#pelagic zone

• Allopelagic — Relating to marine organisms, plankton, or ecological phenomena: originating from a different pelagic zone or region than the local one, having been mechanically transported by major ocean currents or floods into the analyzed environment. This structural type of exogenous element assists in studying hydrological dynamics and nutrient flows between open marine basins and coastal areas.
• Autopelagic — Belonging to or specific to the open pelagic zone, developing, feeding, or adaptively operating autonomously within the upper layers of the water column, independent of the direct influence of the benthic substrate or neighboring coastal zones. In marine ecology, it describes organisms or structural biological processes that spend their entire life cycle in the open ocean, relying exclusively on the internal dynamics of the pelagic ecosystem.
