These silver giants can live for over 50 years and undertake massive migrations across ocean basins.
Saltwater vs Freshwater: The Great Divide
The distinction between saltwater and freshwater records reflects fundamental differences in aquatic ecosystems. Saltwater environments generally support larger fish due to higher oxygen content, diverse food webs, and vast territorial ranges.
Marine predators like great whites and marlin benefit from unlimited hunting grounds and abundant prey species. Their massive size results from evolutionary adaptations to open-ocean life.
Freshwater giants face different challenges. Limited space and resources mean freshwater species often develop specialized feeding strategies and extended lifespans. The recent freshwater flounder discoveries show how diverse freshwater ecosystems can be.
Understanding these differences helps anglers appreciate why saltwater records typically exceed freshwater catches in terms of pure weight.
