- Protected, endangered and threatened species.
What happens when a fish moves from saltwater to freshwater?
A fish that lives in salt water will have somewhat salty water inside itself. Put it in the freshwater, and the freshwater will, through osmosis, enter the fish, causing its cells to swell, and the fish will die.
Why do fish live in rivers?
Like other living creatures, fish must meet certain basic needs for survival. Water, food and shelter are among the most important requirements: Water: Fish not only live in water, but they get oxygen from water. They breathe by taking water into their mouths and forcing it out through gill passages.

What is the difference between freshwater fish and saltwater fish?

Moving into bodies of freshwater meant that they would have to adapt to their new environments. Some of these adaptation became permanent, and led to species differentiation. While marine waters cover more than 70 percent of the earth’s surface, freshwater covers only 1 percent.
How do freshwater fish adapt to their environment?
Constantly changing environments and ease of geographical separation in small bodies of freshwater habitat have resulted in a high degree of diversification of freshwater fish. The constantly changing environments have also forced freshwater fish to become more adaptive to their environment.
