Are there any aquatic or amphibious species of animals that can survive in both salt water and fresh water?

    Yes. Bull sharks have been known to swim far upstream in the Hudson River. A pesky fish we have here in the Great Lakes is the Gobi. The came in with sea-going freighters that dumped their ballast water here. They are quite invasive as they eat the fry of the indigenous species. I'm sure there are others; these were just examples I knew about. This post was edited by Element 99 at June 28, 2021 7:54 PM MDT

    We have the same problem with carp. And they're not even particularly good eating.

    Carp were brought here by Eastern Europeans 150 years ago and now they have become part of ecology. Odd how that works. Romania has a carp festival each year. It is considered a delicacy there. Mom brought a smoked carp home once. It was delish.

    Quite a number of fish species live in the ocean for most of the year, but travel upstream in rivers to spawn in fresh water.
