- Fresh water
- Freshwater habitat
- 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).
- Geographic distribution
- 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.
- The natural environment in which an organism lives, or the physical environment that surrounds (influences and is utilized by) a species population.
- Habitat. (2013, August 9). In Wikipedia, The Free Encyclopedia. Retrieved 19:01, August 14, 2013, from http://en.wikipedia.org/w/index.php?title=Habitat&oldid=567783959
- A category or description of the habitat in which the Event occurred.
- Area of dry or relatively dry land surrounded by water or low wetland.
- Iucn red list category
- The geographic latitude (in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic center of a Location. Positive values are north of the Equator, negative values are south of it. Legal values lie between -90 and 90, inclusive.
- The geographic longitude (in decimal degrees, using the spatial reference system given in geodeticDatum) of the geographic center of a Location. Positive values are east of the Greenwich Meridian, negative values are west of it. Legal values lie between -180 and 180, inclusive.
- Marine habitat
- A habitat that is in or on a sea or ocean containing high concentrations of dissolved salts and other total dissolved solids (typically >35 grams dissolved salts per litre).
- Milliliters per liter. A volume per unit volume unit which is equal to one millionth of a liter of solute in one liter of solution.
- Near threatened
- A taxon is Near Threatened when it has been evaluated against the criteria but does not qualify for Critically Endangered, Endangered or Vulnerable now, but is close to qualifying for or is likely to qualify for a threatened category in the near future.
- Continuous saline-water bodies that surround the continents and fill the Earth's great depressions.
- A dimensionless ratio unit which denotes numbers as fractions of 100.
- Population trend
- Practical Salinity Units. The conductivity ratio of a sea water sample to a standard KCl solution. Used to represent salinity.
- Natural freshwater surface streams of considerable volume and a permanent or seasonal flow, moving in a definite channel toward a sea, lake, or another river; any large streams, or ones larger than brooks or creeks, such as the trunk stream and larger branches of a drainage system.
- Broken rock that appears at the bottom of crags, mountain cliffs or valley shoulders.
- That part of the land in immediate contact with a body of water including the area between high and low water lines.
- Terrestrial habitat
- A habitat that is on or at the boundary of the surface of the Earth.
- Volcanic field
- A region of the earth's crust that is prone to localized volcanic activity.
- Water dissolved O2 concentration
