Like salmon, it lives both in freshwater and saltwater. But its life-cycle is exactly the reverse of salmon’s: the eel is a catadromous species. It is born in saltwater and migrating to freshwater to grow and mature before returning to saltwater to spawn and die. The American Eel can live as long as 50 years.
Can freshwater eels live in saltwater?

How long do freshwater eels live?
Eels migrate up streams as elvers to find suitable adult habitat. After many years (15-30 years for shortfins, 25 years for longfins, and sometimes up to 80 years) they migrate to the Pacific Ocean to breed and die. Eels are secretive, mainly nocturnal and prefer habitats with plenty of cover.

The salt osmotically pulls moisture from the eel, making it increasingly impossible for the fish to breathe. [3] Death takes several hours, and the eel loses something like 5% of its body weight in the process.
Are eels asexual?
Researchers believe they spawn via external fertilization. The females release millions of eggs into the water where they are fertilized by the male’s sperm. After this, they die. The reproduction of eels has long been a mystery.
