The dwelling of an animal or group of similar animals.
A habitat that is in or on an environmental feature or material derived from human activity.
A depression in the sea floor that results from the collision of continental plates; the weight of the sinking plate causes the overlying plate to stretch and thin, causing a basin in the overlying plate. Sometimes, the Earth's crust in these basins stretches so much it cracks, allowing magma through from the mantle beneath. Hence, basins often contain active volcanoes and hydrothermal vents.

A regions or area bounded by drainage divides and occupied by a drainage system; specifically the tract of country that gathers water originating as precipitation and contributes it to a particular stream channel or system of channels, or to a lake, reservoir, or other body of water.
A semi-enclosed coastal body of water with one or more rivers or streams flowing into it, and with a free connection to the open sea.
A tract of crop or grazing land, as well as the group of buildings with and often surrounding a farmhouse, including barns, sheds, and other outbuildings, used for agricultural production.

A facility in which fish are raised commercially in tanks or enclosures, usually for food.
A habitat that is in or on a body of water containing low concentrations of dissolved salts and other total dissolved solids (<0.5 grams dissolved salts per litre).
A description of the geographic distribution, or range, of the taxon. Includes descriptions of global, regional, or political aspects of range and whether the taxon is native or introduced in portions of the range and endemicity.
Gravel is an environmental material which is composed of pieces of rock that are at least two millimeters (2mm) in its largest dimension and no more than 75 millimeters.
