What is the difference between a fresh water fish and salt fish?

Freshwater fish live in bodies of water with a low salt content, such as rivers, lakes, ponds, and certain underground aquifers. These fish are typically able to extract the salts they need from the water and their food.

Some Examples of Fresh Water Fishes - Salmon, Catfish, Carp, Tilapia

Saltwater fish live in oceans and other bodies of water with a high salt content. These fish must be able to regulate their internal salt levels in order to survive in their environment. They typically do this by drinking large amounts of seawater and removing excess salt through their gills and kidneys.

Some Examples of Salt Water Fishes - Tuna, Flounder, Cod, Shark

Here is a table summarizing the key differences between freshwater fish and saltwater fish:

| Feature | Freshwater Fish | Saltwater Fish |

| ------------- | ------------------------------- | -------------- |

| Environment | Low salt content, such as rivers, lakes, ponds | High salt content, such as oceans |

| Extracting Salt | Extract salts from water and food | Extract salts from gills and kidneys |

| Examples | Salmon, Catfish, Carp, Tilapia | Tuna, Flounder, Cod, Shark |
