Definission: 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.
Definission: 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.
Definission: Fully formed eggs are retained and hatched inside the maternal body and are released as live offspring (Lincoln et al., 1998). No nutrition is derived from the mother
Definission: where individuals of the same species (conspecifics), maintain spatial proximity with one another over time with mechanisms of social attraction
Definission: Solitary animals are those that spend a majority of their lives without others of their species, with possible exceptions for mating and raising their young. Antonyms for a solitary animal include a social animal or a colonial animal.
