Glossary for Squatina aculeata
- The general region of indefinite width that extends from the sea inland to the first major change in terrain features.
- conservation status
- continental shelf
- The extended perimeter of each continent, which is covered during interglacial periods such as the current epoch by relatively shallow sea.
- critically endangered
- A taxon is Critically Endangered when the best available evidence indicates that it meets any of the criteria A to E for Critically Endangered, and it is therefore considered to be facing an extremely high risk of extinction in the wild
- A plane angle unit which is equal to 1/360 of a full rotation or 1.7453310^[-2] rad.
- drainage basin
- 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.
- This taxon is still in existence, as opposed to extinct.
- extinction status
- Indicates whether a taxon is extant (living today) or extinct.
- A category or description of the habitat in which the Event occurred.
- 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.
- Meters. A length unit which is equal to the length of the path traveled by light in vacuum during a time interval of 1/299 792 458 of a second.
- marine biome
- An aquatic biome that comprises systems of open-ocean and unprotected coastal habitats, characterized by exposure to wave action, tidal fluctuation, and ocean currents as well as systems that largely resemble these. Water in the marine biome is generally within the salinity range of seawater: 30 to 38 ppt.
- 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).
- mediterranean sea biome
- The mediterranean sea biome comprises mostly enclosed seas that have limited exchange of deep water with outer oceans and where the water circulation is dominated by salinity and temperature differences rather than winds.
- A liquid or semi-liquid mixture of water and some combination of soil, silt, and clay.
- population trend
- This organism is known to be present in this location or region
- sea floor
- The ground surface that lies beneath a sea.
- Sediment is an environmental substance comprised of any particulate matter that can be transported by fluid flow and which eventually is deposited as a layer of solid particles on the bedor bottom of a body of water or other liquid.
- The part of an elevation or depression between the relatively flat surrounding area and the peak of a mount or the bottom of a depression.
- water depth
- The depth of seawater at a location where this organism has been observed or collected.
