Eels have migratory characteristics, sometimes living in sea water, sometimes living in fresh water. Therefore, they are relatively special, can be said to be marine fish, can also be said to be freshwater fish. When eels are young, they live in fresh water such as rivers and lakes. When they reach a certain age, when their bodies are mature and need to reproduce, they will go to the ocean to reproduce, which is their migratory habits.

1. is an eel a marine fish or a freshwater fish

Eel is a kind of fish. If we classify fish from the aspect of living environment, we can divide them into marine fish and freshwater fish. The difference between marine fish and freshwater fish is relatively large, and their living environment is very different. But eels are more special, they can not be divided into one of them, because they can be said to belong to freshwater fish, can also be said to belong to marine fish.

Eels initially live in fresh water, and their growth and development process is carried out in fresh water such as rivers and lakes on land. When they reach a certain age, they will go to the ocean to reproduce. This habit is what we often call the habit of migration. Eels lay eggs in the ocean, and they can only lay eggs once in their lives. This phenomenon is also known as catadromous migration.
