Snakehead Fish & Saltwater: Can They Survive?

Snakehead fish are not naturally found in saltwater environments. They are native to freshwater habitats in parts of Africa and Asia. Snakehead fish have been known to survive in brackish water areas near river mouths or estuaries, but they do not typically inhabit fully marine environments. Some snakehead species have been introduced to other parts of the world through accidental or intentional releases, and they can establish populations in freshwater ecosystems, posing a threat to native fish species.
