Information
Ecological parameter: aquatic stages according to Tachet
Parameter group: life & body related parameters
Explanation:
The trait lists the aquatic stages of a species. Many (holobiotic) organisms are "freshwater-residenst" and spend their entire life cycle in water, others (amphibiotic) are present in aquatic systems only during specific periods of their life cycle. Four categories are defined.
