How does the American eel adapt to its environment?

Answer 1

After American eels reaches maturity in freshwater lakes and rivers, they make their way to the ocean. They swim or drift with currents until they reach the Sargasso Sea between Bermuda and Puerto Rico. Here the eels die after spawning.

Answer 2

Salmon and eels are examples of euryhaline organisms. These organisms are able to adapt to a wide range of salinities. Euryhaline organisms are commonly found in habitats such as estuaries and tide pools where the salinity changes regularly. Some organisms are euryhaline because their life cycle involves migration between freshwater and seawater environments, which is the case with salmon and eels.
