Etmopterus spinax) is a species of dogfish shark in the family Etmopteridae.
New!!: Demersal zone and Velvet belly lanternshark · See more »
Water column
A water column is a conceptual column of water from the surface of a sea, river or lake to the bottom sediment.

Zooplankton
Zooplankton are heterotrophic (sometimes detritivorous) plankton.
