Why can’t saltwater fish live in freshwater?
Saltwater fish can’t survive in freshwater because their bodies are highly concentrated of salt solution (too much for freshwater). The water would flow into their body until all their cells accumulate so much water that they bloat and die eventually.
What fish can go from freshwater to saltwater?
