Дефиниција: A taxon is Vulnerable when the best available evidence indicates that it meets any of the criteria A to E for Vulnerable, and it is therefore considered to be facing a high risk of extinction in the wild.
Дефиниција: 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.
Дефиниција: 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).
Дефиниција: Body/caudal fin propulsion, retaining eel-like body movements and exploiting interactions between the sidewash from an anterior median fin with the next posterior fin, increasing its effective angle of attack
Дефиниција: An oceanodromous fish, like an anadromous or catadromous fish, is migratory. Unlike anadromous or catadromous fish, an oceanodromous fish spends its whole life in salt water.
Дефиниција: 1) Producing live offspring from within the body of the parent (Lincoln et al., 1998). 2) Development of an embryo within the body of the parent, in part, resources passing directly from parent to embryo (Barnes et al., 2006).
Дефиниција: where individuals of the same species (conspecifics), maintain spatial proximity with one another over time with mechanisms of social attraction
