What dual ecological classification describes bluefin tuna inhabiting open ocean far from the seafloor?
Answer
Pelagic oceanic species
Bluefin tuna are uniformly classified ecologically as pelagic oceanic species. This designation signifies that their primary habitat is the open ocean water column, living away from the ocean floor, although they are known to seasonally approach coastal areas. Additionally, they are categorized as oceanodromous, which emphasizes their life cycle defined by extensive, long-distance migrations throughout the world's oceans. This habitat preference is strongly linked to their superior physiological adaptations, which allow them to traverse vast distances across varying thermal zones.
