Biota closely associated with the bottom of a water body.
Organisms that live on or in the bottom of the sea.
the plant or animal life whose habitat is the bottom of a sea, lake or river
plants and animals living on the stream bottom.
Non-planktonic animals (not being suspended in water) associated with freshwater substrata (upper layer of the sediment in rivers and ponds) at the sediment-water interface. (Wetzel, 1983)
Collective term for sediment and the organisms that dwell there. Adjective: benthic
bottom-dwelling aquatic biota.
Animals without backbones, living in or on the sediments, a size large enough to be seen by the unaided eye, and which can be retained by a U.S. Standard No. 30 sieve (28 openings/inch, 0.595-mm openings). Also referred to as benthic macroinvertebrates, infauna, or macrobenthos.
Collectively, those plants and animals, usually invertebrates, living on or near the bottom of the bay or ocean (benthic, adj.).
In fresh water and marine ecosystems, organisms attached to, resting on, or burrowed into bottom sediments.
A group of organisms, most often invertebrates, that live in or on the bottom in aquatic habitats (such as clams that live in the sediments) which are typically immotile or of limited motility or range.
The communities of aquatic life which dwell in or on the bottom sediments of a water body.
organisms living on the bottom of aquatic and marine ecosystems.
a region including the bottom of the sea and the littoral zones
organisms (plants and animals) that live at or near the bottom of a sea
Organisms that lie in and on the bottom of the ocean floor.
fauna and floraliving on the seabed
Animals and plants associated with the sea bottom.
Animals, such as clams, and plants, such as kelp, that live on the bottom of the ocean regardless of water depth. Most plants live in shallow water
those organisms attached to, living on, or in the seabed.
term for the organisms living in or on the bottom of a body of water.
The plants and animals that live at the bottom of a body of water (ocean, river, lake, pond, etc.) either attached or unattached to substrate (sediment, rock, plant, etc.). ( benthos)
organisms associated with the bottom sediments of water bodies.
The sum total of organisms living in, or on, the sediments of aquatic habitats.
Collectively, all organisms living in, on, or near the bottom substrate in aquatic habitats (examples are oysters, clams, burrowing worms).
All plants and animals that live on or in the sea floor
Organisms living on or in the ocean bottom.
Collective synonym for benthic organisms, but frequently also applied to the floor or deepest part of a sea or ocean.
Organisms that live on or in the bottom sediments of a water body.
Benthos (adj. Benthic) refers to the community of invertebrate organisms that dwell either entirely or for part of their life cycle in the bottom sediments of lakes and rivers. The health and abundance of certain worms and insect larvae and nymphs are used as indicators of contaminant toxicity.
All the plant and animals living on or closely associated with the bottom of a body of water.
In freshwater and marine ecosystems, the collection of organisms both attached to or resting on the bottom sediments and burrowed into the sediments. In terms of size, benthos are generally divided into three categories: meiobenthos, the organisms that pass through a 0.5 millimeter sieve; macrobenthos, those that are caught by grabs or dredges but retained on the 0.5 millimeter sieve, and epibenthos, those organisms that live on rather than in the seabed.
bottom dwelling or substrate-oriented organisms.
plant and animal life associated with aquatic floor and the sea bed
The assemblage of organisms associated with the bottom sediments of aquatic systems. Benthos usually refers to the animals associated with the bottom sediments, but can also include plant and microbial communities. [Gk. benthos, depth of the sea.
The collection of organisms living on or in sea or lake bottoms. The bottom of a sea or lake. See also: pelagic
the bottom of a body of water and the organisms that live there
The collection of organisms living on the sea floor or the bottom of other bodies of water.
The whole assemblage of plants or animals living on the bottom of a water body; distinguished from plankton.
Zone at the bottom of a body of water inhabited by mussels, clams, crustaceans, and other aquatic life.
Those animals who live on the SEDIMENTS of the sea floor, including both mobile and non-mobile forms.
"bottom" of a body of water (e.g., lakes, streams, and ponds), providing habitat for various aquatic organisms on or within.
assemblage of organisms inhabiting the bottom of streams.
organisms that live on or near the ocean floor, such as seaweed, kelp, and tube worms
bottom-dwelling aquatic plants and animals.
bottom-dwelling flora and fauna; from tiniest microbenthos (bacteria) to medium-sized meiobenthos (nematode worms) to the highly visible macrobenthos (clams, polychaete worms).
A term applied to organisms that live on or in the bottom of a body of water and its sediment (benthic zone).
Bottom-dwelling organisms. Compare decomposer, nekton, plankton.
Aquatic plants or animals that live on or near the bottom of a water body.
Those organisms that live in or on the bottom of a body of water. The benthos is one of three divisions of aquatic life; the others are the nekton ("swimmers") and the plankton ("drifters").
organisms living on, or in, the bottom material of lakes and streams.
The plant and animal organisms that live on the sea floor. Often divided into two categories: deep-sea benthos, below 200 meters and the littoral benthos, from 200 meters to the high-water spring tide level.
Those organisms attached to, living on, in or near the bottom.
Pertaining to the bottom. Animals that live on or near the bottom of a stream or lake.
In oceanography, marine geology and biology, benthos are the organisms and habitats of the sea floor; in freshwater biology they are the organisms and habitats of the bottoms of lakes, rivers, and creeks. Animals belonging to the benthos are sometimes referred to as zoobenthos, while plants are referred to as phytobenthos.
